+git-for-each-ref(1)
+===================
+
+NAME
+----
+git-for-each-ref - Output information on each ref
+
+SYNOPSIS
+--------
+'git-for-each-ref' [--count=<count>]\* [--shell|--perl|--python] [--sort=<key>]\* [--format=<format>] [<pattern>]
+
+DESCRIPTION
+-----------
+
+Iterate over all refs that match `<pattern>` and show them
+according to the given `<format>`, after sorting them according
+to the given set of `<key>`. If `<max>` is given, stop after
+showing that many refs. The interporated values in `<format>`
+can optionally be quoted as string literals in the specified
+host language allowing their direct evaluation in that language.
+
+OPTIONS
+-------
+<count>::
+ By default the command shows all refs that match
+ `<pattern>`. This option makes it stop after showing
+ that many refs.
+
+<key>::
+ A field name to sort on. Prefix `-` to sort in
+ descending order of the value. When unspecified,
+ `refname` is used. More than one sort keys can be
+ given.
+
+<format>::
+ A string that interpolates `%(fieldname)` from the
+ object pointed at by a ref being shown. If `fieldname`
+ is prefixed with an asterisk (`*`) and the ref points
+ at a tag object, the value for the field in the object
+ tag refers is used. When unspecified, defaults to
+ `%(objectname) SPC %(objecttype) TAB %(refname)`.
+ It also interpolates `%%` to `%`, and `%xx` where `xx`
+ are hex digits interpolates to character with hex code
+ `xx`; for example `%00` interpolates to `\0` (NUL),
+ `%09` to `\t` (TAB) and `%0a` to `\n` (LF).
+
+<pattern>::
+ If given, the name of the ref is matched against this
+ using fnmatch(3). Refs that do not match the pattern
+ are not shown.
+
+--shell, --perl, --python::
+ If given, strings that substitute `%(fieldname)`
+ placeholders are quoted as string literals suitable for
+ the specified host language. This is meant to produce
+ a scriptlet that can directly be `eval`ed.
+
+
+FIELD NAMES
+-----------
+
+Various values from structured fields in referenced objects can
+be used to interpolate into the resulting output, or as sort
+keys.
+
+For all objects, the following names can be used:
+
+refname::
+ The name of the ref (the part after $GIT_DIR/refs/).
+
+objecttype::
+ The type of the object (`blob`, `tree`, `commit`, `tag`).
+
+objectsize::
+ The size of the object (the same as `git-cat-file -s` reports).
+
+objectname::
+ The object name (aka SHA-1).
+
+In addition to the above, for commit and tag objects, the header
+field names (`tree`, `parent`, `object`, `type`, and `tag`) can
+be used to specify the value in the header field.
+
+Fields that have name-email-date tuple as its value (`author`,
+`committer`, and `tagger`) can be suffixed with `name`, `email`,
+and `date` to extract the named component.
+
+The first line of the message in a commit and tag object is
+`subject`, the remaining lines are `body`. The whole message
+is `contents`.
+
+For sorting purposes, fields with numeric values sort in numeric
+order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
+All other fields are used to sort in their byte-value order.
+
+In any case, a field name that refers to a field inapplicable to
+the object referred by the ref does not cause an error. It
+returns an empty string instead.
+
+
+EXAMPLES
+--------
+
+An example directly producing formatted text. Show the most recent
+3 tagged commits::
+
+------------
+#!/bin/sh
+
+git-for-each-ref --count=3 --sort='-*authordate' \
+--format='From: %(*authorname) %(*authoremail)
+Subject: %(*subject)
+Date: %(*authordate)
+Ref: %(*refname)
+
+%(*body)
+' 'refs/tags'
+------------
+
+
+A simple example showing the use of shell eval on the output,
+demonstrating the use of --shell. List the prefixes of all heads::
+------------
+#!/bin/sh
+
+git-for-each-ref --shell --format="ref=%(refname)" refs/heads | \
+while read entry
+do
+ eval "$entry"
+ echo `dirname $ref`
+done
+------------
+
+
+A bit more elaborate report on tags, demonstrating that the format
+may be an entire script::
+------------
+#!/bin/sh
+
+fmt='
+ r=%(refname)
+ t=%(*objecttype)
+ T=${r#refs/tags/}
+
+ o=%(*objectname)
+ n=%(*authorname)
+ e=%(*authoremail)
+ s=%(*subject)
+ d=%(*authordate)
+ b=%(*body)
+
+ kind=Tag
+ if test "z$t" = z
+ then
+ # could be a lightweight tag
+ t=%(objecttype)
+ kind="Lightweight tag"
+ o=%(objectname)
+ n=%(authorname)
+ e=%(authoremail)
+ s=%(subject)
+ d=%(authordate)
+ b=%(body)
+ fi
+ echo "$kind $T points at a $t object $o"
+ if test "z$t" = zcommit
+ then
+ echo "The commit was authored by $n $e
+at $d, and titled
+
+ $s
+
+Its message reads as:
+"
+ echo "$b" | sed -e "s/^/ /"
+ echo
+ fi
+'
+
+eval=`git-for-each-ref --shell --format="$fmt" \
+ --sort='*objecttype' \
+ --sort=-taggerdate \
+ refs/tags`
+eval "$eval"

