GIT-SHOW-REF(1)			  Git Manual		       GIT-SHOW-REF(1)

NAME
       git-show-ref - List references in a local repository

SYNOPSIS
       git show-ref [-q|--quiet] [--verify] [--head] [-d|--dereference]
		    [-s|--hash[=<n>]] [--abbrev[=<n>]] [--tags]
		    [--heads] [--] [<pattern>...]
       git show-ref --exclude-existing[=<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.

       By default, shows the tags, heads, and remote refs.

       The --exclude-existing form is a	filter that does the inverse. It reads
       refs from stdin,	one ref	per line, and shows those that don't exist in
       the local repository.

       Use of this utility is encouraged in favor of directly accessing	files
       under the .git directory.

OPTIONS
       --head
	   Show	the HEAD reference, even if it would normally be filtered out.

       --heads,	--tags
	   Limit to "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[=<n>]
	   Only	show the SHA-1 hash, not the reference name. When combined
	   with	--dereference the dereferenced tag will	still be shown after
	   the SHA-1.

       --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[=<n>]
	   Abbreviate the object name. When using --hash, you do not have to
	   say --hash --abbrev;	--hash=n 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.

       --exclude-existing[=<pattern>]
	   Make	git show-ref act as a filter that reads	refs from stdin	of the
	   form	"^(?:<anything>\s)?<refname>(?:\^{})?$"	and performs the
	   following actions on	each: (1) strip	"^{}" at the end of line if
	   any;	(2) ignore if pattern is provided and does not head-match
	   refname; (3)	warn if	refname	is not a well-formed refname and skip;
	   (4) ignore if refname is a ref that exists in the local repository;
	   (5) otherwise output	the line.

       <pattern>...
	   Show	references matching one	or more	patterns. Patterns are matched
	   from	the end	of the full name, and only complete parts are matched,
	   e.g.	 master	matches	refs/heads/master, refs/remotes/origin/master,
	   refs/tags/jedi/master but not refs/heads/mymaster or
	   refs/remotes/master/jedi.

OUTPUT
       The output is in	the format: _SHA-1 ID_ _space_ _reference name_.

	   $ git show-ref --head --dereference
	   832e76a9899f560a90ffd62ae2ce83bbeff58f54 HEAD
	   832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/master
	   832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/origin
	   3521017556c5de4159da4615a39fa4d5d2c279b5 refs/tags/v0.99.9c
	   6ddc0964034342519a87fe013781abf31c6db6ad refs/tags/v0.99.9c^{}
	   055e4ae3ae6eb344cbabf2a5256a49ea66040131 refs/tags/v1.0rc4
	   423325a2d24638ddcc82ce47be5e40be550f4507 refs/tags/v1.0rc4^{}
	   ...

       When using --hash (and not --dereference) the output format is: _SHA-1
       ID_

	   $ git show-ref --heads --hash
	   2e3ba0114a1f52b47df29743d6915d056be13278
	   185008ae97960c8d551adcd9e23565194651b5d1
	   03adf42c988195b50e1a1935ba5fcbc39b2b029b
	   ...

EXAMPLES
       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, git show-ref	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.
