git for CVS users
=================
-So you're a CVS user. That's OK, it's a treatable condition. The job of
-this document is to put you on the road to recovery, by helping you
-convert an existing cvs repository to git, and by showing you how to use a
-git repository in a cvs-like fashion.
+Git differs from CVS in that every working tree contains a repository with
+a full copy of the project history, and no repository is inherently more
+important than any other. However, you can emulate the CVS model by
+designating a single shared repository which people can synchronize with;
+this document explains how to do that.
Some basic familiarity with git is required. This
link:tutorial.html[tutorial introduction to git] should be sufficient.

- * Commits are atomic and project-wide, not per-file as in CVS.
-
- * Offline work is supported: you can make multiple commits locally,
- then submit them when you're ready.
-
- * Branching is fast and easy.
-
- * Every working tree contains a repository with a full copy of the
- project history, and no repository is inherently more important than
- any other. However, you can emulate the CVS model by designating a
- single shared repository which people can synchronize with; see below
- for details.
-
-Importing a CVS archive
------------------------
-
-First, install version 2.1 or higher of cvsps from
-link:http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
-sure it is in your path. The magic command line is then
-
--------------------------------------------
-$ git cvsimport -v -d <cvsroot> -C <destination> <module>
--------------------------------------------
-
-This puts a git archive of the named CVS module in the directory
-<destination>, which will be created if necessary. The -v option makes
-the conversion script very chatty.
-
-The import checks out from CVS every revision of every file. Reportedly
-cvsimport can average some twenty revisions per second, so for a
-medium-sized project this should not take more than a couple of minutes.
-Larger projects or remote repositories may take longer.
-
-The main trunk is stored in the git branch named `origin`, and additional
-CVS branches are stored in git branches with the same names. The most
-recent version of the main trunk is also left checked out on the `master`
-branch, so you can start adding your own changes right away.
-
-The import is incremental, so if you call it again next month it will
-fetch any CVS updates that have been made in the meantime. For this to
-work, you must not modify the imported branches; instead, create new
-branches for your own changes, and merge in the imported branches as
-necessary.
-
-Development Models
-------------------
-
-CVS users are accustomed to giving a group of developers commit access to
-a common repository. In the next section we'll explain how to do this
-with git. However, the distributed nature of git allows other development
-models, and you may want to first consider whether one of them might be a
-better fit for your project.
-
-For example, you can choose a single person to maintain the project's
-primary public repository. Other developers then clone this repository
-and each work in their own clone. When they have a series of changes that
-they're happy with, they ask the maintainer to pull from the branch
-containing the changes. The maintainer reviews their changes and pulls
-them into the primary repository, which other developers pull from as
-necessary to stay coordinated. The Linux kernel and other projects use
-variants of this model.
-
-With a small group, developers may just pull changes from each other's
-repositories without the need for a central maintainer.
-
-Emulating the CVS Development Model
------------------------------------
-
-Start with an ordinary git working directory containing the project, and
-remove the checked-out files, keeping just the bare .git directory:
-
-------------------------------------------------
-$ mv project/.git /pub/repo.git
-$ rm -r project/
-------------------------------------------------
-
-Next, give every team member read/write access to this repository. One
-easy way to do this is to give all the team members ssh access to the
-machine where the repository is hosted. If you don't want to give them a
-full shell on the machine, there is a restricted shell which only allows
-users to do git pushes and pulls; see gitlink:git-shell[1].
-
-Put all the committers in the same group, and make the repository
-writable by that group:
-
-------------------------------------------------
-$ chgrp -R $group repo.git
-$ find repo.git -mindepth 1 -type d |xargs chmod ug+rwx,g+s
-$ GIT_DIR=repo.git git repo-config core.sharedrepository true
-------------------------------------------------

-Make sure committers have a umask of at most 027, so that the directories
-they create are writable and searchable by other group members.

+Setting Up a Shared Repository
+------------------------------
+
+We assume you have already created a git repository for your project,
+possibly created from scratch or from a tarball (see the
+link:tutorial.html[tutorial]), or imported from an already existing CVS
+repository (see the next section).
+
+Assume your existing repo is at /home/alice/myproject. Create a new "bare"
+repository (a repository without a working tree) and fetch your project into
+it:
+
+------------------------------------------------
+$ mkdir /pub/my-repo.git
+$ cd /pub/my-repo.git
+$ git --bare init-db --shared
+$ git --bare fetch /home/alice/myproject master:master
+------------------------------------------------
+