+When configuration variable `repack.UseDeltaBaseOffset` is set

+option to `git-pack-objects`; this typically results in slightly
+smaller packs, but the generated packs are incompatible with

+the variable in a repository that older version of git needs to
+be able to read (this includes repositories from which packs can
+be copied out over http or rsync, and people who obtained packs
+that way can try to use older git with it).

+ [-s|--hash] [--abbrev] [--tags] [--heads] [--] <pattern>...
+
+DESCRIPTION
+-----------
+
+Displays references available in a local repository along with the associated
+commit IDs. Results can be filtered using a pattern and tags can be
+dereferenced into object IDs. Additionally, it can be used to test whether a
+particular ref exists.
+
+Use of this utility is encouraged in favor of directly accessing files under
+in the `.git` directory.
+
+OPTIONS
+-------
+
+-h, --head::
+
+ Show the HEAD reference.
+
+--tags, --heads::
+
+ Limit to only "refs/heads" and "refs/tags", respectively. These
+ options are not mutually exclusive; when given both, references stored
+ in "refs/heads" and "refs/tags" are displayed.
+
+-d, --dereference::
+
+ Dereference tags into object IDs as well. They will be shown with "^{}"
+ appended.
+
+-s, --hash::
+
+ Only show the SHA1 hash, not the reference name. When also using
+ --dereference the dereferenced tag will still be shown after the SHA1.
+
+--verify::
+
+ Enable stricter reference checking by requiring an exact ref path.
+ Aside from returning an error code of 1, it will also print an error
+ message if '--quiet' was not specified.
+
+--abbrev, --abbrev=len::
+
+ Abbreviate the object name. When using `--hash`, you do
+ not have to say `--hash --abbrev`; `--hash=len` would do.
+
+-q, --quiet::
+
+ Do not print any results to stdout. When combined with '--verify' this
+ can be used to silently check if a reference exists.
+
+<pattern>::
+
+ Show references matching one or more patterns.
+
+OUTPUT
+------
+
+The output is in the format: '<SHA-1 ID>' '<space>' '<reference name>'.

+...
+-----------------------------------------------------------------------------
+
+EXAMPLE
+-------
+
+To show all references called "master", whether tags or heads or anything
+else, and regardless of how deep in the reference naming hierarchy they are,
+use:
+
+-----------------------------------------------------------------------------
+ git show-ref master
+-----------------------------------------------------------------------------
+
+This will show "refs/heads/master" but also "refs/remote/other-repo/master",
+if such references exists.
+
+When using the '--verify' flag, the command requires an exact path:
+
+-----------------------------------------------------------------------------
+ git show-ref --verify refs/heads/master
+-----------------------------------------------------------------------------
+
+will only match the exact branch called "master".
+
+If nothing matches, gitlink:git-show-ref[1] will return an error code of 1,
+and in the case of verification, it will show an error message.
+
+For scripting, you can ask it to be quiet with the "--quiet" flag, which
+allows you to do things like
+
+-----------------------------------------------------------------------------
+ git-show-ref --quiet --verify -- "refs/heads/$headname" ||
+ echo "$headname is not a valid branch"
+-----------------------------------------------------------------------------
+
+to check whether a particular branch exists or not (notice how we don't
+actually want to show any results, and we want to use the full refname for it
+in order to not trigger the problem with ambiguous partial matches).
+
+To show only tags, or only proper branch heads, use "--tags" and/or "--heads"
+respectively (using both means that it shows tags and heads, but not other
+random references under the refs/ subdirectory).
+
+To do automatic tag object dereferencing, use the "-d" or "--dereference"
+flag, so you can do
+
+-----------------------------------------------------------------------------
+ git show-ref --tags --dereference
+-----------------------------------------------------------------------------
+
+to get a listing of all tags together with what they dereference.
