.SH "DESCRIPTION"
.sp
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\&.
.sp
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 \fIHEAD\fR (i\&.e\&. the tip of the current branch)\&.
.sp
The command\(cqs second form creates a new branch head named <branchname> which points to the current \fIHEAD\fR, or <start\-point> if given\&.
.sp
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\&.
.sp
When a local branch is started off a remote\-tracking branch, git sets up the branch so that \fIgit pull\fR will appropriately merge from the remote\-tracking 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, and changed later using git branch \-\-set\-upstream\&.
.sp
With a \fI\-m\fR or \fI\-M\fR 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\&.
.sp
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\&.
.sp
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 \fIgit fetch\fR was configured not to fetch them again\&. See also the \fIprune\fR subcommand of \fBgit-remote\fR(1) for a way to clean up all obsolete remote\-tracking branches\&.
.SH "OPTIONS"
.PP
\-d
.RS 4
Delete a branch\&. The branch must be fully merged in its upstream branch, or in
HEAD
if no upstream was set with
\-\-track
or
\-\-set\-upstream\&.
.RE
.PP
\-D
.RS 4
Delete a branch irrespective of its merged status\&.
.RE
.PP
\-l
.RS 4
Create the branch\(cqs reflog\&. This activates recording of all changes made to the branch ref, enabling use of date based sha1 expressions such as "<branchname>@{yesterday}"\&. Note that in non\-bare repositories, reflogs are usually enabled by default by the
core\&.logallrefupdates
config option\&.
.RE
.PP
\-f, \-\-force
.RS 4
Reset <branchname> to <startpoint> if <branchname> exists already\&. Without
\-f
\fIgit branch\fR
refuses to change an existing branch\&.
.RE
.PP
\-m
.RS 4
Move/rename a branch and the corresponding reflog\&.
.RE
.PP
\-M
.RS 4
Move/rename a branch even if the new branch name already exists\&.
.RE
.PP
\-\-color[=<when>]
.RS 4
Color branches to highlight current, local, and remote\-tracking branches\&. The value must be always (the default), never, or auto\&.
.RE
.PP
\-\-no\-color
.RS 4
Turn off branch colors, even when the configuration file gives the default to color output\&. Same as
\-\-color=never\&.
.RE
.PP
\-r
.RS 4
List or delete (if used with \-d) the remote\-tracking branches\&.
.RE
.PP
\-a
.RS 4
List both remote\-tracking branches and local branches\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Show sha1 and commit subject line for each head, along with relationship to upstream branch (if any)\&. If given twice, print the name of the upstream branch, as well\&.
.RE
.PP
\-\-abbrev=<length>
.RS 4
Alter the sha1\(cqs minimum display length in the output listing\&. The default value is 7\&.
.RE
.PP
\-\-no\-abbrev
.RS 4
Display the full sha1s in the output listing rather than abbreviating them\&.
.RE
.PP
\-t, \-\-track
.RS 4
When creating a new branch, set up configuration to mark the start\-point branch as "upstream" from the new branch\&. This configuration will tell git to show the relationship between the two branches in
git status
and
git branch \-v\&. Furthermore, it directs
git pull
without arguments to pull from the upstream when the new branch is checked out\&.
.sp
This behavior is the default when the start point is a remote\-tracking branch\&. Set the branch\&.autosetupmerge configuration variable to
false
if you want
git checkout
and
git branch
to always behave as if
\fI\-\-no\-track\fR
were given\&. Set it to
always
if you want this behavior when the start\-point is either a local or remote\-tracking branch\&.
.RE
.PP
\-\-no\-track
.RS 4
Do not set up "upstream" configuration, even if the branch\&.autosetupmerge configuration variable is true\&.
.RE
.PP
\-\-set\-upstream
.RS 4
If specified branch does not exist yet or if
\fI\-\-force\fR
has been given, acts exactly like
\fI\-\-track\fR\&. Otherwise sets up configuration like
\fI\-\-track\fR
would when creating the branch, except that where branch points to is not changed\&.
.RE
.PP
\-\-contains <commit>
.RS 4
Only list branches which contain the specified commit\&.
.RE
.PP
\-\-merged [<commit>]
.RS 4
Only list branches whose tips are reachable from the specified commit (HEAD if not specified)\&.
.RE
.PP
\-\-no\-merged [<commit>]
.RS 4
Only list branches whose tips are not reachable from the specified commit (HEAD if not specified)\&.
.RE
.PP
<branchname>
.RS 4
The name of the branch to create or delete\&. The new branch name must pass all checks defined by
\fBgit-check-ref-format\fR(1)\&. Some of these checks may restrict the characters allowed in a branch name\&.
.RE
.PP
<start\-point>
.RS 4
The new branch head will point to this commit\&. It may be given as a branch name, a commit\-id, or a tag\&. If this option is omitted, the current HEAD will be used instead\&.
.RE
.PP
<oldbranch>
.RS 4
The name of an existing branch to rename\&.
.RE
.PP
<newbranch>
.RS 4
The new name for an existing branch\&. The same restrictions as for <branchname> apply\&.

.RE
.SH "NOTES"
.sp
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\&.
.sp
The options \-\-contains, \-\-merged and \-\-no\-merged serve three related but different purposes:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

\-\-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>\&.
.RE

.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\-\-merged
is used to find all branches which can be safely deleted, since those branches are fully contained by HEAD\&.