+
+First, install version 2.1 or higher of cvsps from

-So, something has gone wrong, and you don't know whom to blame, and
-you're an ex-CVS user and used to do "cvs annotate" to see who caused
-the breakage. You're looking for the "git annotate", and it's just
-claiming not to find such a script. You're annoyed.
-
-Yes, that's right. Core git doesn't do "annotate", although it's
-technically possible, and there are at least two specialized scripts out
-there that can be used to get equivalent information (see the git
-mailing list archives for details).
-
-git has a couple of alternatives, though, that you may find sufficient
-or even superior depending on your use. One is called "git-whatchanged"
-(for obvious reasons) and the other one is called "pickaxe" ("a tool for
-the software archaeologist").
-
-The "git-whatchanged" script is a truly trivial script that can give you
-a good overview of what has changed in a file or a directory (or an
-arbitrary list of files or directories). The "pickaxe" support is an
-additional layer that can be used to further specify exactly what you're
-looking for, if you already know the specific area that changed.
-
-Let's step back a bit and think about the reason why you would
-want to do "cvs annotate a-file.c" to begin with.
-
-You would use "cvs annotate" on a file when you have trouble
-with a function (or even a single "if" statement in a function)
-that happens to be defined in the file, which does not do what
-you want it to do. And you would want to find out why it was
-written that way, because you are about to modify it to suit
-your needs, and at the same time you do not want to break its
-current callers. For that, you are trying to find out why the
-original author did things that way in the original context.
-
-Many times, it may be enough to see the commit log messages of
-commits that touch the file in question, possibly along with the
-patches themselves, like this:
-
- $ git-whatchanged -p a-file.c
-
-This will show log messages and patches for each commit that
-touches a-file.
-
-This, however, may not be very useful when this file has many
-modifications that are not related to the piece of code you are
-interested in. You would see many log messages and patches that
-do not have anything to do with the piece of code you are
-interested in. As an example, assuming that you have this piece
-of code that you are interested in in the HEAD version:
-
- if (frotz) {
- nitfol();
- }
-
-you would use git-rev-list and git-diff-tree like this:
-
- $ git-rev-list HEAD |
- git-diff-tree --stdin -v -p -S'if (frotz) {
- nitfol();
- }'
-
-We have already talked about the "\--stdin" form of git-diff-tree
-command that reads the list of commits and compares each commit
-with its parents (otherwise you should go back and read the tutorial).
-The git-whatchanged command internally runs
-the equivalent of the above command, and can be used like this:
-
- $ git-whatchanged -p -S'if (frotz) {
- nitfol();
- }'
-
-When the -S option is used, git-diff-tree command outputs
-differences between two commits only if one tree has the
-specified string in a file and the corresponding file in the
-other tree does not. The above example looks for a commit that
-has the "if" statement in it in a file, but its parent commit
-does not have it in the same shape in the corresponding file (or
-the other way around, where the parent has it and the commit
-does not), and the differences between them are shown, along
-with the commit message (thanks to the -v flag). It does not
-show anything for commits that do not touch this "if" statement.
-
-Also, in the original context, the same statement might have
-appeared at first in a different file and later the file was
-renamed to "a-file.c". CVS annotate would not help you to go
-back across such a rename, but git would still help you in such
-a situation. For that, you can give the -C flag to
-git-diff-tree, like this:
-
- $ git-whatchanged -p -C -S'if (frotz) {
- nitfol();
- }'
-
-When the -C flag is used, file renames and copies are followed.
-So if the "if" statement in question happens to be in "a-file.c"
-in the current HEAD commit, even if the file was originally
-called "o-file.c" and then renamed in an earlier commit, or if
-the file was created by copying an existing "o-file.c" in an
-earlier commit, you will not lose track. If the "if" statement
-did not change across such a rename or copy, then the commit that
-does rename or copy would not show in the output, and if the
-"if" statement was modified while the file was still called
-"o-file.c", it would find the commit that changed the statement
-when it was in "o-file.c".
-
-NOTE: The current version of "git-diff-tree -C" is not eager
- enough to find copies, and it will miss the fact that a-file.c
- was created by copying o-file.c unless o-file.c was somehow
- changed in the same commit.
-
-You can use the --pickaxe-all flag in addition to the -S flag.
-This causes the differences from all the files contained in
-those two commits, not just the differences between the files
-that contain this changed "if" statement:
-
- $ git-whatchanged -p -C -S'if (frotz) {
- nitfol();
- }' --pickaxe-all
-
-NOTE: This option is called "--pickaxe-all" because -S
- option is internally called "pickaxe", a tool for software
- archaeologists.

