CONFIGURATION FILE ------------------ The Git configuration file contains a number of variables that affect the Git commands' behavior. The `.git/config` file in each repository is used to store the configuration for that repository, and `$HOME/.gitconfig` is used to store a per-user configuration as fallback values for the `.git/config` file. The file `/etc/gitconfig` can be used to store a system-wide default configuration. The configuration variables are used by both the Git plumbing and the porcelains. The variables are divided into sections, wherein the fully qualified variable name of the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive, allow only alphanumeric characters and `-`, and must start with an alphabetic character. Some variables may appear multiple times; we say then that the variable is multivalued. Syntax ~~~~~~ The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The '#' and ';' characters begin comments to the end of line, blank lines are ignored. The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are case-insensitive. Only alphanumeric characters, `-` and `.` are allowed in section names. Each variable must belong to some section, which means that there must be a section header before the first setting of a variable. Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in the example below: -------- [section "subsection"] -------- Subsection names are case sensitive and can contain any characters except newline and the null byte. Doublequote `"` and backslash can be included by escaping them as `\"` and `\\`, respectively. Backslashes preceding other characters are dropped when reading; for example, `\t` is read as `t` and `\0` is read as `0` Section headers cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have `[section]` if you have `[section "subsection"]`, but you don't need to. There is also a deprecated `[section.subsection]` syntax. With this syntax, the subsection name is converted to lower-case and is also compared case sensitively. These subsection names follow the same restrictions as section names. All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form 'name = value' (or just 'name', which is a short-hand to say that the variable is the boolean "true"). The variable names are case-insensitive, allow only alphanumeric characters and `-`, and must start with an alphabetic character. A line that defines a value can be continued to the next line by ending it with a `\`; the backquote and the end-of-line are stripped. Leading whitespaces after 'name =', the remainder of the line after the first comment character '#' or ';', and trailing whitespaces of the line are discarded unless they are enclosed in double quotes. Internal whitespaces within the value are retained verbatim. Inside double quotes, double quote `"` and backslash `\` characters must be escaped: use `\"` for `"` and `\\` for `\`. The following escape sequences (beside `\"` and `\\`) are recognized: `\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB) and `\b` for backspace (BS). Other char escape sequences (including octal escape sequences) are invalid. Includes ~~~~~~~~ The `include` and `includeIf` sections allow you to include config directives from another source. These sections behave identically to each other with the exception that `includeIf` sections may be ignored if their condition does not evaluate to true; see "Conditional includes" below. You can include a config file from another by setting the special `include.path` (or `includeIf.*.path`) variable to the name of the file to be included. The variable takes a pathname as its value, and is subject to tilde expansion. These variables can be given multiple times. The contents of the included file are inserted immediately, as if they had been found at the location of the include directive. If the value of the variable is a relative path, the path is considered to be relative to the configuration file in which the include directive was found. See below for examples. Conditional includes ~~~~~~~~~~~~~~~~~~~~ You can include a config file from another conditionally by setting a `includeIf..path` variable to the name of the file to be included. The condition starts with a keyword followed by a colon and some data whose format and meaning depends on the keyword. Supported keywords are: `gitdir`:: The data that follows the keyword `gitdir:` is used as a glob pattern. If the location of the .git directory matches the pattern, the include condition is met. + The .git location may be auto-discovered, or come from `$GIT_DIR` environment variable. If the repository is auto discovered via a .git file (e.g. from submodules, or a linked worktree), the .git location would be the final location where the .git directory is, not where the .git file is. + The pattern can contain standard globbing wildcards and two additional ones, `**/` and `/**`, that can match multiple path components. Please refer to linkgit:gitignore[5] for details. For convenience: * If the pattern starts with `~/`, `~` will be substituted with the content of the environment variable `HOME`. * If the pattern starts with `./`, it is replaced with the directory containing the current config file. * If the pattern does not start with either `~/`, `./` or `/`, `**/` will be automatically prepended. For example, the pattern `foo/bar` becomes `**/foo/bar` and would match `/any/path/to/foo/bar`. * If the pattern ends with `/`, `**` will be automatically added. For example, the pattern `foo/` becomes `foo/**`. In other words, it matches "foo" and everything inside, recursively. `gitdir/i`:: This is the same as `gitdir` except that matching is done case-insensitively (e.g. on case-insensitive file sytems) A few more notes on matching via `gitdir` and `gitdir/i`: * Symlinks in `$GIT_DIR` are not resolved before matching. * Both the symlink & realpath versions of paths will be matched outside of `$GIT_DIR`. E.g. if ~/git is a symlink to /mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git` will match. + This was not the case in the initial release of this feature in v2.13.0, which only matched the realpath version. Configuration that wants to be compatible with the initial release of this feature needs to either specify only the realpath version, or both versions. * Note that "../" is not special and will match literally, which is unlikely what you want. Example ~~~~~~~ # Core variables [core] ; Don't trust file modes filemode = false # Our diff algorithm [diff] external = /usr/local/bin/diff-wrapper renames = true [branch "devel"] remote = origin merge = refs/heads/devel # Proxy settings [core] gitProxy="ssh" for "kernel.org" gitProxy=default-proxy ; for the rest [include] path = /path/to/foo.inc ; include by absolute path path = foo.inc ; find "foo.inc" relative to the current file path = ~/foo.inc ; find "foo.inc" in your `$HOME` directory ; include if $GIT_DIR is /path/to/foo/.git [includeIf "gitdir:/path/to/foo/.git"] path = /path/to/foo.inc ; include for all repositories inside /path/to/group [includeIf "gitdir:/path/to/group/"] path = /path/to/foo.inc ; include for all repositories inside $HOME/to/group [includeIf "gitdir:~/to/group/"] path = /path/to/foo.inc ; relative paths are always relative to the including ; file (if the condition is true); their location is not ; affected by the condition [includeIf "gitdir:/path/to/group/"] path = foo.inc Values ~~~~~~ Values of many variables are treated as a simple string, but there are variables that take values of specific types and there are rules as to how to spell them. boolean:: When a variable is said to take a boolean value, many synonyms are accepted for 'true' and 'false'; these are all case-insensitive. true;; Boolean true literals are `yes`, `on`, `true`, and `1`. Also, a variable defined without `= ` is taken as true. false;; Boolean false literals are `no`, `off`, `false`, `0` and the empty string. + When converting value to the canonical form using `--bool` type specifier, 'git config' will ensure that the output is "true" or "false" (spelled in lowercase). integer:: The value for many variables that specify various sizes can be suffixed with `k`, `M`,... to mean "scale the number by 1024", "by 1024x1024", etc. color:: The value for a variable that takes a color is a list of colors (at most two, one for foreground and one for background) and attributes (as many as you want), separated by spaces. + The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` and `white`. The first color given is the foreground; the second is the background. + Colors may also be given as numbers between 0 and 255; these use ANSI 256-color mode (but note that not all terminals may support this). If your terminal supports it, you may also specify 24-bit RGB values as hex, like `#ff0ab3`. + The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`, `italic`, and `strike` (for crossed-out or "strikethrough" letters). The position of any attributes with respect to the colors (before, after, or in between), doesn't matter. Specific attributes may be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`, `no-ul`, etc). + An empty color string produces no color effect at all. This can be used to avoid coloring specific elements without disabling color entirely. + For git's pre-defined color slots, the attributes are meant to be reset at the beginning of each item in the colored output. So setting `color.decorate.branch` to `black` will paint that branch name in a plain `black`, even if the previous thing on the same output line (e.g. opening parenthesis before the list of branch names in `log --decorate` output) is set to be painted with `bold` or some other attribute. However, custom log formats may do more complicated and layered coloring, and the negated forms may be useful there. pathname:: A variable that takes a pathname value can be given a string that begins with "`~/`" or "`~user/`", and the usual tilde expansion happens to such a string: `~/` is expanded to the value of `$HOME`, and `~user/` to the specified user's home directory. Variables ~~~~~~~~~ Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. Other git-related tools may and do use their own variables. When inventing new variables for use in your own tool, make sure their names do not conflict with those that are used by Git itself and other popular tools, and describe them in your documentation. advice.*:: These variables control various optional help messages designed to aid new users. All 'advice.*' variables default to 'true', and you can tell Git that you do not need help by setting these to 'false': + -- pushUpdateRejected:: Set this variable to 'false' if you want to disable 'pushNonFFCurrent', 'pushNonFFMatching', 'pushAlreadyExists', 'pushFetchFirst', and 'pushNeedsForce' simultaneously. pushNonFFCurrent:: Advice shown when linkgit:git-push[1] fails due to a non-fast-forward update to the current branch. pushNonFFMatching:: Advice shown when you ran linkgit:git-push[1] and pushed 'matching refs' explicitly (i.e. you used ':', or specified a refspec that isn't your current branch) and it resulted in a non-fast-forward error. pushAlreadyExists:: Shown when linkgit:git-push[1] rejects an update that does not qualify for fast-forwarding (e.g., a tag.) pushFetchFirst:: Shown when linkgit:git-push[1] rejects an update that tries to overwrite a remote ref that points at an object we do not have. pushNeedsForce:: Shown when linkgit:git-push[1] rejects an update that tries to overwrite a remote ref that points at an object that is not a commit-ish, or make the remote ref point at an object that is not a commit-ish. statusHints:: Show directions on how to proceed from the current state in the output of linkgit:git-status[1], in the template shown when writing commit messages in linkgit:git-commit[1], and in the help message shown by linkgit:git-checkout[1] when switching branch. statusUoption:: Advise to consider using the `-u` option to linkgit:git-status[1] when the command takes more than 2 seconds to enumerate untracked files. commitBeforeMerge:: Advice shown when linkgit:git-merge[1] refuses to merge to avoid overwriting local changes. resolveConflict:: Advice shown by various commands when conflicts prevent the operation from being performed. implicitIdentity:: Advice on how to set your identity configuration when your information is guessed from the system username and domain name. detachedHead:: Advice shown when you used linkgit:git-checkout[1] to move to the detach HEAD state, to instruct how to create a local branch after the fact. checkoutAmbiguousRemoteBranchName:: Advice shown when the argument to linkgit:git-checkout[1] ambiguously resolves to a remote tracking branch on more than one remote in situations where an unambiguous argument would have otherwise caused a remote-tracking branch to be checked out. See the `checkout.defaultRemote` configuration variable for how to set a given remote to used by default in some situations where this advice would be printed. amWorkDir:: Advice that shows the location of the patch file when linkgit:git-am[1] fails to apply it. rmHints:: In case of failure in the output of linkgit:git-rm[1], show directions on how to proceed from the current state. addEmbeddedRepo:: Advice on what to do when you've accidentally added one git repo inside of another. ignoredHook:: Advice shown if a hook is ignored because the hook is not set as executable. waitingForEditor:: Print a message to the terminal whenever Git is waiting for editor input from the user. -- core.fileMode:: Tells Git if the executable bit of files in the working tree is to be honored. + Some filesystems lose the executable bit when a file that is marked as executable is checked out, or checks out a non-executable file with executable bit on. linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem to see if it handles the executable bit correctly and this variable is automatically set