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

85 When using --hash (and not --dereference) the output format is: '<SHA-1 ID>'
87 -----------------------------------------------------------------------------
88 $ git show-ref --heads --hash

93 -----------------------------------------------------------------------------
98 To show all references called "master", whether tags or heads or anything
99 else, and regardless of how deep in the reference naming hierarchy they are,
102 -----------------------------------------------------------------------------
104 -----------------------------------------------------------------------------
106 This will show "refs/heads/master" but also "refs/remote/other-repo/master",
107 if such references exists.
109 When using the '--verify' flag, the command requires an exact path:
111 -----------------------------------------------------------------------------
112 git show-ref --verify refs/heads/master
113 -----------------------------------------------------------------------------
115 will only match the exact branch called "master".
117 If nothing matches, gitlink:git-show-ref[1] will return an error code of 1,
118 and in the case of verification, it will show an error message.
120 For scripting, you can ask it to be quiet with the "--quiet" flag, which
121 allows you to do things like
123 -----------------------------------------------------------------------------
124 git-show-ref --quiet --verify -- "refs/heads/$headname" ||
125 echo "$headname is not a valid branch"
126 -----------------------------------------------------------------------------
128 to check whether a particular branch exists or not (notice how we don't
129 actually want to show any results, and we want to use the full refname for it
130 in order to not trigger the problem with ambiguous partial matches).
132 To show only tags, or only proper branch heads, use "--tags" and/or "--heads"
133 respectively (using both means that it shows tags and heads, but not other
134 random references under the refs/ subdirectory).
136 To do automatic tag object dereferencing, use the "-d" or "--dereference"
139 -----------------------------------------------------------------------------
140 git show-ref --tags --dereference
141 -----------------------------------------------------------------------------
143 to get a listing of all tags together with what they dereference.