+git-add - Add file contents to the changeset to be committed next
SYNOPSIS
--------
-'git-add' [-n] [-v] [--] <file>...
+'git-add' [-n] [-v] [-f] [--interactive] [--] <file>...
DESCRIPTION
-----------
-A simple wrapper for git-update-index to add files to the index,
-for people used to do "cvs add".
+All the changed file contents to be committed together in a single set
+of changes must be "added" with the 'add' command before using the
+'commit' command. This is not only for adding new files. Even modified
+files must be added to the set of changes about to be committed.
+
+This command can be performed multiple times before a commit. The added
+content corresponds to the state of specified file(s) at the time the
+'add' command is used. This means the 'commit' command will not consider
+subsequent changes to already added content if it is not added again before
+the commit.
+
+The 'git status' command can be used to obtain a summary of what is included
+for the next commit.
+
+This command can be used to add ignored files with `-f` (force)
+option, but they have to be
+explicitly and exactly specified from the command line. File globbing
+and recursive behaviour do not add ignored files.
+
+Please see gitlink:git-commit[1] for alternative ways to add content to a
+commit.
-It only adds non-ignored files, to add ignored files use
-"git update-index --add".

-DISCUSSION
-----------
-
-The list of <file> given to the command is fed to `git-ls-files`
-command to list files that are not registered in the index and
-are not ignored/excluded by `$GIT_DIR/info/exclude` file or
-`.gitignore` file in each directory. This means two things:
-
-. You can put the name of a directory on the command line, and
- the command will add all files in it and its subdirectories;
-
-. Giving the name of a file that is already in index does not
- run `git-update-index` on that path.

+
+Interactive mode
+----------------
+When the command enters the interactive mode, it shows the
+output of the 'status' subcommand, and then goes into ints
+interactive command loop.
+
+The command loop shows the list of subcommands available, and
+gives a prompt "What now> ". In general, when the prompt ends
+with a single '>', you can pick only one of the choices given
+and type return, like this:
+
+------------
+ *** Commands ***
+ 1: status 2: update 3: revert 4: add untracked
+ 5: patch 6: diff 7: quit 8: help
+ What now> 1
+------------
+
+You also could say "s" or "sta" or "status" above as long as the
+choice is unique.
+
+The main command loop has 6 subcommands (plus help and quit).
+
+status::
+
+ This shows the change between HEAD and index (i.e. what will be
+ committed if you say "git commit"), and between index and
+ working tree files (i.e. what you could stage further before
+ "git commit" using "git-add") for each path. A sample output
+ looks like this:
++
+------------
+ staged unstaged path
+ 1: binary nothing foo.png
+ 2: +403/-35 +1/-1 git-add--interactive.perl
+------------
++
+It shows that foo.png has differences from HEAD (but that is
+binary so line count cannot be shown) and there is no
+difference between indexed copy and the working tree
+version (if the working tree version were also different,
+'binary' would have been shown in place of 'nothing'). The
+other file, git-add--interactive.perl, has 403 lines added
+and 35 lines deleted if you commit what is in the index, but
+working tree file has further modifications (one addition and
+one deletion).
+
+update::
+
+ This shows the status information and gives prompt
+ "Update>>". When the prompt ends with double '>>', you can
+ make more than one selection, concatenated with whitespace or
+ comma. Also you can say ranges. E.g. "2-5 7,9" to choose
+ 2,3,4,5,7,9 from the list. You can say '*' to choose
+ everything.
++
+What you chose are then highlighted with '*',
+like this:
++
+------------
+ staged unstaged path
+ 1: binary nothing foo.png
+* 2: +403/-35 +1/-1 git-add--interactive.perl
+------------
++
+To remove selection, prefix the input with `-`
+like this:
++
+------------
+Update>> -2
+------------
++
+After making the selection, answer with an empty line to stage the
+contents of working tree files for selected paths in the index.
+
+revert::
+
+ This has a very similar UI to 'update', and the staged
+ information for selected paths are reverted to that of the
+ HEAD version. Reverting new paths makes them untracked.
+
+add untracked::
+
+ This has a very similar UI to 'update' and
+ 'revert', and lets you add untracked paths to the index.
+
+patch::
+
+ This lets you choose one path out of 'status' like selection.
+ After choosing the path, it presents diff between the index
+ and the working tree file and asks you if you want to stage
+ the change of each hunk. You can say:
+
+ y - add the change from that hunk to index
+ n - do not add the change from that hunk to index
+ a - add the change from that hunk and all the rest to index
+ d - do not the change from that hunk nor any of the rest to index
+ j - do not decide on this hunk now, and view the next
+ undecided hunk
+ J - do not decide on this hunk now, and view the next hunk
+ k - do not decide on this hunk now, and view the previous
+ undecided hunk
+ K - do not decide on this hunk now, and view the previous hunk
++
+After deciding the fate for all hunks, if there is any hunk
+that was chosen, the index is updated with the selected hunks.
+
+diff::
+
+ This lets you review what will be committed (i.e. between
+ HEAD and index).