as necessary. + A repository, however, may be on a filesystem that handles the filemode correctly, and this variable is set to 'true' when created, but later may be made accessible from another environment that loses the filemode (e.g. exporting ext4 via CIFS mount, visiting a Cygwin created repository with Git for Windows or Eclipse). In such a case it may be necessary to set this variable to 'false'. See linkgit:git-update-index[1]. + The default is true (when core.filemode is not specified in the config file). core.hideDotFiles:: (Windows-only) If true, mark newly-created directories and files whose name starts with a dot as hidden. If 'dotGitOnly', only the `.git/` directory is hidden, but no other files starting with a dot. The default mode is 'dotGitOnly'. core.ignoreCase:: Internal variable which enables various workarounds to enable Git to work better on filesystems that are not case sensitive, like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing finds "makefile" when Git expects "Makefile", Git will assume it is really the same file, and continue to remember it as "Makefile". + The default is false, except linkgit:git-clone[1] or linkgit:git-init[1] will probe and set core.ignoreCase true if appropriate when the repository is created. + Git relies on the proper configuration of this variable for your operating and file system. Modifying this value may result in unexpected behavior. core.precomposeUnicode:: This option is only used by Mac OS implementation of Git. When core.precomposeUnicode=true, Git reverts the unicode decomposition of filenames done by Mac OS. This is useful when sharing a repository between Mac OS and Linux or Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When false, file names are handled fully transparent by Git, which is backward compatible with older versions of Git. core.protectHFS:: If set to true, do not allow checkout of paths that would be considered equivalent to `.git` on an HFS+ filesystem. Defaults to `true` on Mac OS, and `false` elsewhere. core.protectNTFS:: If set to true, do not allow checkout of paths that would cause problems with the NTFS filesystem, e.g. conflict with 8.3 "short" names. Defaults to `true` on Windows, and `false` elsewhere. core.fsmonitor:: If set, the value of this variable is used as a command which will identify all files that may have changed since the requested date/time. This information is used to speed up git by avoiding unnecessary processing of files that have not changed. See the "fsmonitor-watchman" section of linkgit:githooks[5]. core.trustctime:: If false, the ctime differences between the index and the working tree are ignored; useful when the inode change time is regularly modified by something outside Git (file system crawlers and some backup systems). See linkgit:git-update-index[1]. True by default. core.splitIndex:: If true, the split-index feature of the index will be used. See linkgit:git-update-index[1]. False by default. core.untrackedCache:: Determines what to do about the untracked cache feature of the index. It will be kept, if this variable is unset or set to `keep`. It will automatically be added if set to `true`. And it will automatically be removed, if set to `false`. Before setting it to `true`, you should check that mtime is working properly on your system. See linkgit:git-update-index[1]. `keep` by default. core.checkStat:: When missing or is set to `default`, many fields in the stat structure are checked to detect if a file has been modified since Git looked at it. When this configuration variable is set to `minimal`, sub-second part of mtime and ctime, the uid and gid of the owner of the file, the inode number (and the device number, if Git was compiled to use it), are excluded from the check among these fields, leaving only the whole-second part of mtime (and ctime, if `core.trustCtime` is set) and the filesize to be checked. + There are implementations of Git that do not leave usable values in some fields (e.g. JGit); by excluding these fields from the comparison, the `minimal` mode may help interoperability when the same repository is used by these other systems at the same time. core.quotePath:: Commands that output paths (e.g. 'ls-files', 'diff'), will quote "unusual" characters in the pathname by enclosing the pathname in double-quotes and escaping those characters with backslashes in the same way C escapes control characters (e.g. `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with values larger than 0x80 (e.g. octal `\302\265` for "micro" in UTF-8). If this variable is set to false, bytes higher than 0x80 are not considered "unusual" any more. Double-quotes, backslash and control characters are always escaped regardless of the setting of this variable. A simple space character is not considered "unusual". Many commands can output pathnames completely verbatim using the `-z` option. The default value is true. core.eol:: Sets the line ending type to use in the working directory for files that have the `text` property set when core.autocrlf is false. Alternatives are 'lf', 'crlf' and 'native', which uses the platform's native line ending. The default value is `native`. See linkgit:gitattributes[5] for more information on end-of-line conversion. core.safecrlf:: If true, makes Git check if converting `CRLF` is reversible when end-of-line conversion is active. Git will verify if a command modifies a file in the work tree either directly or indirectly. For example, committing a file followed by checking out the same file should yield the original file in the work tree. If this is not the case for the current setting of `core.autocrlf`, Git will reject the file. The variable can be set to "warn", in which case Git will only warn about an irreversible conversion but continue the operation. + CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by Git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. + If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell Git that this file is binary and Git will handle the file appropriately. + Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. + Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of `core.eol` and `core.autocrlf`, but only for the current one. For example, a text file with `LF` would be accepted with `core.eol=lf` and could later be checked out with `core.eol=crlf`, in which case the resulting file would contain `CRLF`, although the original file contained `LF`. However, in both work trees the line endings would be consistent, that is either all `LF` or all `CRLF`, but never mixed. A file with mixed line endings would be reported by the `core.safecrlf` mechanism. core.autocrlf:: Setting this variable to "true" is the same as setting the `text` attribute to "auto" on all files and core.eol to "crlf". Set to true if you want to have `CRLF` line endings in your working directory and the repository has LF line endings. This variable can be set to 'input', in which case no output conversion is performed. core.checkRoundtripEncoding:: A comma and/or whitespace separated list of encodings that Git performs UTF-8 round trip checks on if they are used in an `working-tree-encoding` attribute (see linkgit:gitattributes[5]). The default value is `SHIFT-JIS`. core.symlinks:: If false, symbolic links are checked out as small plain files that contain the link text. linkgit:git-update-index[1] and linkgit:git-add[1] will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links. + The default is true, except linkgit:git-clone[1] or linkgit:git-init[1] will probe and set core.symlinks false if appropriate when the repository is created. core.gitProxy:: A "proxy command" to execute (as 'command host port') instead of establishing direct connection to the remote server when using the Git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins. + Can be overridden by the `GIT_PROXY_COMMAND` environment variable (which always applies universally, without the special "for" handling). + The special string `none` can be used as the proxy command to specify that no proxy be used for a given domain pattern. This is useful for excluding servers inside a firewall from proxy use, while defaulting to a common proxy for external domains. core.sshCommand:: If this variable is set, `git fetch` and `git push` will use the specified command instead of `ssh` when they need to connect to a remote system. The command is in the same form as the `GIT_SSH_COMMAND` environment variable and is overridden when the environment variable is set. core.ignoreStat:: If true, Git will avoid using lstat() calls to detect if files have changed by setting the "assume-unchanged" bit for those tracked files which it has updated identically in both the index and working tree. + When files are modified outside of Git, the user will need to stage the modified files explicitly (e.g. see 'Examples' section in linkgit:git-update-index[1]). Git will not normally detect changes to those files. + This is useful on systems where lstat() calls are very slow, such as CIFS/Microsoft Windows. + False by default. core.preferSymlinkRefs:: Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link. core.bare:: If true this repository is assumed to be 'bare' and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as linkgit:git-add[1] or linkgit:git-merge[1]. + This setting is automatically guessed by linkgit:git-clone[1] or linkgit:git-init[1] when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true). core.worktree:: Set the path to the root of the working tree. If `GIT_COMMON_DIR` environment variable is set, core.worktree is ignored and not used for determining the root of working tree. This can be overridden by the `GIT_WORK_TREE` environment variable and the `--work-tree` command-line option. The value can be an absolute path or relative to the path to the .git directory, which is either specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the top level of your working tree. + Note that this variable is honored even when set in a configuration file in a ".git" subdirectory of a directory and its value differs from the latter directory (e.g. "/path/to/.git/config" has core.worktree set to "/different/path"), which is most likely a misconfiguration. Running Git commands in the "/path/to" directory will still use "/different/path" as the root of the work tree and can cause confusion unless you know what you are doing (e.g. you are creating a read-only snapshot of the same index to a location different from the repository's usual working tree). core.logAllRefUpdates:: Enable the reflog. Updates to a ref is logged to the file "`$GIT_DIR/logs/`", by appending the new and old SHA-1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to `true`, missing "`$GIT_DIR/logs/`" file is automatically created for branch heads (i.e. under `refs/heads/`), remote refs (i.e. under `refs/remotes/`), note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`. If it is set to `always`, then a missing reflog is automatically created for any ref under `refs/`. + This information can be used to determine what commit was the tip of a branch "2 days ago". + This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository. core.repositoryFormatVersion:: Internal variable identifying the repository format and layout version. core.sharedRepository:: When 'group' (or 'true'), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When 'all' (or 'world' or 'everybody'), the repository will be readable by all users, additionally to being group-shareable. When 'umask' (or 'false'), Git will use permissions reported by umask(2). When '0xxx', where '0xxx' is an octal number, files in the repository will have this mode value. '0xxx' will override user's umask value (whereas the other options will only override requested parts of the user's umask value). Examples: '0660' will make the repo read/write-able for the owner and group, but inaccessible to others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a repository that is group-readable but not group-writable. See linkgit:git-init[1]. False by default. core.warnAmbiguousRefs:: If true, Git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the repository. True by default. core.compression:: An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a default to other compression variables, such as `core.looseCompression` and `pack.compression`. core.looseCompression:: An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best speed). core.packedGitWindowSize:: Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system's memory manager, but may improve performance when accessing a large number of large pack files. + Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value. + Common unit suffixes of 'k', 'm', or 'g' are supported. core.packedGitLimit:: Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process. + Default is 256 MiB on 32 bit platforms and 32 TiB (effectively unlimited) on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value. + Common unit suffixes of 'k', 'm', or 'g' are supported. core.deltaBaseCacheLimit:: Maximum number of bytes to reserve for caching base objects that may be referenced by multiple deltified objects. