git-branch - List, create, or delete branches |

SYNOPSIS |
|
-------- |
|
[verse] |
|
'git branch' [--color | --no-color] [-r | -a] |
|
[-v [--abbrev=<length> | --no-abbrev]] |
|
[(--merged | --no-merged | --contains) [<commit>]] |
|
'git branch' [--track | --no-track] [-l] [-f] <branchname> [<start-point>] |
|
'git branch' (-m | -M) [<oldbranch>] <newbranch> |
|
'git branch' (-d | -D) [-r] <branchname>... |
|
|
|
DESCRIPTION |
|
----------- |
|
|
|
With no arguments, existing branches are listed and the current branch will |
|
be highlighted with an asterisk. Option `-r` causes the remote-tracking |
|
branches to be listed, and option `-a` shows both. |
|
|
|
With `--contains`, shows only the branches that contain the named commit |
|
(in other words, the branches whose tip commits are descendants of the |
|
named commit). With `--merged`, only branches merged into the named |
|
commit (i.e. the branches whose tip commits are reachable from the named |
|
commit) will be listed. With `--no-merged` only branches not merged into |
|
the named commit will be listed. If the <commit> argument is missing it |
|
defaults to 'HEAD' (i.e. the tip of the current branch). |
|
|
|
In the command's second form, a new branch named <branchname> will be created. |
|
It will start out with a head equal to the one given as <start-point>. |
|
If no <start-point> is given, the branch will be created with a head |
|
equal to that of the currently checked out branch. |
|
|
|
Note that this will create the new branch, but it will not switch the |
|
working tree to it; use "git checkout <newbranch>" to switch to the |
|
new branch. |
|
|
|
When a local branch is started off a remote branch, git sets up the |
|
branch so that 'git-pull' will appropriately merge from |
|
the remote branch. This behavior may be changed via the global |
|
`branch.autosetupmerge` configuration flag. That setting can be |
|
overridden by using the `--track` and `--no-track` options. |
|
|
|
With a '-m' or '-M' option, <oldbranch> will be renamed to <newbranch>. |
|
If <oldbranch> had a corresponding reflog, it is renamed to match |
|
<newbranch>, and a reflog entry is created to remember the branch |
|
renaming. If <newbranch> exists, -M must be used to force the rename |
|
to happen. |
|
|
|
With a `-d` or `-D` option, `<branchname>` will be deleted. You may |
|
specify more than one branch for deletion. If the branch currently |
|
has a reflog then the reflog will also be deleted. |
|
|
|
Use -r together with -d to delete remote-tracking branches. Note, that it |
|
only makes sense to delete remote-tracking branches if they no longer exist |
|
in the remote repository or if 'git-fetch' was configured not to fetch |
|
them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a |
|
way to clean up all obsolete remote-tracking branches. |
|
|
|
|
|
OPTIONS |
|
------- |
|
-d:: |
|
Delete a branch. The branch must be fully merged in HEAD. |
|
|
|
-D:: |
|
Delete a branch irrespective of its merged status. |
|
|
|
-l:: |
|
Create the branch's reflog. This activates recording of |
|
all changes made to the branch ref, enabling use of date |
|
based sha1 expressions such as "<branchname>@\{yesterday}". |
|
|
|
-f:: |
|
Reset <branchname> to <startpoint> if <branchname> exists |
|
already. Without `-f` 'git-branch' refuses to change an existing branch. |
|
|
|
-m:: |
|
Move/rename a branch and the corresponding reflog. |
|
|
|
-M:: |
|
Move/rename a branch even if the new branch name already exists. |
|
|
|
--color:: |
|
Color branches to highlight current, local, and remote branches. |
|
|
|
--no-color:: |
|
Turn off branch colors, even when the configuration file gives the |
|
default to color output. |
|
|
|
-r:: |
|
List or delete (if used with -d) the remote-tracking branches. |
|
|
|
-a:: |
|