DESCRIPTION
-----------
-Clones a repository into a newly created directory. All remote

+Clones a repository into a newly created directory, creates
+remote-tracking branches for each branch in the cloned repository
+(visible using `git branch -r`), and creates and checks out a master
+branch equal to the cloned repository's master branch.
- Pull: master:origin
-
-This is to help the typical workflow of working off of the
-remote `master` branch. Every time `git pull` without argument
-is run, the progress on the remote `master` branch is tracked by
-copying it into the local `origin` branch, and merged into the
-branch you are currently working on. Remote branches other than
-`master` are also added there to be tracked.
+After the clone, a plain `git fetch` without arguments will update
+all the remote-tracking branches, and a `git pull` without
+arguments will in addition merge the remote master branch into the
+current branch.
+This default configuration is achieved by creating references to
+the remote branch heads under `$GIT_DIR/refs/remotes/origin` and
+by initializing `remote.origin.url` and `remote.origin.fetch`
+configuration variables.

-----------
-
-`git commit` without _any_ parameter commits the tree structure
-recorded by the current index file. This is a whole-tree commit
-even the command is invoked from a subdirectory.
-
-`git commit --include paths...` is equivalent to
-
- git update-index --remove paths...
- git commit
-
-That is, update the specified paths to the index and then commit
-the whole tree.
-
-`git commit paths...` largely bypasses the index file and
-commits only the changes made to the specified paths. It has
-however several safety valves to prevent confusion.
-
-. It refuses to run during a merge (i.e. when
- `$GIT_DIR/MERGE_HEAD` exists), and reminds trained git users
- that the traditional semantics now needs -i flag.
-
-. It refuses to run if named `paths...` are different in HEAD
- and the index (ditto about reminding). Added paths are OK.
- This is because an earlier `git diff` (not `git diff HEAD`)
- would have shown the differences since the last `git
- update-index paths...` to the user, and an inexperienced user
- may mistakenly think that the changes between the index and
- the HEAD (i.e. earlier changes made before the last `git
- update-index paths...` was done) are not being committed.
-
-. It reads HEAD commit into a temporary index file, updates the
- specified `paths...` and makes a commit. At the same time,
- the real index file is also updated with the same `paths...`.
+EXAMPLES
+--------
+When recording your own work, the contents of modified files in
+your working tree are temporarily stored to a staging area
+called the "index" with gitlink:git-add[1]. Removal
+of a file is staged with gitlink:git-rm[1]. After building the
+state to be committed incrementally with these commands, `git
+commit` (without any pathname parameter) is used to record what
+has been staged so far. This is the most basic form of the
+command. An example:
+
+------------
+$ edit hello.c
+$ git rm goodbye.c
+$ git add hello.c
+$ git commit
+------------
+
+////////////
+We should fix 'git rm' to remove goodbye.c from both index and
+working tree for the above example.
+////////////
+
+Instead of staging files after each individual change, you can
+tell `git commit` to notice the changes to the files whose
+contents are tracked in
+your working tree and do corresponding `git add` and `git rm`
+for you. That is, this example does the same as the earlier
+example if there is no other change in your working tree:
+
+------------
+$ edit hello.c
+$ rm goodbye.c
+$ git commit -a
+------------
+
+The command `git commit -a` first looks at your working tree,
+notices that you have modified hello.c and removed goodbye.c,
+and performs necessary `git add` and `git rm` for you.
+
+After staging changes to many files, you can alter the order the
+changes are recorded in, by giving pathnames to `git commit`.
+When pathnames are given, the command makes a commit that
+only records the changes made to the named paths:
+
+------------
+$ edit hello.c hello.h
+$ git add hello.c hello.h
+$ edit Makefile
+$ git commit Makefile
+------------
+
+This makes a commit that records the modification to `Makefile`.
+The changes staged for `hello.c` and `hello.h` are not included
+in the resulting commit. However, their changes are not lost --
+they are still staged and merely held back. After the above
+sequence, if you do:
+
+------------
+$ git commit
+------------
+
+this second commit would record the changes to `hello.c` and
+`hello.h` as expected.
+
+After a merge (initiated by either gitlink:git-merge[1] or
+gitlink:git-pull[1]) stops because of conflicts, cleanly merged
+paths are already staged to be committed for you, and paths that
+conflicted are left in unmerged state. You would have to first
+check which paths are conflicting with gitlink:git-status[1]
+and after fixing them manually in your working tree, you would
+stage the result as usual with gitlink:git-add[1]:
+
+------------
+$ git status | grep unmerged
+unmerged: hello.c
+$ edit hello.c
+$ git add hello.c
+------------
+
+After resolving conflicts and staging the result, `git ls-files -u`
+would stop mentioning the conflicted path. When you are done,
+run `git commit` to finally record the merge:
+
+------------
+$ git commit
+------------
+
+As with the case to record your own changes, you can use `-a`
+option to save typing. One difference is that during a merge
+resolution, you cannot use `git commit` with pathnames to
+alter the order the changes are committed, because the merge
+should be recorded as a single commit. In fact, the command
+refuses to run when given pathnames (but see `-i` option).