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times. + Default is 96 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value. + Common unit suffixes of 'k', 'm', or 'g' are supported. core.bigFileThreshold:: Files larger than this size are stored deflated, without attempting delta compression. Storing large files without delta compression avoids excessive memory usage, at the slight expense of increased disk usage. Additionally files larger than this size are always treated as binary. + Default is 512 MiB on all platforms. This should be reasonable for most projects as source code and other text files can still be delta compressed, but larger binary media files won't be. + Common unit suffixes of 'k', 'm', or 'g' are supported. core.excludesFile:: Specifies the pathname to the file that contains patterns to describe paths that are not meant to be tracked, in addition to '.gitignore' (per-directory) and '.git/info/exclude'. Defaults to `$XDG_CONFIG_HOME/git/ignore`. If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore` is used instead. See linkgit:gitignore[5]. core.askPass:: Some commands (e.g. svn and http interfaces) that interactively ask for a password can be told to use an external program given via the value of this variable. Can be overridden by the `GIT_ASKPASS` environment variable. If not set, fall back to the value of the `SSH_ASKPASS` environment variable or, failing that, a simple password prompt. The external program shall be given a suitable prompt as command-line argument and write the password on its STDOUT. core.attributesFile:: In addition to '.gitattributes' (per-directory) and '.git/info/attributes', Git looks into this file for attributes (see linkgit:gitattributes[5]). Path expansions are made the same way as for `core.excludesFile`. Its default value is `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/attributes` is used instead. core.hooksPath:: By default Git will look for your hooks in the '$GIT_DIR/hooks' directory. Set this to different path, e.g. '/etc/git/hooks', and Git will try to find your hooks in that directory, e.g. '/etc/git/hooks/pre-receive' instead of in '$GIT_DIR/hooks/pre-receive'. + The path can be either absolute or relative. A relative path is taken as relative to the directory where the hooks are run (see the "DESCRIPTION" section of linkgit:githooks[5]). + This configuration variable is useful in cases where you'd like to centrally configure your Git hooks instead of configuring them on a per-repository basis, or as a more flexible and centralized alternative to having an `init.templateDir` where you've changed default hooks. core.editor:: Commands such as `commit` and `tag` that let you edit messages by launching an editor use the value of this variable when it is set, and the environment variable `GIT_EDITOR` is not set. See linkgit:git-var[1]. core.commentChar:: Commands such as `commit` and `tag` that let you edit messages consider a line that begins with this character commented, and removes them after the editor returns (default '#'). + If set to "auto", `git-commit` would select a character that is not the beginning character of any line in existing commit messages. core.filesRefLockTimeout:: The length of time, in milliseconds, to retry when trying to lock an individual reference. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 100 (i.e., retry for 100ms). core.packedRefsTimeout:: The length of time, in milliseconds, to retry when trying to lock the `packed-refs` file. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 1000 (i.e., retry for 1 second). sequence.editor:: Text editor used by `git rebase -i` for editing the rebase instruction file. The value is meant to be interpreted by the shell when it is used. It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable. When not configured the default commit message editor is used instead. core.pager:: Text viewer for use by Git commands (e.g., 'less'). The value is meant to be interpreted by the shell. The order of preference is the `$GIT_PAGER` environment variable, then `core.pager` configuration, then `$PAGER`, and then the default chosen at compile time (usually 'less'). + When the `LESS` environment variable is unset, Git sets it to `FRX` (if `LESS` environment variable is set, Git does not change it at all). If you want to selectively override Git's default setting for `LESS`, you can set `core.pager` to e.g. `less -S`. This will be passed to the shell by Git, which will translate the final command to `LESS=FRX less -S`. The environment does not set the `S` option but the command line does, instructing less to truncate long lines. Similarly, setting `core.pager` to `less -+F` will deactivate the `F` option specified by the environment from the command-line, deactivating the "quit if one screen" behavior of `less`. One can specifically activate some flags for particular commands: for example, setting `pager.blame` to `less -S` enables line truncation only for `git blame`. + Likewise, when the `LV` environment variable is unset, Git sets it to `-c`. You can override this setting by exporting `LV` with another value or setting `core.pager` to `lv +c`. core.whitespace:: A comma separated list of common whitespace problems to notice. 'git diff' will use `color.diff.whitespace` to highlight them, and 'git apply --whitespace=error' will consider them as errors. You can prefix `-` to disable any of them (e.g. `-trailing-space`): + * `blank-at-eol` treats trailing whitespaces at the end of the line as an error (enabled by default). * `space-before-tab` treats a space character that appears immediately before a tab character in the initial indent part of the line as an error (enabled by default). * `indent-with-non-tab` treats a line that is indented with space characters instead of the equivalent tabs as an error (not enabled by default). * `tab-in-indent` treats a tab character in the initial indent part of the line as an error (not enabled by default). * `blank-at-eof` treats blank lines added at the end of file as an error (enabled by default). * `trailing-space` is a short-hand to cover both `blank-at-eol` and `blank-at-eof`. * `cr-at-eol` treats a carriage-return at the end of line as part of the line terminator, i.e. with it, `trailing-space` does not trigger if the character before such a carriage-return is not a whitespace (not enabled by default). * `tabwidth=` tells how many character positions a tab occupies; this is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent` errors. The default tab width is 8. Allowed values are 1 to 63. core.fsyncObjectFiles:: This boolean will enable 'fsync()' when writing object files. + This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback"). core.preloadIndex:: Enable parallel index preload for operations like 'git diff' + This can speed up operations like 'git diff' and 'git status' especially on filesystems like NFS that have weak caching semantics and thus relatively high IO latencies. When enabled, Git will do the index comparison to the filesystem data in parallel, allowing overlapping IO's. Defaults to true. core.createObject:: You can set this to 'link', in which case a hardlink followed by a delete of the source are used to make sure that object creation will not overwrite existing objects. + On some file system/operating system combinations, this is unreliable. Set this config setting to 'rename' there; However, This will remove the check that makes sure that existing object files will not get overwritten. core.notesRef:: When showing commit messages, also show notes which are stored in the given ref. The ref must be fully qualified. If the given ref does not exist, it is not an error but means that no notes should be printed. + This setting defaults to "refs/notes/commits", and it can be overridden by the `GIT_NOTES_REF` environment variable. See linkgit:git-notes[1]. core.commitGraph:: If true, then git will read the commit-graph file (if it exists) to parse the graph structure of commits. Defaults to false. See linkgit:git-commit-graph[1] for more information. core.useReplaceRefs:: If set to `false`, behave as if the `--no-replace-objects` option was given on the command line. See linkgit:git[1] and linkgit:git-replace[1] for more information. core.sparseCheckout:: Enable "sparse checkout" feature. See section "Sparse checkout" in linkgit:git-read-tree[1] for more information. core.abbrev:: Set the length object names are abbreviated to. If unspecified or set to "auto", an appropriate value is computed based on the approximate number of packed objects in your repository, which hopefully is enough for abbreviated object names to stay unique for some time. The minimum length is 4. add.ignoreErrors:: add.ignore-errors (deprecated):: Tells 'git add' to continue adding files when some files cannot be added due to indexing errors. Equivalent to the `--ignore-errors` option of linkgit:git-add[1]. `add.ignore-errors` is deprecated, as it does not follow the usual naming convention for configuration variables. alias.*:: Command aliases for the linkgit:git[1] command wrapper - e.g. after defining "alias.last = cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit HEAD". To avoid confusion and troubles with script usage, aliases that hide existing Git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping is supported. A quote pair or a backslash can be used to quote them. + If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the invocation "git new" is equivalent to running the shell command "gitk --all --not ORIG_HEAD". Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory. `GIT_PREFIX` is set as returned by running 'git rev-parse --show-prefix' from the original current directory. See linkgit:git-rev-parse[1]. am.keepcr:: If true, git-am will call git-mailsplit for patches in mbox format with parameter `--keep-cr`. In this case git-mailsplit will not remove `\r` from lines ending with `\r\n`. Can be overridden by giving `--no-keep-cr` from the command line. See linkgit:git-am[1], linkgit:git-mailsplit[1]. am.threeWay:: By default, `git am` will fail if the patch does not apply cleanly. When set to true, this setting tells `git am` to fall back on 3-way merge if the patch records the identity of blobs it is supposed to apply to and we have those blobs available locally (equivalent to giving the `--3way` option from the command line). Defaults to `false`. See linkgit:git-am[1]. apply.ignoreWhitespace:: When set to 'change', tells 'git apply' to ignore changes in whitespace, in the same way as the `--ignore-space-change` option. When set to one of: no, none, never, false tells 'git apply' to respect all whitespace differences. See linkgit:git-apply[1]. apply.whitespace:: Tells 'git apply' how to handle whitespaces, in the same way as the `--whitespace` option. See linkgit:git-apply[1]. blame.blankBoundary:: Show blank commit object name for boundary commits in linkgit:git-blame[1]. This option defaults to false. blame.coloring:: This determines the coloring scheme to be applied to blame output. It can be 'repeatedLines', 'highlightRecent', or 'none' which is the default. blame.date:: Specifies the format used to output dates in linkgit:git-blame[1]. If unset the iso format is used. For supported values, see the discussion of the `--date` option at linkgit:git-log[1]. blame.showEmail:: Show the author email instead of author name in linkgit:git-blame[1]. This option defaults to false. blame.showRoot:: Do not treat root commits as boundaries in linkgit:git-blame[1]. This option defaults to false. branch.autoSetupMerge:: Tells 'git branch' and 'git checkout' to set up new branches so that linkgit:git-pull[1] will appropriately merge from the starting point branch. Note that even if this option is not set, this behavior can be chosen per-branch using the `--track` and `--no-track` options. The valid settings are: `false` -- no automatic setup is done; `true` -- automatic setup is done when the starting point is a remote-tracking branch; `always` -- automatic setup is done when the starting point is either a local branch or remote-tracking branch. This option defaults to true. branch.autoSetupRebase:: When a new branch is created with 'git branch' or 'git checkout' that tracks another branch, this variable tells Git to set up pull to rebase instead of merge (see "branch..rebase"). When `never`, rebase is never automatically set to true. When `local`, rebase is set to true for tracked branches of other local branches. When `remote`, rebase is set to true for tracked branches of remote-tracking branches. When `always`, rebase will be set to true for all tracking branches. See "branch.autoSetupMerge" for details on how to set up a branch to track another branch. This option defaults to never. branch.sort:: This variable controls the sort ordering of branches when displayed by linkgit:git-branch[1]. Without the "--sort=" option provided, the value of this variable will be used as the default. See linkgit:git-for-each-ref[1] field names for valid values. branch..remote:: When on branch , it tells 'git fetch' and 'git push' which remote to fetch from/push to. The remote to push to may be overridden with `remote.pushDefault` (for all branches). The remote to push to, for the current branch, may be further overridden by `branch..pushRemote`. If no remote is configured, or if you are not on any branch, it defaults to `origin` for fetching and `remote.pushDefault` for pushing. Additionally, `.` (a period) is the current local repository (a dot-repository), see `branch..merge`'s final note below. branch..pushRemote:: When on branch , it overrides `branch..remote` for pushing. It also overrides `remote.pushDefault` for pushing from branch . When you pull from one place (e.g. your upstream) and push to another place (e.g. your own publishing repository), you would want to set `remote.pushDefault` to specify the remote to push to for all branches, and use this option to override it for a specific branch. branch..merge:: Defines, together with branch..remote, the upstream branch for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which branch to merge and can also affect 'git push' (see push.default). When in branch , it tells 'git fetch' the default refspec to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a ref which is fetched from the remote given by "branch..remote". The merge information is used by 'git pull' (which at first calls 'git fetch') to lookup the default branch for merging. Without this option, 'git pull' defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup 'git pull' so that it merges into from another branch in the local repository, you can point branch..merge to the desired branch, and use the relative path setting `.