GIT-SHOW-REF(1)                   Git Manual                   GIT-SHOW-REF(1)
NAME
       git-show-ref - List references in a local repository
SYNOPSIS
       git show-ref [--head] [-d | --dereference]
                    [-s | --hash[=<n>]] [--abbrev[=<n>]] [--tags]
                    [--heads] [--] [<pattern>...]
       git show-ref --verify [-q | --quiet] [-d | --dereference]
                    [-s | --hash[=<n>]] [--abbrev[=<n>]]
                    [--] [<ref>...]
       git show-ref --exclude-existing[=<pattern>]
       git show-ref --exists <ref>
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.
       The --exists form can be used to check for the existence of a single
       references. This form does not verify whether the reference resolves to
       an actual object.
       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 OID, not the reference name. When combined with
           --dereference, the dereferenced tag will still be shown after the
           OID.
       --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.
       --exists
           Check whether the given reference exists. Returns an exit code of 0
           if it does, 2 if it is missing, and 1 in case looking up the
           reference failed with an error other than the reference being
           missing.
       --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. Can be used with --verify 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:
           <oid> SP <ref> LF
       For example,
           $ 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 is in the format:
           <oid> LF
       For example,
           $ 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 exist.
       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.