List both remote-tracking branches and local branches. |
|
|
|
-v:: |
|
--verbose:: |
|
Show sha1 and commit subject line for each head. |
|
|
|
--abbrev=<length>:: |
|
Alter the sha1's minimum display length in the output listing. |
|
The default value is 7. |
|
|
|
--no-abbrev:: |
|
Display the full sha1s in the output listing rather than abbreviating them. |
|
|
|
--track:: |
|
When creating a new branch, set up the configuration so that 'git-pull' |
|
will automatically retrieve data from the start point, which must be |
|
a branch. Use this if you always pull from the same upstream branch |
|
into the new branch, and if you do not want to use "git pull |
|
<repository> <refspec>" explicitly. This behavior is the default |
|
when the start point is a remote branch. Set the |
|
branch.autosetupmerge configuration variable to `false` if you want |
|
'git-checkout' and 'git-branch' to always behave as if '--no-track' were |
|
given. Set it to `always` if you want this behavior when the |
|
start-point is either a local or remote branch. |
|
|
|
--no-track:: |
|
Ignore the branch.autosetupmerge configuration variable. |
|
|
|
--contains <commit>:: |
|
Only list branches which contain the specified commit. |
|
|
|
--merged:: |
|
Only list branches which are fully contained by HEAD. |
|
|
|
--no-merged:: |
|
Do not list branches which are fully contained by HEAD. |
|
|
|
<branchname>:: |
|
The name of the branch to create or delete. |
|
The new branch name must pass all checks defined by |
|
linkgit:git-check-ref-format[1]. Some of these checks |
|
may restrict the characters allowed in a branch name. |
|
|
|
<start-point>:: |
|
The new branch will be created with a HEAD equal to this. It may |
|
be given as a branch name, a commit-id, or a tag. If this option |
|
is omitted, the current branch is assumed. |
|
|
|
<oldbranch>:: |
|
The name of an existing branch to rename. |
|
|
|
<newbranch>:: |
|
The new name for an existing branch. The same restrictions as for |
|
<branchname> apply. |
|
|
|
|
|
Examples |
|
-------- |
|
|
|
Start development from a known tag:: |
|
+ |
|
------------ |
|
$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6 |
|
$ cd my2.6 |
|
$ git branch my2.6.14 v2.6.14 <1> |
|
$ git checkout my2.6.14 |
|
------------ |
|
+ |
|
<1> This step and the next one could be combined into a single step with |
|
"checkout -b my2.6.14 v2.6.14". |
|
|
|
Delete an unneeded branch:: |
|
+ |
|
------------ |
|
$ git clone git://git.kernel.org/.../git.git my.git |
|
$ cd my.git |
|
$ git branch -d -r origin/todo origin/html origin/man <1> |
|
$ git branch -D test <2> |
|
------------ |
|
+ |
|
<1> Delete the remote-tracking branches "todo", "html" and "man". The next |
|
'fetch' or 'pull' will create them again unless you configure them not to. |
|
See linkgit:git-fetch[1]. |
|
<2> Delete the "test" branch even if the "master" branch (or whichever branch |
|
is currently checked out) does not have all commits from the test branch. |
|
|
|
|
|
Notes |
|
----- |
|
|
|
If you are creating a branch that you want to checkout immediately, it is |
|
easier to use the git checkout command with its `-b` option to create |
|
a branch and check it out with a single command. |
|
|
|
The options `--contains`, `--merged` and `--no-merged` serve three related |
|
but different purposes: |
|
|
|
- `--contains <commit>` is used to find all branches which will need |
|
special attention if <commit> were to be rebased or amended, since those |
|
branches contain the specified <commit>. |
|
|
|
- `--merged` is used to find all branches which can be safely deleted, |
|
since those branches are fully contained by HEAD. |
|
|
|
- `--no-merged` is used to find branches which are candidates for merging |
|
into HEAD, since those branches are not fully contained by HEAD. |