` (a period) for branch..remote. branch..mergeOptions:: Sets default options for merging into branch . The syntax and supported options are the same as those of linkgit:git-merge[1], but option values containing whitespace characters are currently not supported. branch..rebase:: When true, rebase the branch on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "pull.rebase" for doing this in a non branch-specific manner. + When `merges`, pass the `--rebase-merges` option to 'git rebase' so that the local merge commits are included in the rebase (see linkgit:git-rebase[1] for details). + When preserve, also pass `--preserve-merges` along to 'git rebase' so that locally committed merge commits will not be flattened by running 'git pull'. + When the value is `interactive`, the rebase is run in interactive mode. + *NOTE*: this is a possibly dangerous operation; do *not* use it unless you understand the implications (see linkgit:git-rebase[1] for details). branch..description:: Branch description, can be edited with `git branch --edit-description`. Branch description is automatically added in the format-patch cover letter or request-pull summary. browser..cmd:: Specify the command to invoke the specified browser. The specified command is evaluated in shell with the URLs passed as arguments. (See linkgit:git-web{litdd}browse[1].) browser..path:: Override the path for the given tool that may be used to browse HTML help (see `-w` option in linkgit:git-help[1]) or a working repository in gitweb (see linkgit:git-instaweb[1]). checkout.defaultRemote:: When you run 'git checkout ' and only have one remote, it may implicitly fall back on checking out and tracking e.g. 'origin/'. This stops working as soon as you have more than one remote with a '' reference. This setting allows for setting the name of a preferred remote that should always win when it comes to disambiguation. The typical use-case is to set this to `origin`. + Currently this is used by linkgit:git-checkout[1] when 'git checkout ' will checkout the '' branch on another remote, and by linkgit:git-worktree[1] when 'git worktree add' refers to a remote branch. This setting might be used for other checkout-like commands or functionality in the future. clean.requireForce:: A boolean to make git-clean do nothing unless given -f, -i or -n. Defaults to true. color.advice:: A boolean to enable/disable color in hints (e.g. when a push failed, see `advice.*` for a list). May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the error output goes to a terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.advice.hint:: Use customized color for hints. color.blame.highlightRecent:: This can be used to color the metadata of a blame line depending on age of the line. + This setting should be set to a comma-separated list of color and date settings, starting and ending with a color, the dates should be set from oldest to newest. The metadata will be colored given the colors if the the line was introduced before the given timestamp, overwriting older timestamped colors. + Instead of an absolute timestamp relative timestamps work as well, e.g. 2.weeks.ago is valid to address anything older than 2 weeks. + It defaults to 'blue,12 month ago,white,1 month ago,red', which colors everything older than one year blue, recent changes between one month and one year old are kept white, and lines introduced within the last month are colored red. color.blame.repeatedLines:: Use the customized color for the part of git-blame output that is repeated meta information per line (such as commit id, author name, date and timezone). Defaults to cyan. color.branch:: A boolean to enable/disable color in the output of linkgit:git-branch[1]. May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the output is to a terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.branch.:: Use customized color for branch coloration. `` is one of `current` (the current branch), `local` (a local branch), `remote` (a remote-tracking branch in refs/remotes/), `upstream` (upstream tracking branch), `plain` (other refs). color.diff:: Whether to use ANSI escape sequences to add color to patches. If this is set to `always`, linkgit:git-diff[1], linkgit:git-log[1], and linkgit:git-show[1] will use color for all patches. If it is set to `true` or `auto`, those commands will only use color when output is to the terminal. If unset, then the value of `color.ui` is used (`auto` by default). + This does not affect linkgit:git-format-patch[1] or the 'git-diff-{asterisk}' plumbing commands. Can be overridden on the command line with the `--color[=]` option. color.diff.:: Use customized color for diff colorization. `` specifies which part of the patch to use the specified color, and is one of `context` (context text - `plain` is a historical synonym), `meta` (metainformation), `frag` (hunk header), 'func' (function in hunk header), `old` (removed lines), `new` (added lines), `commit` (commit headers), `whitespace` (highlighting whitespace errors), `oldMoved` (deleted lines), `newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`, `oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative` `newMovedAlternativeDimmed` (See the '' setting of '--color-moved' in linkgit:git-diff[1] for details), `contextDimmed`, `oldDimmed`, `newDimmed`, `contextBold`, `oldBold`, and `newBold` (see linkgit:git-range-diff[1] for details). color.decorate.:: Use customized color for 'git log --decorate' output. `` is one of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local branches, remote-tracking branches, tags, stash and HEAD, respectively and `grafted` for grafted commits. color.grep:: When set to `always`, always highlight matches. When `false` (or `never`), never. When set to `true` or `auto`, use color only when the output is written to the terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.grep.:: Use customized color for grep colorization. `` specifies which part of the line to use the specified color, and is one of + -- `context`;; non-matching text in context lines (when using `-A`, `-B`, or `-C`) `filename`;; filename prefix (when not using `-h`) `function`;; function name lines (when using `-p`) `lineNumber`;; line number prefix (when using `-n`) `column`;; column number prefix (when using `--column`) `match`;; matching text (same as setting `matchContext` and `matchSelected`) `matchContext`;; matching text in context lines `matchSelected`;; matching text in selected lines `selected`;; non-matching text in selected lines `separator`;; separators between fields on a line (`:`, `-`, and `=`) and between hunks (`--`) -- color.interactive:: When set to `always`, always use colors for interactive prompts and displays (such as those used by "git-add --interactive" and "git-clean --interactive"). When false (or `never`), never. When set to `true` or `auto`, use colors only when the output is to the terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.interactive.:: Use customized color for 'git add --interactive' and 'git clean --interactive' output. `` may be `prompt`, `header`, `help` or `error`, for four distinct types of normal output from interactive commands. color.pager:: A boolean to enable/disable colored output when the pager is in use (default is true). color.push:: A boolean to enable/disable color in push errors. May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the error output goes to a terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.push.error:: Use customized color for push errors. color.remote:: If set, keywords at the start of the line are highlighted. The keywords are "error", "warning", "hint" and "success", and are matched case-insensitively. May be set to `always`, `false` (or `never`) or `auto` (or `true`). If unset, then the value of `color.ui` is used (`auto` by default). color.remote.:: Use customized color for each remote keyword. `` may be `hint`, `warning`, `success` or `error` which match the corresponding keyword. color.showBranch:: A boolean to enable/disable color in the output of linkgit:git-show-branch[1]. May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the output is to a terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.status:: A boolean to enable/disable color in the output of linkgit:git-status[1]. May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the output is to a terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.status.:: Use customized color for status colorization. `` is one of `header` (the header text of the status message), `added` or `updated` (files which are added but not committed), `changed` (files which are changed but not added in the index), `untracked` (files which are not tracked by Git), `branch` (the current branch), `nobranch` (the color the 'no branch' warning is shown in, defaulting to red), `localBranch` or `remoteBranch` (the local and remote branch names, respectively, when branch and tracking information is displayed in the status short-format), or `unmerged` (files which have unmerged changes). color.transport:: A boolean to enable/disable color when pushes are rejected. May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the error output goes to a terminal. If unset, then the value of `color.ui` is used (`auto` by default). color.transport.rejected:: Use customized color when a push was rejected. color.ui:: This variable determines the default value for variables such as `color.diff` and `color.grep` that control the use of color per command family. Its scope will expand as more commands learn configuration to set a default for the `--color` option. Set it to `false` or `never` if you prefer Git commands not to use color unless enabled explicitly with some other configuration or the `--color` option. Set it to `always` if you want all output not intended for machine consumption to use color, to `true` or `auto` (this is the default since Git 1.8.4) if you want such output to use color when written to the terminal. column.ui:: Specify whether supported commands should output in columns. This variable consists of a list of tokens separated by spaces or commas: + These options control when the feature should be enabled (defaults to 'never'): + -- `always`;; always show in columns `never`;; never show in columns `auto`;; show in columns if the output is to the terminal -- + These options control layout (defaults to 'column'). Setting any of these implies 'always' if none of 'always', 'never', or 'auto' are specified. + -- `column`;; fill columns before rows `row`;; fill rows before columns `plain`;; show in one column -- + Finally, these options can be combined with a layout option (defaults to 'nodense'): + -- `dense`;; make unequal size columns to utilize more space `nodense`;; make equal size columns -- column.branch:: Specify whether to output branch listing in `git branch` in columns. See `column.ui` for details. column.clean:: Specify the layout when list items in `git clean -i`, which always shows files and directories in columns. See `column.ui` for details. column.status:: Specify whether to output untracked files in `git status` in columns. See `column.ui` for details. column.tag:: Specify whether to output tag listing in `git tag` in columns. See `column.ui` for details. commit.cleanup:: This setting overrides the default of the `--cleanup` option in `git commit`. See linkgit:git-commit[1] for details. Changing the default can be useful when you always want to keep lines that begin with comment character `#` in your log message, in which case you would do `git config commit.cleanup whitespace` (note that you will have to remove the help lines that begin with `#` in the commit log template yourself, if you do this). commit.gpgSign:: A boolean to specify whether all commits should be GPG signed. Use of this option when doing operations such as rebase can result in a large number of commits being signed. It may be convenient to use an agent to avoid typing your GPG passphrase several times. commit.status:: A boolean to enable/disable inclusion of status information in the commit message template when using an editor to prepare the commit message. Defaults to true. commit.template:: Specify the pathname of a file to use as the template for new commit messages. commit.verbose:: A boolean or int to specify the level of verbose with `git commit`. See linkgit:git-commit[1]. credential.helper:: Specify an external helper to be called when a username or password credential is needed; the helper may consult external storage to avoid prompting the user for the credentials. Note that multiple helpers may be defined. See linkgit:gitcredentials[7] for details. credential.useHttpPath:: When acquiring credentials, consider the "path" component of an http or https URL to be important. Defaults to false. See linkgit:gitcredentials[7] for more information. credential.username:: If no username is set for a network authentication, use this username by default. See credential..* below, and linkgit:gitcredentials[7]. credential..*:: Any of the credential.