31 git-show-ref \- List references in a local repository
35 \fIgit show\-ref\fR [\-q|\-\-quiet] [\-\-verify] [\-\-head] [\-d|\-\-dereference]
36 [\-s|\-\-hash[=<n>]] [\-\-abbrev[=<n>]] [\-\-tags]
37 [\-\-heads] [\-\-] [<pattern>\&...]
38 \fIgit show\-ref\fR \-\-exclude\-existing[=<pattern>]
43 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\&.
45 By default, shows the tags, heads, and remote refs\&.
47 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\(cqt exist in the local repository\&.
49 Use of this utility is encouraged in favor of directly accessing files under the \fB\&.git\fR directory\&.
54 Show the HEAD reference, even if it would normally be filtered out\&.
59 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\&.
64 Dereference tags into object IDs as well\&. They will be shown with "^{}" appended\&.
69 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\&.
74 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
81 Abbreviate the object name\&. When using
82 \fB\-\-hash\fR, you do not have to say
83 \fB\-\-hash \-\-abbrev\fR;
90 Do not print any results to stdout\&. When combined with
92 this can be used to silently check if a reference exists\&.
95 \-\-exclude\-existing[=<pattern>]
99 act as a filter that reads refs from stdin of the form "\fB^(?:<anything>\es)?<refname>(?:\e^{})?$\fR" 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\&.
104 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\&.
107 \fIrefs/heads/master\fR,
108 \fIrefs/remotes/origin/master\fR,
109 \fIrefs/tags/jedi/master\fR
111 \fIrefs/heads/mymaster\fR
113 \fIrefs/remotes/master/jedi\fR\&.
117 The output is in the format: \fI<SHA\-1 ID>\fR \fI<space>\fR \fI<reference name>\fR\&.
123 $ git show\-ref \-\-head \-\-dereference
124 832e76a9899f560a90ffd62ae2ce83bbeff58f54 HEAD

126 832e76a9899f560a90ffd62ae2ce83bbeff58f54 refs/heads/origin

130 423325a2d24638ddcc82ce47be5e40be550f4507 refs/tags/v1\&.0rc4^{}
138 When using \-\-hash (and not \-\-dereference) the output format is: \fI<SHA\-1 ID>\fR
144 $ git show\-ref \-\-heads \-\-hash

156 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:
169 This will show "refs/heads/master" but also "refs/remote/other\-repo/master", if such references exists\&.
171 When using the \fB\-\-verify\fR flag, the command requires an exact path:
177 git show\-ref \-\-verify refs/heads/master
184 will only match the exact branch called "master"\&.
186 If nothing matches, \fIgit show\-ref\fR will return an error code of 1, and in the case of verification, it will show an error message\&.
188 For scripting, you can ask it to be quiet with the "\-\-quiet" flag, which allows you to do things like
194 git show\-ref \-\-quiet \-\-verify \-\- "refs/heads/$headname" ||
195 echo "$headname is not a valid branch"
202 to check whether a particular branch exists or not (notice how we don\(cqt 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)\&.
204 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)\&.
206 To do automatic tag object dereferencing, use the "\-d" or "\-\-dereference" flag, so you can do
212 git show\-ref \-\-tags \-\-dereference
219 to get a listing of all tags together with what they dereference\&.