DESCRIPTION
-----------
Show changes between two trees, a tree and the working tree, a
tree and the index file, or the index file and the working tree.
-The combination of what is compared with what is determined by
-the number of trees given to the command.
-* When no <tree-ish> is given, the working tree and the index
- file are compared, using `git-diff-files`.
+'git-diff' [--options] [--] [<path>...]::
-* When one <tree-ish> is given, the working tree and the named
- tree are compared, using `git-diff-index`. The option
- `--cached` can be given to compare the index file and
- the named tree.
+ This form is to view the changes you made relative to
+ the index (staging area for the next commit). In other
+ words, the differences are what you _could_ tell git to
+ further add to the index but you still haven't. You can
+ stage these changes by using gitlink:git-add[1].
+
+'git-diff' [--options] --cached [<commit>] [--] [<path>...]::
+
+ This form is to view the changes you staged for the next
+ commit relative to the named <commit>. Typically you
+ would want comparison with the latest commit, so if you
+ do not give <commit>, it defaults to HEAD.
+
+'git-diff' [--options] <commit> [--] [<path>...]::
+
+ This form is to view the changes you have in your
+ working tree relative to the named <commit>. You can
+ use HEAD to compare it with the latest commit, or a
+ branch name to compare with the tip of a different
+ branch.
+
+'git-diff' [--options] <commit> <commit> [--] [<path>...]::
+
+ This form is to view the changes between two <commit>,
+ for example, tips of two branches.
+
+Just in case if you are doing something exotic, it should be
+noted that all of the <commit> in the above description can be
+any <tree-ish>.

- using `git-diff-tree`.

+NAME
+----
+git-merge-file - three-way file merge
+
+
+SYNOPSIS
+--------
+[verse]
+'git-merge-file' [-L <current-name> [-L <base-name> [-L <other-name>]]]
+ [-p|--stdout] [-q|--quiet] <current-file> <base-file> <other-file>
+
+
+DESCRIPTION
+-----------
+git-file-merge incorporates all changes that lead from the `<base-file>`
+to `<other-file>` into `<current-file>`. The result ordinarily goes into
+`<current-file>`. git-merge-file is useful for combining separate changes
+to an original. Suppose `<base-file>` is the original, and both
+`<current-file>` and `<other-file>` are modifications of `<base-file>`.
+Then git-merge-file combines both changes.
+
+A conflict occurs if both `<current-file>` and `<other-file>` have changes
+in a common segment of lines. If a conflict is found, git-merge-file
+normally outputs a warning and brackets the conflict with <<<<<<< and
+>>>>>>> lines. A typical conflict will look like this:
+
+ <<<<<<< A
+ lines in file A
+ =======
+ lines in file B
+ >>>>>>> B
+
+If there are conflicts, the user should edit the result and delete one of
+the alternatives.
+
+The exit value of this program is negative on error, and the number of
+conflicts otherwise. If the merge was clean, the exit value is 0.
+
+git-merge-file is designed to be a minimal clone of RCS merge, that is, it
+implements all of RCS merge's functionality which is needed by
+gitlink:git[1].
+
+
+OPTIONS
+-------
+
+-L <label>::
+ This option may be given up to three times, and
+ specifies labels to be used in place of the
+ corresponding file names in conflict reports. That is,
+ `git-merge-file -L x -L y -L z a b c` generates output that
+ looks like it came from files x, y and z instead of
+ from files a, b and c.
+
+-p::
+ Send results to standard output instead of overwriting
+ `<current-file>`.
+
+-q::
+ Quiet; do not warn about conflicts.
+
+
+EXAMPLES
+--------
+
+git merge-file README.my README README.upstream::
+
+ combines the changes of README.my and README.upstream since README,
+ tries to merge them and writes the result into README.my.
+
+git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345::
+
+ merges tmp/a123 and tmp/c345 with the base tmp/b234, but uses labels
+ `a` and `c` instead of `tmp/a123` and `tmp/c345`.