* options above can be applied selectively to some credentials. For example "credential.https://example.com.username" would set the default username only for https connections to example.com. See linkgit:gitcredentials[7] for details on how URLs are matched. credentialCache.ignoreSIGHUP:: Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting. completion.commands:: This is only used by git-completion.bash to add or remove commands from the list of completed commands. Normally only porcelain commands and a few select others are completed. You can add more commands, separated by space, in this variable. Prefixing the command with '-' will remove it from the existing list. include::diff-config.txt[] difftool..path:: Override the path for the given tool. This is useful in case your tool is not in the PATH. difftool..cmd:: Specify the command to invoke the specified diff tool. The specified command is evaluated in shell with the following variables available: 'LOCAL' is set to the name of the temporary file containing the contents of the diff pre-image and 'REMOTE' is set to the name of the temporary file containing the contents of the diff post-image. difftool.prompt:: Prompt before each invocation of the diff tool. fastimport.unpackLimit:: If the number of objects imported by linkgit:git-fast-import[1] is below this limit, then the objects will be unpacked into loose object files. However if the number of imported objects equals or exceeds this limit then the pack will be stored as a pack. Storing the pack from a fast-import can make the import operation complete faster, especially on slow filesystems. If not set, the value of `transfer.unpackLimit` is used instead. fetch.recurseSubmodules:: This option can be either set to a boolean value or to 'on-demand'. Setting it to a boolean changes the behavior of fetch and pull to unconditionally recurse into submodules when set to true or to not recurse at all when set to false. When set to 'on-demand' (the default value), fetch and pull will only recurse into a populated submodule when its superproject retrieves a commit that updates the submodule's reference. fetch.fsckObjects:: If it is set to true, git-fetch-pack will check all fetched objects. See `transfer.fsckObjects` for what's checked. Defaults to false. If not set, the value of `transfer.fsckObjects` is used instead. fetch.fsck.:: Acts like `fsck.`, but is used by linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See the `fsck.` documentation for details. fetch.fsck.skipList:: Acts like `fsck.skipList`, but is used by linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See the `fsck.skipList` documentation for details. fetch.unpackLimit:: If the number of objects fetched over the Git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of `transfer.unpackLimit` is used instead. fetch.prune:: If true, fetch will automatically behave as if the `--prune` option was given on the command line. See also `remote..prune` and the PRUNING section of linkgit:git-fetch[1]. fetch.pruneTags:: If true, fetch will automatically behave as if the `refs/tags/*:refs/tags/*` refspec was provided when pruning, if not set already. This allows for setting both this option and `fetch.prune` to maintain a 1=1 mapping to upstream refs. See also `remote..pruneTags` and the PRUNING section of linkgit:git-fetch[1]. fetch.output:: Control how ref update status is printed. Valid values are `full` and `compact`. Default value is `full`. See section OUTPUT in linkgit:git-fetch[1] for detail. fetch.negotiationAlgorithm:: Control how information about the commits in the local repository is sent when negotiating the contents of the packfile to be sent by the server. Set to "skipping" to use an algorithm that skips commits in an effort to converge faster, but may result in a larger-than-necessary packfile; The default is "default" which instructs Git to use the default algorithm that never skips commits (unless the server has acknowledged it or one of its descendants). Unknown values will cause 'git fetch' to error out. + See also the `--negotiation-tip` option for linkgit:git-fetch[1]. format.attach:: Enable multipart/mixed attachments as the default for 'format-patch'. The value can also be a double quoted string which will enable attachments as the default and set the value as the boundary. See the --attach option in linkgit:git-format-patch[1]. format.from:: Provides the default value for the `--from` option to format-patch. Accepts a boolean value, or a name and email address. If false, format-patch defaults to `--no-from`, using commit authors directly in the "From:" field of patch mails. If true, format-patch defaults to `--from`, using your committer identity in the "From:" field of patch mails and including a "From:" field in the body of the patch mail if different. If set to a non-boolean value, format-patch uses that value instead of your committer identity. Defaults to false. format.numbered:: A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto" which enables it only if there is more than one patch. It can be enabled or disabled for all messages by setting it to "true" or "false". See --numbered option in linkgit:git-format-patch[1]. format.headers:: Additional email headers to include in a patch to be submitted by mail. See linkgit:git-format-patch[1]. format.to:: format.cc:: Additional recipients to include in a patch to be submitted by mail. See the --to and --cc options in linkgit:git-format-patch[1]. format.subjectPrefix:: The default for format-patch is to output files with the '[PATCH]' subject prefix. Use this variable to change that prefix. format.signature:: The default for format-patch is to output a signature containing the Git version number. Use this variable to change that default. Set this variable to the empty string ("") to suppress signature generation. format.signatureFile:: Works just like format.signature except the contents of the file specified by this variable will be used as the signature. format.suffix:: The default for format-patch is to output files with the suffix `.patch`. Use this variable to change that suffix (make sure to include the dot if you want it). format.pretty:: The default pretty format for log/show/whatchanged command, See linkgit:git-log[1], linkgit:git-show[1], linkgit:git-whatchanged[1]. format.thread:: The default threading style for 'git format-patch'. Can be a boolean value, or `shallow` or `deep`. `shallow` threading makes every mail a reply to the head of the series, where the head is chosen from the cover letter, the `--in-reply-to`, and the first patch mail, in this order. `deep` threading makes every mail a reply to the previous one. A true boolean value is the same as `shallow`, and a false value disables threading. format.signOff:: A boolean value which lets you enable the `-s/--signoff` option of format-patch by default. *Note:* Adding the Signed-off-by: line to a patch should be a conscious act and means that you certify you have the rights to submit this work under the same open source license. Please see the 'SubmittingPatches' document for further discussion. format.coverLetter:: A boolean that controls whether to generate a cover-letter when format-patch is invoked, but in addition can be set to "auto", to generate a cover-letter only when there's more than one patch. format.outputDirectory:: Set a custom directory to store the resulting files instead of the current working directory. format.useAutoBase:: A boolean value which lets you enable the `--base=auto` option of format-patch by default. filter..clean:: The command which is used to convert the content of a worktree file to a blob upon checkin. See linkgit:gitattributes[5] for details. filter..smudge:: The command which is used to convert the content of a blob object to a worktree file upon checkout. See linkgit:gitattributes[5] for details. fsck.:: During fsck git may find issues with legacy data which wouldn't be generated by current versions of git, and which wouldn't be sent over the wire if `transfer.fsckObjects` was set. This feature is intended to support working with legacy repositories containing such data. + Setting `fsck.` will be picked up by linkgit:git-fsck[1], but to accept pushes of such data set `receive.fsck.` instead, or to clone or fetch it set `fetch.fsck.`. + The rest of the documentation discusses `fsck.*` for brevity, but the same applies for the corresponding `receive.fsck.*` and `fetch..*`. variables. + Unlike variables like `color.ui` and `core.editor` the `receive.fsck.` and `fetch.fsck.` variables will not fall back on the `fsck.` configuration if they aren't set. To uniformly configure the same fsck settings in different circumstances all three of them they must all set to the same values. + When `fsck.` is set, errors can be switched to warnings and vice versa by configuring the `fsck.` setting where the `` is the fsck message ID and the value is one of `error`, `warn` or `ignore`. For convenience, fsck prefixes the error/warning with the message ID, e.g. "missingEmail: invalid author/committer line - missing email" means that setting `fsck.missingEmail = ignore` will hide that issue. + In general, it is better to enumerate existing objects with problems with `fsck.skipList`, instead of listing the kind of breakages these problematic objects share to be ignored, as doing the latter will allow new instances of the same breakages go unnoticed. + Setting an unknown `fsck.` value will cause fsck to die, but doing the same for `receive.fsck.` and `fetch.fsck.` will only cause git to warn. fsck.skipList:: The path to a sorted list of object names (i.e. one SHA-1 per line) that are known to be broken in a non-fatal way and should be ignored. This feature is useful when an established project should be accepted despite early commits containing errors that can be safely ignored such as invalid committer email addresses. Note: corrupt objects cannot be skipped with this setting. + Like `fsck.` this variable has corresponding `receive.fsck.skipList` and `fetch.fsck.skipList` variants. + Unlike variables like `color.ui` and `core.editor` the `receive.fsck.skipList` and `fetch.fsck.skipList` variables will not fall back on the `fsck.skipList` configuration if they aren't set. To uniformly configure the same fsck settings in different circumstances all three of them they must all set to the same values. gc.aggressiveDepth:: The depth parameter used in the delta compression algorithm used by 'git gc --aggressive'. This defaults to 50. gc.aggressiveWindow:: The window size parameter used in the delta compression algorithm used by 'git gc --aggressive'. This defaults to 250. gc.auto:: When there are approximately more than this many loose objects in the repository, `git gc --auto` will pack them. Some Porcelain commands use this command to perform a light-weight garbage collection from time to time. The default value is 6700. Setting this to 0 disables it. gc.autoPackLimit:: When there are more than this many packs that are not marked with `*.keep` file in the repository, `git gc --auto` consolidates them into one larger pack. The default value is 50. Setting this to 0 disables it. gc.autoDetach:: Make `git gc --auto` return immediately and run in background if the system supports it. Default is true. gc.bigPackThreshold:: If non-zero, all packs larger than this limit are kept when `git gc` is run. This is very similar to `--keep-base-pack` except that all packs that meet the threshold are kept, not just the base pack. Defaults to zero. Common unit suffixes of 'k', 'm', or 'g' are supported. + Note that if the number of kept packs is more than gc.autoPackLimit, this configuration variable is ignored, all packs except the base pack will be repacked. After this the number of packs should go below gc.autoPackLimit and gc.bigPackThreshold should be respected again. gc.writeCommitGraph:: If true, then gc will rewrite the commit-graph file when linkgit:git-gc[1] is run. When using linkgit:git-gc[1] '--auto' the commit-graph will be updated if housekeeping is required. Default is false. See linkgit:git-commit-graph[1] for details. gc.logExpiry:: If the file gc.log exists, then `git gc --auto` won't run unless that file is more than 'gc.logExpiry' old. Default is "1.day". See `gc.pruneExpire` for more ways to specify its value. gc.packRefs:: Running `git pack-refs` in a repository renders it unclonable by Git versions prior to 1.5.1.2 over dumb transports such as HTTP. This variable determines whether 'git gc' runs `git pack-refs`. This can be set to `notbare` to enable it within all non-bare repos or it can be set to a boolean value. The default is `true`. gc.pruneExpire:: When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'. Override the grace period with this config variable. The value "now" may be used to disable this grace period and always prune unreachable objects immediately, or "never" may be used to suppress pruning. This feature helps prevent corruption when 'git gc' runs concurrently with another process writing to the repository; see the "NOTES" section of linkgit:git-gc[1]. gc.worktreePruneExpire:: When 'git gc' is run, it calls 'git worktree prune --expire 3.months.ago'. This config variable can be used to set a different grace period. The value "now" may be used to disable the grace period and prune `$GIT_DIR/worktrees` immediately, or "never" may be used to suppress pruning. gc.reflogExpire:: gc..reflogExpire:: 'git reflog expire' removes reflog entries older than this time; defaults to 90 days. The value "now" expires all entries immediately, and "never" suppresses expiration altogether. With "" (e.g. "refs/stash") in the middle the setting applies only to the refs that match the . gc.reflogExpireUnreachable:: gc..reflogExpireUnreachable:: 'git reflog expire' removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days. The value "now" expires all entries immediately, and "never" suppresses expiration altogether. With "" (e.g. "refs/stash") in the middle, the setting applies only to the refs that match the . gc.rerereResolved:: Records of conflicted merge you resolved earlier are kept for this many days when 'git rerere gc' is run. You can also use more human-readable "1.month.ago", etc. The default is 60 days. See linkgit:git-rerere[1]. gc.rerereUnresolved:: Records of conflicted merge you have not resolved are kept for this many days when 'git rerere gc' is run. You can also use more human-readable "1.month.ago", etc. The default is 15 days. See linkgit:git-rerere[1]. gitcvs.commitMsgAnnotation:: Append this string to each commit message. Set to empty string to disable this feature. Defaults to "via git-CVS emulator". gitcvs.enabled:: Whether the CVS server interface is enabled for this repository. See linkgit:git-cvsserver[1]. gitcvs.logFile:: Path to a log file where the CVS server interface well... logs various stuff. See linkgit:git-cvsserver[1]. gitcvs.usecrlfattr:: If true, the server will look up the end-of-line conversion attributes for files to determine the `-k` modes to use. If the attributes force Git to treat a file as text, the `-k` mode will be left blank so CVS clients will treat it as text. If they suppress text conversion, the file will be set with '-kb' mode, which suppresses any newline munging the client might otherwise do. If the attributes do not allow the file type to be determined, then `gitcvs.allBinary` is used. See linkgit:gitattributes[5]. gitcvs.allBinary:: This is used if `gitcvs.usecrlfattr` does not resolve the correct '-kb' mode to use. If true, all unresolved files are sent to the client in mode '-kb'. This causes the client to treat them as binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is set to "guess", then the contents of the file are examined to decide if it is binary, similar to `core.autocrlf`. gitcvs.dbName:: Database used by git-cvsserver to cache revision information derived from the Git repository. The exact meaning depends on the used database driver, for SQLite (which is the default driver) this is a filename. Supports variable substitution (see linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`). Default: '%Ggitcvs.