git-branch(1)
=============
NAME
----
git-branch - List, create, or delete branches
SYNOPSIS
--------
[verse]
'git-branch' [--color | --no-color] [-r | -a]
[-v [--abbrev=<length> | --no-abbrev]]
'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 given a list of existing branches
will be shown, the current branch will be highlighted with an asterisk.
Option `-r` causes the remote-tracking branches to be listed,
and option `-a` shows both.
In its 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.
When a local branch is started off a remote branch, git can setup the
branch so that gitlink:git-pull[1] will appropriately merge from that
remote branch. If this behavior is desired, it is possible to make it
the default using the global `branch.autosetupmerge` configuration
flag. Otherwise, it can be chosen per-branch 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.
OPTIONS
-------
-d::
Delete a branch. The branch must be fully merged.
-D::
Delete a branch irrespective of its index 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::
Force the creation of a new branch even if it means deleting
a branch that already exists with the same name.
-m::
Move/rename a branch and the corresponding reflog.
-M::
Move/rename a branch even if the new branchname 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::
Show sha1 and commit subject line for each head.
--abbrev=<length>::
Alter minimum display length for sha1 in output listing,
default value is 7.
--no-abbrev::
Display the full sha1s in output listing rather than abbreviating them.
<branchname>::
The name of the branch to create or delete.
The new branch name must pass all checks defined by
gitlink: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> applies.
Examples
--------
Start development off of 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 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 remote-tracking branches "todo", "html", "man"
<2> Delete "test" branch even if the "master" branch does not have all
commits from test branch.
Notes
-----
If you are creating a branch that you want to immediately checkout, it's
easier to use the git checkout command with its `-b` option to create
a branch and check it out with a single command.