SYNOPSIS
--------
-'git-rm' [-f] [-n] [-v] [--] <file>...
+'git-rm' [-f] [-n] [-r] [--cached] [--] <file>...
DESCRIPTION
-----------
-A convenience wrapper for git-update-index --remove. For those coming
-from cvs, git-rm provides an operation similar to "cvs rm" or "cvs
-remove".
+Remove files from the working tree and from the index. The
+files have to be identical to the tip of the branch, and no
+updates to its contents must have been placed in the staging
+area (aka index).
OPTIONS
-------
<file>...::
- Files to remove from the index and optionally, from the
- working tree as well.
+ Files to remove. Fileglobs (e.g. `*.c`) can be given to
+ remove all matching files. Also a leading directory name
+ (e.g. `dir` to add `dir/file1` and `dir/file2`) can be
+ given to remove all files in the directory, recursively,
+ but this requires `-r` option to be given for safety.
-f::
- Remove files from the working tree as well as from the index.
+ Override the up-to-date check.
-n::
Don't actually remove the file(s), just show if they exist in
the index.
--v::
- Be verbose.
+-r::
+ Allow recursive removal when a leading directory name is
+ given.
\--::
This option can be used to separate command-line options from
the list of files, (useful when filenames might be mistaken
for command-line options).
+\--cached::
+ This option can be used to tell the command to remove
+ the paths only from the index, leaving working tree
+ files.
+
DISCUSSION
----------
-The list of <file> given to the command is fed to `git-ls-files`
-command to list files that are registered in the index and
-are not ignored/excluded by `$GIT_DIR/info/exclude` file or
-`.gitignore` file in each directory. This means two things:
-
-. You can put the name of a directory on the command line, and the
- command will remove all files in it and its subdirectories (the
- directories themselves are never removed from the working tree);
-
-. Giving the name of a file that is not in the index does not
- remove that file.
+The list of <file> given to the command can be exact pathnames,
+file glob patterns, or leading directory name. The command
+removes only the paths that is known to git. Giving the name of
+a file that you have not told git about does not remove that file.

+ This can be performed multiple times before a commit. Note that this
+ is not only for adding new files. Even modified files must be
+ added to the set of changes about to be committed. The "git status"
+ command gives you a summary of what is included so far for the
+ next commit. When done you should use the 'git commit' command to
+ make it real.
+
+ Note: don't forget to 'add' a file again if you modified it after the
+ first 'add' and before 'commit'. Otherwise only the previous added
+ state of that file will be committed. This is because git tracks
+ content, so what you're really 'add'ing to the commit is the *content*
+ of the file in the state it is in when you 'add' it.
+
+2) By using 'git commit -a' directly
+
+ This is a quick way to automatically 'add' the content from all files
+ that were modified since the previous commit, and perform the actual
+ commit without having to separately 'add' them beforehand. This will
+ not add content from new files i.e. files that were never added before.
+ Those files still have to be added explicitly before performing a
+ commit.
+
+But here's a twist. If you do 'git commit <file1> <file2> ...' then only
+the changes belonging to those explicitly specified files will be
+committed, entirely bypassing the current "added" changes. Those "added"
+changes will still remain available for a subsequent commit though.
+
+However, for normal usage you only have to remember 'git add' + 'git commit'
+and/or 'git commit -a'.