%m.sqlite' gitcvs.dbDriver:: Used Perl DBI driver. You can specify any available driver for this here, but it might not work. git-cvsserver is tested with 'DBD::SQLite', reported to work with 'DBD::Pg', and reported *not* to work with 'DBD::mysql'. Experimental feature. May not contain double colons (`:`). Default: 'SQLite'. See linkgit:git-cvsserver[1]. gitcvs.dbUser, gitcvs.dbPass:: Database user and password. Only useful if setting `gitcvs.dbDriver`, since SQLite has no concept of database users and/or passwords. 'gitcvs.dbUser' supports variable substitution (see linkgit:git-cvsserver[1] for details). gitcvs.dbTableNamePrefix:: Database table name prefix. Prepended to the names of any database tables used, allowing a single database to be used for several repositories. Supports variable substitution (see linkgit:git-cvsserver[1] for details). Any non-alphabetic characters will be replaced with underscores. All gitcvs variables except for `gitcvs.usecrlfattr` and `gitcvs.allBinary` can also be specified as 'gitcvs..' (where 'access_method' is one of "ext" and "pserver") to make them apply only for the given access method. gitweb.category:: gitweb.description:: gitweb.owner:: gitweb.url:: See linkgit:gitweb[1] for description. gitweb.avatar:: gitweb.blame:: gitweb.grep:: gitweb.highlight:: gitweb.patches:: gitweb.pickaxe:: gitweb.remote_heads:: gitweb.showSizes:: gitweb.snapshot:: See linkgit:gitweb.conf[5] for description. grep.lineNumber:: If set to true, enable `-n` option by default. grep.column:: If set to true, enable the `--column` option by default. grep.patternType:: Set the default matching behavior. Using a value of 'basic', 'extended', 'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`, `--fixed-strings`, or `--perl-regexp` option accordingly, while the value 'default' will return to the default matching behavior. grep.extendedRegexp:: If set to true, enable `--extended-regexp` option by default. This option is ignored when the `grep.patternType` option is set to a value other than 'default'. grep.threads:: Number of grep worker threads to use. See `grep.threads` in linkgit:git-grep[1] for more information. grep.fallbackToNoIndex:: If set to true, fall back to git grep --no-index if git grep is executed outside of a git repository. Defaults to false. gpg.program:: Use this custom program instead of "`gpg`" found on `$PATH` when making or verifying a PGP signature. The program must support the same command-line interface as GPG, namely, to verify a detached signature, "`gpg --verify $file - <$signature`" is run, and the program is expected to signal a good signature by exiting with code 0, and to generate an ASCII-armored detached signature, the standard input of "`gpg -bsau $key`" is fed with the contents to be signed, and the program is expected to send the result to its standard output. gpg.format:: Specifies which key format to use when signing with `--gpg-sign`. Default is "openpgp" and another possible value is "x509". gpg..program:: Use this to customize the program used for the signing format you chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still be used as a legacy synonym for `gpg.openpgp.program`. The default value for `gpg.x509.program` is "gpgsm". gui.commitMsgWidth:: Defines how wide the commit message window is in the linkgit:git-gui[1]. "75" is the default. gui.diffContext:: Specifies how many context lines should be used in calls to diff made by the linkgit:git-gui[1]. The default is "5". gui.displayUntracked:: Determines if linkgit:git-gui[1] shows untracked files in the file list. The default is "true". gui.encoding:: Specifies the default encoding to use for displaying of file contents in linkgit:git-gui[1] and linkgit:gitk[1]. It can be overridden by setting the 'encoding' attribute for relevant files (see linkgit:gitattributes[5]). If this option is not set, the tools default to the locale encoding. gui.matchTrackingBranch:: Determines if new branches created with linkgit:git-gui[1] should default to tracking remote branches with matching names or not. Default: "false". gui.newBranchTemplate:: Is used as suggested name when creating new branches using the linkgit:git-gui[1]. gui.pruneDuringFetch:: "true" if linkgit:git-gui[1] should prune remote-tracking branches when performing a fetch. The default value is "false". gui.trustmtime:: Determines if linkgit:git-gui[1] should trust the file modification timestamp or not. By default the timestamps are not trusted. gui.spellingDictionary:: Specifies the dictionary used for spell checking commit messages in the linkgit:git-gui[1]. When set to "none" spell checking is turned off. gui.fastCopyBlame:: If true, 'git gui blame' uses `-C` instead of `-C -C` for original location detection. It makes blame significantly faster on huge repositories at the expense of less thorough copy detection. gui.copyBlameThreshold:: Specifies the threshold to use in 'git gui blame' original location detection, measured in alphanumeric characters. See the linkgit:git-blame[1] manual for more information on copy detection. gui.blamehistoryctx:: Specifies the radius of history context in days to show in linkgit:gitk[1] for the selected commit, when the `Show History Context` menu item is invoked from 'git gui blame'. If this variable is set to zero, the whole history is shown. guitool..cmd:: Specifies the shell command line to execute when the corresponding item of the linkgit:git-gui[1] `Tools` menu is invoked. This option is mandatory for every tool. The command is executed from the root of the working directory, and in the environment it receives the name of the tool as `GIT_GUITOOL`, the name of the currently selected file as 'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if the head is detached, 'CUR_BRANCH' is empty). guitool..needsFile:: Run the tool only if a diff is selected in the GUI. It guarantees that 'FILENAME' is not empty. guitool..noConsole:: Run the command silently, without creating a window to display its output. guitool..noRescan:: Don't rescan the working directory for changes after the tool finishes execution. guitool..confirm:: Show a confirmation dialog before actually running the tool. guitool..argPrompt:: Request a string argument from the user, and pass it to the tool through the `ARGS` environment variable. Since requesting an argument implies confirmation, the 'confirm' option has no effect if this is enabled. If the option is set to 'true', 'yes', or '1', the dialog uses a built-in generic prompt; otherwise the exact value of the variable is used. guitool..revPrompt:: Request a single valid revision from the user, and set the `REVISION` environment variable. In other aspects this option is similar to 'argPrompt', and can be used together with it. guitool..revUnmerged:: Show only unmerged branches in the 'revPrompt' subdialog. This is useful for tools similar to merge or rebase, but not for things like checkout or reset. guitool..title:: Specifies the title to use for the prompt dialog. The default is the tool name. guitool..prompt:: Specifies the general prompt string to display at the top of the dialog, before subsections for 'argPrompt' and 'revPrompt'. The default value includes the actual command. help.browser:: Specify the browser that will be used to display help in the 'web' format. See linkgit:git-help[1]. help.format:: Override the default help format used by linkgit:git-help[1]. Values 'man', 'info', 'web' and 'html' are supported. 'man' is the default. 'web' and 'html' are the same. help.autoCorrect:: Automatically correct and execute mistyped commands after waiting for the given number of deciseconds (0.1 sec). If more than one command can be deduced from the entered text, nothing will be executed. If the value of this option is negative, the corrected command will be executed immediately. If the value is 0 - the command will be just shown but not executed. This is the default. help.htmlPath:: Specify the path where the HTML documentation resides. File system paths and URLs are supported. HTML pages will be prefixed with this path when help is displayed in the 'web' format. This defaults to the documentation path of your Git installation. http.proxy:: Override the HTTP proxy, normally configured using the 'http_proxy', 'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In addition to the syntax understood by curl, it is possible to specify a proxy string with a user name but no password, in which case git will attempt to acquire one in the same way it does for other credentials. See linkgit:gitcredentials[7] for more information. The syntax thus is '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden on a per-remote basis; see remote..proxy http.proxyAuthMethod:: Set the method with which to authenticate against the HTTP proxy. This only takes effect if the configured proxy string contains a user name part (i.e. is of the form 'user@host' or 'user@host:port'). This can be overridden on a per-remote basis; see `remote..proxyAuthMethod`. Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment variable. Possible values are: + -- * `anyauth` - Automatically pick a suitable authentication method. It is assumed that the proxy answers an unauthenticated request with a 407 status code and one or more Proxy-authenticate headers with supported authentication methods. This is the default. * `basic` - HTTP Basic authentication * `digest` - HTTP Digest authentication; this prevents the password from being transmitted to the proxy in clear text * `negotiate` - GSS-Negotiate authentication (compare the --negotiate option of `curl(1)`) * `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`) -- http.emptyAuth:: Attempt authentication without seeking a username or password. This can be used to attempt GSS-Negotiate authentication without specifying a username in the URL, as libcurl normally requires a username for authentication. http.delegation:: Control GSSAPI credential delegation. The delegation is disabled by default in libcurl since version 7.21.7. Set parameter to tell the server what it is allowed to delegate when it comes to user credentials. Used with GSS/kerberos. Possible values are: + -- * `none` - Don't allow any delegation. * `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the Kerberos service ticket, which is a matter of realm policy. * `always` - Unconditionally allow the server to delegate. -- http.extraHeader:: Pass an additional HTTP header when communicating with a server. If more than one such entry exists, all of them are added as extra headers. To allow overriding the settings inherited from the system config, an empty value will reset the extra headers to the empty list. http.cookieFile:: The pathname of a file containing previously stored cookie lines, which should be used in the Git http session, if they match the server. The file format of the file to read cookies from should be plain HTTP headers or the Netscape/Mozilla cookie file format (see `curl(1)`). NOTE that the file specified with http.cookieFile is used only as input unless http.saveCookies is set. http.saveCookies:: If set, store cookies received during requests to the file specified by http.cookieFile. Has no effect if http.cookieFile is unset. http.sslVersion:: The SSL version to use when negotiating an SSL connection, if you want to force the default. The available and default version depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl documentation for more details on the format of this option and for the ssl version supported. Actually the possible values of this option are: - sslv2 - sslv3 - tlsv1 - tlsv1.0 - tlsv1.1 - tlsv1.2 - tlsv1.3 + Can be overridden by the `GIT_SSL_VERSION` environment variable. To force git to use libcurl's default ssl version and ignore any explicit http.sslversion option, set `GIT_SSL_VERSION` to the empty string. http.sslCipherList:: A list of SSL ciphers to use when negotiating an SSL connection. The available ciphers depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the 'CURLOPT_SSL_CIPHER_LIST' option; see the libcurl documentation for more details on the format of this list. + Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable. To force git to use libcurl's default cipher list and ignore any explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the empty string. http.sslVerify:: Whether to verify the SSL certificate when fetching or pushing over HTTPS. Defaults to true. Can be overridden by the `GIT_SSL_NO_VERIFY` environment variable. http.sslCert:: File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment variable. http.sslKey:: File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment variable. http.sslCertPasswordProtected:: Enable Git's password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable. http.sslCAInfo:: File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the `GIT_SSL_CAINFO` environment variable. http.sslCAPath:: Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the `GIT_SSL_CAPATH` environment variable. http.pinnedpubkey:: Public key of the https service. It may either be the filename of a PEM or DER encoded public key file or a string starting with 'sha256//' followed by the base64 encoded sha256 hash of the public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will exit with an error if this option is set but not supported by cURL. http.sslTry:: Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular FTP protocol. This might be needed if the FTP server requires it for security reasons or you wish to connect securely whenever remote FTP server supports it. Default is false since it might trigger certificate verification errors on misconfigured servers. http.maxRequests:: How many HTTP requests to launch in parallel. Can be overridden by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5. http.minSessions:: The number of curl sessions (counted across slots) to be kept across requests. They will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1. http.postBuffer:: Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests. http.lowSpeedLimit, http.lowSpeedTime:: If the HTTP transfer speed is less than 'http.lowSpeedLimit' for longer than 'http.lowSpeedTime' seconds, the transfer is aborted. Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and `GIT_HTTP_LOW_SPEED_TIME` environment variables. http.noEPSV:: A boolean which disables using of EPSV ftp command by curl. This can helpful with some "poor" ftp servers which don't support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV` environment variable. Default is false (curl will use EPSV). http.userAgent:: The HTTP USER_AGENT string presented to an HTTP server. The default value represents the version of the client Git such as git/1.7.1. This option allows you to override this value to a more common value such as Mozilla/4.0. This may be necessary, for instance, if connecting through a firewall that restricts HTTP connections to a set of common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable. http.followRedirects:: Whether git should follow HTTP redirects. If set to `true`, git will transparently follow any redirect issued by a server it encounters. If set to `false`, git will treat all redirects as errors. If set to `initial`, git will follow redirects only for the initial request to a remote, but not for subsequent follow-up HTTP requests. Since git uses the redirected URL as the base for the follow-up requests, this is generally sufficient. The default is `initial`. http..*:: Any of the http.* options above can be applied selectively to some URLs. For a config key to match a URL, each element of the config key is compared to that of the URL, in the following order: + -- . Scheme (e.g., `https` in `https://example.com/`). This field must match exactly between the config key and the URL. . Host/domain name (e.g., `example.com` in `https://example.com/`). This field must match between the config key and the URL. It is possible to specify a `*` as part of the host name to match all subdomains at this level. `https://*.example.com/` for example would match `https://foo.example.com/`, but not `https://foo.bar.example.com/`. . Port number (e.g., `8080` in `http://example.com:8080/`). This field must match exactly between the config key and the URL. Omitted port numbers are automatically converted to the correct default for the scheme before matching. . Path (e.g., `repo.git` in `https://example.com/repo.git`). The path field of the config key must match the path field of the URL either exactly or as a prefix of slash-delimited path elements. This means a config key with path `foo/` matches URL path `foo/bar`. A prefix can only match on a slash (`/`) boundary. Longer matches take precedence (so a config key with path `foo/bar` is a better match to URL path `foo/bar` than a config key with just path `foo/`). . User name (e.g., `user` in `https://user@example.com/repo.git`). If the config key has a user name it must match the user name in the URL exactly. If the config key does not have a user name, that config key will match a URL with any user name (including none), but at a lower precedence than a config key with a user name. -- + The list above is ordered by decreasing precedence; a URL that matches a config key's path is preferred to one that matches its user name. For example, if the URL is `https://user@example.com/foo/bar` a config key match of `https://example.com/foo` will be preferred over a config key match of `https://user@example.com`. + All URLs are normalized before attempting any matching (the password part, if embedded in the URL, is always ignored for matching purposes) so that equivalent URLs that are simply spelled differently will match properly. Environment variable settings always override any matches. The URLs that are matched against are those given directly to Git commands. This means any URLs visited as a result of a redirection do not participate in matching. ssh.variant:: By default, Git determines the command line arguments to use based on the basename of the configured SSH command (configured using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or the config setting `core.sshCommand`). If the basename is unrecognized, Git will attempt to detect support of OpenSSH options by first invoking the configured SSH command with the `-G` (print configuration) option and will subsequently use OpenSSH options (if that is successful) or no options besides the host and remote command (if it fails). + The config variable `ssh.variant` can be set to override this detection. Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`, `tortoiseplink`, `simple` (no options except the host and remote command). The default auto-detection can be explicitly requested using the value `auto`. Any other value is treated as `ssh`. This setting can also be overridden via the environment variable `GIT_SSH_VARIANT`. + The current command-line parameters used for each variant are as follows: + -- * `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command * `simple` - [username@]host command * `plink` or `putty` - [-P port] [-4] [-6] [username@]host command * `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command -- + Except for the `simple` variant, command-line parameters are likely to change as git gains new features. i18n.commitEncoding:: Character encoding the commit messages are stored in; Git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly at other places in the future or in other porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'. i18n.logOutputEncoding:: Character encoding the commit messages are converted to when running 'git log' and friends. imap:: The configuration variables in the 'imap' section are described in linkgit:git-imap-send[1]. index.version:: Specify the version with which new index files should be initialized. This does not affect existing repositories. init.templateDir:: Specify the directory from which templates will be copied. (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].) instaweb.browser:: Specify the program that will be used to browse your working repository in gitweb. See linkgit:git-instaweb[1]. instaweb.httpd:: The HTTP daemon command-line to start gitweb on your working repository. See linkgit:git-instaweb[1]. instaweb.local:: If true the web server started by linkgit:git-instaweb[1] will be bound to the local IP (127.0.0.1). instaweb.modulePath:: The default module path for linkgit:git-instaweb[1] to use instead of /usr/lib/apache2/modules. Only used if httpd is Apache. instaweb.port:: The port number to bind the gitweb httpd to. See linkgit:git-instaweb[1]. interactive.singleKey:: In interactive commands, allow the user to provide one-letter input with a single key (i.e., without hitting enter). Currently this is used by the `--patch` mode of linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1], linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this setting is silently ignored if portable keystroke input is not available; requires the Perl module Term::ReadKey. interactive.diffFilter:: When an interactive command (such as `git add --patch`) shows a colorized diff, git will pipe the diff through the shell command defined by this configuration variable. The command may mark up the diff further for human consumption, provided that it retains a one-to-one correspondence with the lines in the original diff. Defaults to disabled (no filtering). log.abbrevCommit:: If true, makes linkgit:git-log[1], linkgit:git-show[1], and linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may override this option with `--no-abbrev-commit`. log.date:: Set the default date-time mode for the 'log' command. Setting a value for log.date is similar to using 'git log''s `--date` option. See linkgit:git-log[1] for details. log.decorate:: Print out the ref names of any commits that are shown by the log command. If 'short' is specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is specified, the full ref name (including prefix) will be printed. If 'auto' is specified, then if the output is going to a terminal, the ref names are shown as if 'short' were given, otherwise no ref names are shown. This is the same as the `--decorate` option of the `git log`. log.follow:: If `true`, `git log` will act as if the `--follow` option was used when a single is given. This has the same limitations as `--follow`, i.e. it cannot be used to follow multiple files and does not work well on non-linear history. log.graphColors:: A list of colors, separated by commas, that can be used to draw history lines in `git log --graph`. log.showRoot:: If true, the initial commit will be shown as a big creation event. This is equivalent to a diff against an empty tree. Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which normally hide the root commit will now show it. True by default. log.showSignature:: If true, makes linkgit:git-log[1], linkgit:git-show[1], and linkgit:git-whatchanged[1] assume `--show-signature`. log.mailmap:: If true, makes linkgit:git-log[1], linkgit:git-show[1], and linkgit:git-whatchanged[1] assume `--use-mailmap`. mailinfo.scissors:: If true, makes linkgit:git-mailinfo[1] (and therefore linkgit:git-am[1]) act by default as if the --scissors option was provided on the command-line. When active, this features removes everything from the message body before a scissors line (i.e. consisting mainly of ">8", "8<" and "-"). mailmap.file:: The location of an augmenting mailmap file. The default mailmap, located in the root of the repository, is loaded first, then the mailmap file pointed to by this variable. The location of the mailmap file may be in a repository subdirectory, or somewhere outside of the repository itself. See linkgit:git-shortlog[1] and linkgit:git-blame[1]. mailmap.blob:: Like `mailmap.file`, but consider the value as a reference to a blob in the repository. If both `mailmap.file` and `mailmap.blob` are given, both are parsed, with entries from `mailmap.file` taking precedence. In a bare repository, this defaults to `HEAD:.mailmap`. In a non-bare repository, it defaults to empty. man.viewer:: Specify the programs that may be used to display help in the 'man' format. See linkgit:git-help[1]. man..cmd:: Specify the command to invoke the specified man viewer. The specified command is evaluated in shell with the man page passed as argument. (See linkgit:git-help[1].) man..path:: Override the path for the given tool that may be used to display help in the 'man' format. See linkgit:git-help[1]. include::merge-config.txt[] mergetool..path:: Override the path for the given tool. This is useful in case your tool is not in the PATH. mergetool..cmd:: Specify the command to invoke the specified merge tool. The specified command is evaluated in shell with the following variables available: 'BASE' is the name of a temporary file containing the common base of the files to be merged, if available; 'LOCAL' is the name of a temporary file containing the contents of the file on the current branch; 'REMOTE' is the name of a temporary file containing the contents of the file from the branch being merged; 'MERGED' contains the name of the file to which the merge tool should write the results of a successful merge. mergetool..trustExitCode:: For a custom merge command, specify whether the exit code of the merge command can be used to determine whether the merge was successful. If this is not set to true then the merge target file timestamp is checked and the merge assumed to have been successful if the file has been updated, otherwise the user is prompted to indicate the success of the merge. mergetool.meld.hasOutput:: Older versions of `meld` do not support the `--output` option. Git will attempt to detect whether `meld` supports `--output` by inspecting the output of `meld --help`. Configuring `mergetool.meld.hasOutput` will make Git skip these checks and use the configured value instead. Setting `mergetool.meld.hasOutput` to `true` tells Git to unconditionally use the `--output` option, and `false` avoids using `--output`. mergetool.keepBackup:: After performing a merge, the original file with conflict markers can be saved as a file with a `.orig` extension. If this variable is set to `false` then this file is not preserved. Defaults to `true` (i.e. keep the backup files). mergetool.keepTemporaries:: When invoking a custom merge tool, Git uses a set of temporary files to pass to the tool. If the tool returns an error and this variable is set to `true`, then these temporary files will be preserved, otherwise they will be removed after the tool has exited. Defaults to `false`. mergetool.writeToTemp:: Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of conflicting files in the worktree by default. Git will attempt to use a temporary directory for these files when set `true`. Defaults to `false`. mergetool.prompt:: Prompt before each invocation of the merge resolution program. notes.mergeStrategy:: Which merge strategy to choose by default when resolving notes conflicts. Must be one of `manual`, `ours`, `theirs`, `union`, or `cat_sort_uniq`. Defaults to `manual`. See "NOTES MERGE STRATEGIES" section of linkgit:git-notes[1] for more information on each strategy. notes..mergeStrategy:: Which merge strategy to choose when doing a notes merge into refs/notes/. This overrides the more general "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in linkgit:git-notes[1] for more information on the available strategies. notes.displayRef:: The (fully qualified) refname from which to show notes when showing commit messages. The value of this variable can be set to a glob, in which case notes from all matching refs will be shown. You may also specify this configuration variable several times. A warning will be issued for refs that do not exist, but a glob that does not match any refs is silently ignored. + This setting can be overridden with the `GIT_NOTES_DISPLAY_REF` environment variable, which must be a colon separated list of refs or globs. + The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also implicitly added to the list of refs to be displayed. notes.rewrite.:: When rewriting commits with (currently `amend` or `rebase`) and this variable is set to `true`, Git automatically copies your notes from the original to the rewritten commit. Defaults to `true`, but see "notes.rewriteRef" below. notes.rewriteMode:: When copying notes during a rewrite (see the "notes.rewrite." option), determines what to do if the target commit already has a note. Must be one of `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`. Defaults to `concatenate`. + This setting can be overridden with the `GIT_NOTES_REWRITE_MODE` environment variable. notes.rewriteRef:: When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be copied. The ref may be a glob, in which case notes in all matching refs will be copied. You may also specify this configuration several times. + Does not have a default value; you must configure this variable to enable note rewriting. Set it to `refs/notes/commits` to enable rewriting for the default commit notes. + This setting can be overridden with the `GIT_NOTES_REWRITE_REF` environment variable, which must be a colon separated list of refs or globs. pack.window:: The size of the window used by linkgit:git-pack-objects[1] when no window size is given on the command line. Defaults to 10. pack.depth:: The maximum delta depth used by linkgit:git-pack-objects[1] when no maximum depth is given on the command line. Defaults to 50. Maximum value is 4095. pack.windowMemory:: The maximum size of memory that is consumed by each thread in linkgit:git-pack-objects[1] for pack window memory when no limit is given on the command line. The value can be suffixed with "k", "m", or "g". When left unconfigured (or set explicitly to 0), there will be no limit. pack.compression:: An integer -1..9, indicating the compression level for objects in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to -1, the zlib default, which is "a default compromise between speed and compression (currently equivalent to level 6)." + Note that changing the compression level will not automatically recompress all existing objects. You can force recompression by passing the -F option to linkgit:git-repack[1]. pack.deltaCacheSize:: The maximum memory in bytes used for caching deltas in linkgit:git-pack-objects[1] before writing them out to a pack. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Repacking large repositories on machines which are tight with memory might be badly impacted by this though, especially if this cache pushes the system into swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to virtually disable this cache. Defaults to 256 MiB. pack.deltaCacheLimit:: The maximum size of a delta, that is cached in linkgit:git-pack-objects[1]. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Defaults to 1000. Maximum value is 65535. pack.threads:: Specifies the number of threads to spawn when searching for best delta matches. This requires that linkgit:git-pack-objects[1] be compiled with pthreads otherwise this option is ignored with a warning. This is meant to reduce packing time on multiprocessor machines. The required amount of memory for the delta search window is however multiplied by the number of threads. Specifying 0 will cause Git to auto-detect the number of CPU's and set the number of threads accordingly. pack.indexVersion:: Specify the default pack index version. Valid values are 1 for legacy pack index used by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for packs larger than 4 GB as well as proper protection against the repacking of corrupted packs. Version 2 is the default. Note that version 2 is enforced and this config option ignored whenever the corresponding pack is larger than 2 GB. + If you have an old Git that does not understand the version 2 `*.idx` file, cloning or fetching over a non native protocol (e.g. "http") that will copy both `*.pack` file and corresponding `*.idx` file from the other side may give you a repository that cannot be accessed with your older version of Git. If the `*.pack` file is smaller than 2 GB, however, you can use linkgit:git-index-pack[1] on the *.pack file to regenerate the `*.idx` file. pack.packSizeLimit:: The maximum size of a pack. This setting only affects packing to a file when repacking, i.e. the git:// protocol is unaffected. It can be overridden by the `--max-pack-size` option of linkgit:git-repack[1]. Reaching this limit results in the creation of multiple packfiles; which in turn prevents bitmaps from being created. The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit suffixes of 'k', 'm', or 'g' are supported. pack.useBitmaps:: When true, git will use pack bitmaps (if available) when packing to stdout (e.g., during the server side of a fetch). Defaults to true. You should not generally need to turn this off unless you are debugging pack bitmaps. pack.writeBitmaps (deprecated):: This is a deprecated synonym for `repack.writeBitmaps`. pack.writeBitmapHashCache:: When true, git will include a "hash cache" section in the bitmap index (if one is written). This cache can be used to feed git's delta heuristics, potentially leading to better deltas between bitmapped and non-bitmapped objects (e.g., when serving a fetch between an older, bitmapped pack and objects that have been pushed since the last gc). The downside is that it consumes 4 bytes per object of disk space, and that JGit's bitmap implementation does not understand it, causing it to complain if Git and JGit are used on the same repository. Defaults to false. pager.:: If the value is boolean, turns on or off pagination of the output of a particular Git subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand using the pager specified by the value of `pager.`. If `--paginate` or `--no-pager` is specified on the command line, it takes precedence over this option. To disable pagination for all commands, set `core.pager` or `GIT_PAGER` to `cat`. pretty.:: Alias for a --pretty= format string, as specified in linkgit:git-log[1]. Any aliases defined here can be used just as the built-in pretty formats could. For example, running `git config pretty.changelog "format:* %H %s"` would cause the invocation `git log --pretty=changelog` to be equivalent to running `git log "--pretty=format:* %H %s"`. Note that an alias with the same name as a built-in format will be silently ignored. protocol.allow:: If set, provide a user defined default policy for all protocols which don't explicitly have a policy (`protocol..allow`). By default, if unset, known-safe protocols (http, https, git, ssh, file) have a default policy of `always`, known-dangerous protocols (ext) have a default policy of `never`, and all other protocols have a default policy of `user`. Supported policies: + -- * `always` - protocol is always able to be used. * `never` - protocol is never able to be used. * `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is either unset or has a value of 1. This policy should be used when you want a protocol to be directly usable by the user but don't want it used by commands which execute clone/fetch/push commands without user input, e.g. recursive submodule initialization. -- protocol..allow:: Set a policy to be used by protocol `` with clone/fetch/push commands. See `protocol.allow` above for the available policies. + The protocol names currently used by git are: + -- - `file`: any local file-based path (including `file://` URLs, or local paths) - `git`: the anonymous git protocol over a direct TCP connection (or proxy, if configured) - `ssh`: git over ssh (including `host:path` syntax, `ssh://`, etc). - `http`: git over http, both "smart http" and "dumb http". Note that this does _not_ include `https`; if you want to configure both, you must do so individually. - any external helpers are named by their protocol (e.g., use `hg` to allow the `git-remote-hg` helper) -- protocol.version:: Experimental. If set, clients will attempt to communicate with a server using the specified protocol version. If unset, no attempt will be made by the client to communicate using a particular protocol version, this results in protocol version 0 being used. Supported versions: + -- * `0` - the original wire protocol. * `1` - the original wire protocol with the addition of a version string in the initial response from the server. -- pull.ff:: By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded. When set to `false`, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the `--no-ff` option from the command line). When set to `only`, only such fast-forward merges are allowed (equivalent to giving the `--ff-only` option from the command line). This setting overrides `merge.ff` when pulling. pull.rebase:: When true, rebase branches on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "branch..rebase" for setting this on a per-branch basis. + When `merges`, pass the `--rebase-merges` option to 'git rebase' so that the local merge commits are included in the rebase (see linkgit:git-rebase[1] for details). + When preserve, also pass `--preserve-merges` along to 'git rebase' so that locally committed merge commits will not be flattened by running 'git pull'. + When the value is `interactive`, the rebase is run in interactive mode. + *NOTE*: this is a possibly dangerous operation; do *not* use it unless you understand the implications (see linkgit:git-rebase[1] for details). pull.octopus:: The default merge strategy to use when pulling multiple branches at once. pull.twohead:: The default merge strategy to use when pulling a single branch. push.default:: Defines the action `git push` should take if no refspec is explicitly given. Different values are well-suited for specific workflows; for instance, in a purely central workflow (i.e. the fetch source is equal to the push destination), `upstream` is probably what you want. Possible values are: + -- * `nothing` - do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit. * `current` - push the current branch to update a branch with the same name on the receiving end. Works in both central and non-central workflows. * `upstream` - push the current branch back to the branch whose changes are usually integrated into the current branch (which is called `@{upstream}`). This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow). * `tracking` - This is a deprecated synonym for `upstream`. * `simple` - in centralized workflow, work like `upstream` with an added safety to refuse to push if the upstream branch's name is different from the local one. + When pushing to a remote that is different from the remote you normally pull from, work as `current`. This is the safest option and is suited for beginners. + This mode has become the default in Git 2.0. * `matching` - push all branches having the same name on both ends. This makes the repository you are pushing to remember the set of branches that will be pushed out (e.g. if you always push 'maint' and 'master' there and no other branches, the repository you push to will have these two branches, and your local 'maint' and 'master' will be pushed there). + To use this mode effectively, you have to make sure _all_ the branches you would push out are ready to be pushed out before running 'git push', as the whole point of this mode is to allow you to push all of the branches in one go. If you usually finish work on only one branch and push out the result, while other branches are unfinished, this mode is not for you. Also this mode is not suitable for pushing into a shared central repository, as other people may add new branches there, or update the tip of existing branches outside your control. + This used to be the default, but not since Git 2.0 (`simple` is the new default). -- push.followTags:: If set to true enable `--follow-tags` option by default. You may override this configuration at time of push by specifying `--no-follow-tags`. push.gpgSign:: May be set to a boolean value, or the string 'if-asked'. A true value causes all pushes to be GPG signed, as if `--signed` is passed to linkgit:git-push[1]. The string 'if-asked' causes pushes to be signed if the server supports it, as if `--signed=if-asked` is passed to 'git push'. A false value may override a value from a lower-priority config file. An explicit command-line flag always overrides this config option. push.pushOption:: When no `--push-option=
