6 git-show-ref - List references in a local repository
11 'git-show-ref' [-q|--quiet] [--verify] [-h|--head] [-d|--dereference]
12 [--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. They will be shown with "^{}"
45 Enable stricter reference checking by requiring an exact ref path.
46 Aside from returning an error code of 1, it will also print an error
47 message if '--quiet' was not specified.
51 Do not print any results to stdout. When combined with '--verify' this
52 can be used to silently check if a reference exists.
56 Show references matching one or more patterns.
61 The output is in the format: '<SHA-1 ID>' '<space>' '<reference name>'.

64 $ git show-ref --head --dereference
65 832e76a9899f560a90ffd62ae2ce83bbeff58f54 HEAD
66 832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/master
67 832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/origin
68 3521017556c5de4159da4615a39fa4d5d2c279b5 refs/tags/v0.99.9c
69 6ddc0964034342519a87fe013781abf31c6db6ad refs/tags/v0.99.9c^{}
70 055e4ae3ae6eb344cbabf2a5256a49ea66040131 refs/tags/v1.0rc4

73 -----------------------------------------------------------------------------
78 To show all references called "master", whether tags or heads or anything
79 else, and regardless of how deep in the reference naming hierarchy they are,
82 -----------------------------------------------------------------------------
84 -----------------------------------------------------------------------------
86 This will show "refs/heads/master" but also "refs/remote/other-repo/master",
87 if such references exists.
89 When using the '--verify' flag, the command requires an exact path:
91 -----------------------------------------------------------------------------
92 git show-ref --verify refs/heads/master
93 -----------------------------------------------------------------------------
95 will only match the exact branch called "master".
97 If nothing matches, gitlink:git-show-ref[1] will return an error code of 1,
98 and in the case of verification, it will show an error message.
100 For scripting, you can ask it to be quiet with the "--quiet" flag, which
101 allows you to do things like
103 -----------------------------------------------------------------------------
104 git-show-ref --quiet --verify -- "refs/heads/$headname" ||
105 echo "$headname is not a valid branch"
106 -----------------------------------------------------------------------------
108 to check whether a particular branch exists or not (notice how we don't
109 actually want to show any results, and we want to use the full refname for it
110 in order to not trigger the problem with ambiguous partial matches).
112 To show only tags, or only proper branch heads, use "--tags" and/or "--heads"
113 respectively (using both means that it shows tags and heads, but not other
114 random references under the refs/ subdirectory).
116 To do automatic tag object dereferencing, use the "-d" or "--dereference"
119 -----------------------------------------------------------------------------
120 git show-ref --tags --dereference
121 -----------------------------------------------------------------------------
123 to get a listing of all tags together with what they dereference.
