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


       git show-ref [-q|--quiet] [--verify] [--head] [-d|--dereference]
                    [-s|--hash[=<n>]] [--abbrev[=<n>]] [--tags]
                    [--heads] [--] [<pattern>...]
       git show-ref --exclude-existing[=<pattern>]


       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.

       Use of this utility is encouraged in favor of directly accessing files
       under the .git directory.


           Show the HEAD reference, even if it would normally be filtered out.

       --tags, --heads
           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 SHA-1 hash, not the reference name. When combined
           with --dereference the dereferenced tag will still be shown after
           the SHA-1.

           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.

           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. When combined with --verify
           this can be used to silently check if a reference exists.

           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.

           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


       The output is in the format: <SHA-1 ID> <space> <reference name>.

           $ 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 format is: <SHA-1

           $ git show-ref --heads --hash


       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 exists.

       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

       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.
