NAME

----
|
|
git-show-ref - List references in a local repository
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git show-ref' [-q|--quiet] [--verify] [--head] [-d|--dereference]
|
|
[-s|--hash[=<n>]] [--abbrev[=<n>]] [--tags]
|
|
[--heads] [--] [<pattern>...]
|
|
'git show-ref' --exclude-existing[=<pattern>]
|
|
|
|
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.
|
|
|
|
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 "{caret}{}"
|
|
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 "{caret}{}" 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: '<SHA-1 ID>' '<space>' '<reference name>'.

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.
