Имя (Name)
git-show-ref - List references in a local repository
Синопсис (Synopsis)
git show-ref [-q|--quiet] [--verify] [--head] [-d|--dereference]
[-s|--hash[=<n>]] [--abbrev[=<n>]] [--tags]
[--heads] [--] [<pattern>...]
git show-ref --exclude-existing[=<pattern>]
Описание (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.
Use of this utility is encouraged in favor of directly accessing
files under the .git directory.
Параметры (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 SHA-1 hash, not the reference name. When
combined with --dereference the dereferenced tag will still
be shown after the SHA-1.
--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.
--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. When combined with
--verify this can be used 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.
Вывод (Output)
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 ID>
$ git show-ref --heads --hash
2e3ba0114a1f52b47df29743d6915d056be13278
185008ae97960c8d551adcd9e23565194651b5d1

Примеры (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 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 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.
