| 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>] < ref-list |
| |
| 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 shows the |
| refs from stdin 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. |
| |
| --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 "{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' nor |
| 'refs/remotes/master/jedi'. |
| |
| 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^{} |

| ... |
| ----------------------------------------------------------------------------- |
| |
| When using --hash (and not --dereference) the output format is: '<SHA-1 ID>' |
| |
| ----------------------------------------------------------------------------- |
| $ git show-ref --heads --hash |

| |
| EXAMPLE |
| ------- |
| |
| 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. |