-r"""subprocess - Subprocesses with accessible I/O streams
-
-This module allows you to spawn processes, connect to their
-input/output/error pipes, and obtain their return codes. This module
-intends to replace several other, older modules and functions, like:
-
-os.system
-os.spawn*
-os.popen*
-popen2.*
-commands.*
-
-Information about how the subprocess module can be used to replace these
-modules and functions can be found below.
-
-
-
-Using the subprocess module
-===========================
-This module defines one class called Popen:
-
-class Popen(args, bufsize=0, executable=None,
- stdin=None, stdout=None, stderr=None,
- preexec_fn=None, close_fds=False, shell=False,
- cwd=None, env=None, universal_newlines=False,
- startupinfo=None, creationflags=0):
-
-
-Arguments are:
-
-args should be a string, or a sequence of program arguments. The
-program to execute is normally the first item in the args sequence or
-string, but can be explicitly set by using the executable argument.
-
-On UNIX, with shell=False (default): In this case, the Popen class
-uses os.execvp() to execute the child program. args should normally
-be a sequence. A string will be treated as a sequence with the string
-as the only item (the program to execute).
-
-On UNIX, with shell=True: If args is a string, it specifies the
-command string to execute through the shell. If args is a sequence,
-the first item specifies the command string, and any additional items
-will be treated as additional shell arguments.
-
-On Windows: the Popen class uses CreateProcess() to execute the child
-program, which operates on strings. If args is a sequence, it will be
-converted to a string using the list2cmdline method. Please note that
-not all MS Windows applications interpret the command line the same
-way: The list2cmdline is designed for applications using the same
-rules as the MS C runtime.
-
-bufsize, if given, has the same meaning as the corresponding argument
-to the built-in open() function: 0 means unbuffered, 1 means line
-buffered, any other positive value means use a buffer of
-(approximately) that size. A negative bufsize means to use the system
-default, which usually means fully buffered. The default value for
-bufsize is 0 (unbuffered).
-
-stdin, stdout and stderr specify the executed programs' standard
-input, standard output and standard error file handles, respectively.
-Valid values are PIPE, an existing file descriptor (a positive
-integer), an existing file object, and None. PIPE indicates that a
-new pipe to the child should be created. With None, no redirection
-will occur; the child's file handles will be inherited from the
-parent. Additionally, stderr can be STDOUT, which indicates that the
-stderr data from the applications should be captured into the same
-file handle as for stdout.
-
-If preexec_fn is set to a callable object, this object will be called
-in the child process just before the child is executed.
-
-If close_fds is true, all file descriptors except 0, 1 and 2 will be
-closed before the child process is executed.
-
-if shell is true, the specified command will be executed through the
-shell.
-
-If cwd is not None, the current directory will be changed to cwd
-before the child is executed.
-
-If env is not None, it defines the environment variables for the new
-process.
-
-If universal_newlines is true, the file objects stdout and stderr are
-opened as a text files, but lines may be terminated by any of '\n',
-the Unix end-of-line convention, '\r', the Macintosh convention or
-'\r\n', the Windows convention. All of these external representations
-are seen as '\n' by the Python program. Note: This feature is only
-available if Python is built with universal newline support (the
-default). Also, the newlines attribute of the file objects stdout,
-stdin and stderr are not updated by the communicate() method.
-
-The startupinfo and creationflags, if given, will be passed to the
-underlying CreateProcess() function. They can specify things such as
-appearance of the main window and priority for the new process.
-(Windows only)
-
-
-This module also defines two shortcut functions:
-
-call(*args, **kwargs):
- Run command with arguments. Wait for command to complete, then
- return the returncode attribute.
-
- The arguments are the same as for the Popen constructor. Example:
-
- retcode = call(["ls", "-l"])
-
-
-Exceptions
-----------
-Exceptions raised in the child process, before the new program has
-started to execute, will be re-raised in the parent. Additionally,
-the exception object will have one extra attribute called
-'child_traceback', which is a string containing traceback information
-from the childs point of view.
-
-The most common exception raised is OSError. This occurs, for
-example, when trying to execute a non-existent file. Applications
-should prepare for OSErrors.
-
-A ValueError will be raised if Popen is called with invalid arguments.
-
-
-Security
---------
-Unlike some other popen functions, this implementation will never call
-/bin/sh implicitly. This means that all characters, including shell
-metacharacters, can safely be passed to child processes.
-
-
-Popen objects
-=============
-Instances of the Popen class have the following methods:
-
-poll()
- Check if child process has terminated. Returns returncode
- attribute.
-
