NAME

6       git-show-ref - List references in a local repository
7

SYNOPSIS

9       git show-ref [--head] [-d | --dereference]
10                    [-s | --hash[=<n>]] [--abbrev[=<n>]] [--tags]
11                    [--heads] [--] [<pattern>...]
12       git show-ref --verify [-q | --quiet] [-d | --dereference]
13                    [-s | --hash[=<n>]] [--abbrev[=<n>]]
14                    [--] [<ref>...]
15       git show-ref --exclude-existing[=<pattern>]
16       git show-ref --exists <ref>
17

DESCRIPTION

19       Displays references available in a local repository along with the
20       associated commit IDs. Results can be filtered using a pattern and tags
21       can be dereferenced into object IDs. Additionally, it can be used to
22       test whether a particular ref exists.
23
24       By default, shows the tags, heads, and remote refs.
25
26       The --exclude-existing form is a filter that does the inverse. It reads
27       refs from stdin, one ref per line, and shows those that don’t exist in
28       the local repository.
29
30       The --exists form can be used to check for the existence of a single
31       references. This form does not verify whether the reference resolves to
32       an actual object.
33
34       Use of this utility is encouraged in favor of directly accessing files
35       under the .git directory.
36

OPTIONS

38       --head
39           Show the HEAD reference, even if it would normally be filtered out.
40
41       --heads, --tags
42           Limit to "refs/heads" and "refs/tags", respectively. These options
43           are not mutually exclusive; when given both, references stored in
44           "refs/heads" and "refs/tags" are displayed.
45
46       -d, --dereference
47           Dereference tags into object IDs as well. They will be shown with
48           ^{} appended.
49
50       -s, --hash[=<n>]
51           Only show the OID, not the reference name. When combined with
52           --dereference, the dereferenced tag will still be shown after the
53           OID.
54
55       --verify
56           Enable stricter reference checking by requiring an exact ref path.
57           Aside from returning an error code of 1, it will also print an
58           error message if --quiet was not specified.
59
60       --exists
61           Check whether the given reference exists. Returns an exit code of 0
62           if it does, 2 if it is missing, and 1 in case looking up the
63           reference failed with an error other than the reference being
64           missing.
65
66       --abbrev[=<n>]
67           Abbreviate the object name. When using --hash, you do not have to
68           say --hash --abbrev; --hash=n would do.
69
70       -q, --quiet
71           Do not print any results to stdout. Can be used with --verify to
72           silently check if a reference exists.
73
74       --exclude-existing[=<pattern>]
75           Make git show-ref act as a filter that reads refs from stdin of the
76           form ^(?:<anything>\s)?<refname>(?:\^{})?$ and performs the
77           following actions on each: (1) strip ^{} at the end of line if any;
78           (2) ignore if pattern is provided and does not head-match refname;
79           (3) warn if refname is not a well-formed refname and skip; (4)
80           ignore if refname is a ref that exists in the local repository; (5)
81           otherwise output the line.
82
83       <pattern>...
84           Show references matching one or more patterns. Patterns are matched
85           from the end of the full name, and only complete parts are matched,
86           e.g.  master matches refs/heads/master, refs/remotes/origin/master,
87           refs/tags/jedi/master but not refs/heads/mymaster or
88           refs/remotes/master/jedi.

OUTPUT

91       The output is in the format:
92
93           <oid> SP <ref> LF
94
95       For example,
96
97           $ git show-ref --head --dereference
98           832e76a9899f560a90ffd62ae2ce83bbeff58f54 HEAD
99           832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/master
100           832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/origin
101           3521017556c5de4159da4615a39fa4d5d2c279b5 refs/tags/v0.99.9c
102           6ddc0964034342519a87fe013781abf31c6db6ad refs/tags/v0.99.9c^{}
103           055e4ae3ae6eb344cbabf2a5256a49ea66040131 refs/tags/v1.0rc4
104           423325a2d24638ddcc82ce47be5e40be550f4507 refs/tags/v1.0rc4^{}
105           ...
106
107       When using --hash (and not --dereference), the output is in the format:
108
109           <oid> LF
110
111       For example,
112
113           $ git show-ref --heads --hash
114           2e3ba0114a1f52b47df29743d6915d056be13278
115           185008ae97960c8d551adcd9e23565194651b5d1
116           03adf42c988195b50e1a1935ba5fcbc39b2b029b
117           ...
118

EXAMPLES

120       To show all references called "master", whether tags or heads or
121       anything else, and regardless of how deep in the reference naming
122       hierarchy they are, use:
123
124                   git show-ref master
125
126       This will show "refs/heads/master" but also
127       "refs/remote/other-repo/master", if such references exist.
128
129       When using the --verify flag, the command requires an exact path:
130
131                   git show-ref --verify refs/heads/master
132
133       will only match the exact branch called "master".
134
135       If nothing matches, git show-ref will return an error code of 1, and in
136       the case of verification, it will show an error message.
137
138       For scripting, you can ask it to be quiet with the --quiet flag, which
139       allows you to do things like
140
141                   git show-ref --quiet --verify -- "refs/heads/$headname" ||
142                           echo "$headname is not a valid branch"
143
144       to check whether a particular branch exists or not (notice how we don’t
145       actually want to show any results, and we want to use the full refname
146       for it in order to not trigger the problem with ambiguous partial
147       matches).
148
149       To show only tags, or only proper branch heads, use --tags and/or
150       --heads respectively (using both means that it shows tags and heads,
151       but not other random references under the refs/ subdirectory).
152
153       To do automatic tag object dereferencing, use the -d or --dereference
154       flag, so you can do
155
156                   git show-ref --tags --dereference
157
158       to get a listing of all tags together with what they dereference.