-wait()
- Wait for child process to terminate. Returns returncode attribute.
-
-communicate(input=None)
- Interact with process: Send data to stdin. Read data from stdout
- and stderr, until end-of-file is reached. Wait for process to
- terminate. The optional stdin argument should be a string to be
- sent to the child process, or None, if no data should be sent to
- the child.
-
- communicate() returns a tuple (stdout, stderr).
-
- Note: The data read is buffered in memory, so do not use this
- method if the data size is large or unlimited.
-
-The following attributes are also available:
-
-stdin
- If the stdin argument is PIPE, this attribute is a file object
- that provides input to the child process. Otherwise, it is None.
-
-stdout
- If the stdout argument is PIPE, this attribute is a file object
- that provides output from the child process. Otherwise, it is
- None.
-
-stderr
- If the stderr argument is PIPE, this attribute is file object that
- provides error output from the child process. Otherwise, it is
- None.
-
-pid
- The process ID of the child process.
-
-returncode
- The child return code. A None value indicates that the process
- hasn't terminated yet. A negative value -N indicates that the
- child was terminated by signal N (UNIX only).
-
-
-Replacing older functions with the subprocess module
-====================================================
-In this section, "a ==> b" means that b can be used as a replacement
-for a.
-
-Note: All functions in this section fail (more or less) silently if
-the executed program cannot be found; this module raises an OSError
-exception.
-
-In the following examples, we assume that the subprocess module is
-imported with "from subprocess import *".
-
-
-Replacing /bin/sh shell backquote
----------------------------------
-output=`mycmd myarg`
-==>
-output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0]
-
-
-Replacing shell pipe line
--------------------------
-output=`dmesg | grep hda`
-==>
-p1 = Popen(["dmesg"], stdout=PIPE)
-p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
-output = p2.communicate()[0]
-
-
-Replacing os.system()
----------------------
-sts = os.system("mycmd" + " myarg")
-==>
-p = Popen("mycmd" + " myarg", shell=True)
-sts = os.waitpid(p.pid, 0)
-
-Note:
-
-* Calling the program through the shell is usually not required.
-
-* It's easier to look at the returncode attribute than the
- exitstatus.
-
-A more real-world example would look like this:
-
-try:
- retcode = call("mycmd" + " myarg", shell=True)
- if retcode < 0:
- print >>sys.stderr, "Child was terminated by signal", -retcode
- else:
- print >>sys.stderr, "Child returned", retcode
-except OSError, e:
- print >>sys.stderr, "Execution failed:", e
-
-
-Replacing os.spawn*
--------------------
-P_NOWAIT example:
-
-pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg")
-==>
-pid = Popen(["/bin/mycmd", "myarg"]).pid
-
-
-P_WAIT example:
-
-retcode = os.spawnlp(os.P_WAIT, "/bin/mycmd", "mycmd", "myarg")
-==>
-retcode = call(["/bin/mycmd", "myarg"])
-
-
-Vector example:
-
-os.spawnvp(os.P_NOWAIT, path, args)
-==>
-Popen([path] + args[1:])
-
-
-Environment example:
-
-os.spawnlpe(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg", env)
-==>
-Popen(["/bin/mycmd", "myarg"], env={"PATH": "/usr/bin"})
-
-
-Replacing os.popen*
--------------------
-pipe = os.popen(cmd, mode='r', bufsize)
-==>
-pipe = Popen(cmd, shell=True, bufsize=bufsize, stdout=PIPE).stdout
-
-pipe = os.popen(cmd, mode='w', bufsize)
-==>
-pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin
-
-
-(child_stdin, child_stdout) = os.popen2(cmd, mode, bufsize)
-==>
-p = Popen(cmd, shell=True, bufsize=bufsize,
- stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdin, child_stdout) = (p.stdin, p.stdout)
-
-
-(child_stdin,
- child_stdout,
- child_stderr) = os.popen3(cmd, mode, bufsize)
-==>
-p = Popen(cmd, shell=True, bufsize=bufsize,
- stdin=PIPE, stdout=PIPE, stderr=PIPE, close_fds=True)
-(child_stdin,
- child_stdout,
- child_stderr) = (p.stdin, p.stdout, p.stderr)
-
-
-(child_stdin, child_stdout_and_stderr) = os.popen4(cmd, mode, bufsize)
-==>
-p = Popen(cmd, shell=True, bufsize=bufsize,
- stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True)
-(child_stdin, child_stdout_and_stderr) = (p.stdin, p.stdout)
-
-
-Replacing popen2.*
-------------------
-Note: If the cmd argument to popen2 functions is a string, the command
-is executed through /bin/sh. If it is a list, the command is directly
-executed.
-
-(child_stdout, child_stdin) = popen2.popen2("somestring", bufsize, mode)
-==>
-p = Popen(["somestring"], shell=True, bufsize=bufsize
- stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdout, child_stdin) = (p.stdout, p.stdin)
-
-
-(child_stdout, child_stdin) = popen2.popen2(["mycmd", "myarg"], bufsize, mode)
-==>
-p = Popen(["mycmd", "myarg"], bufsize=bufsize,
- stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdout, child_stdin) = (p.stdout, p.stdin)
-
-The popen2.Popen3 and popen3.Popen4 basically works as subprocess.Popen,
-except that:
-
-* subprocess.Popen raises an exception if the execution fails
-* the capturestderr argument is replaced with the stderr argument.
-* stdin=PIPE and stdout=PIPE must be specified.
-* popen2 closes all filedescriptors by default, but you have to specify
- close_fds=True with subprocess.Popen.
