  18DESCRIPTION
  19-----------
  20With no arguments given a list of existing branches
  21will be shown, the current branch will be highlighted with an asterisk.
  22Option `-r` causes the remote-tracking branches to be listed,
  23and option `-a` shows both.
  24With `--contains <commit>`, shows only the branches that
  25contains the named commit (in other words, the branches whose
  26tip commits are descendant of the named commit).
  27
  28In its second form, a new branch named <branchname> will be created.
  29It will start out with a head equal to the one given as <start-point>.
  30If no <start-point> is given, the branch will be created with a head
  31equal to that of the currently checked out branch.
  32
  33Note that this will create the new branch, but it will not switch the
  34working tree to it; use "git checkout <newbranch>" to switch to the
  35new branch.
  36
  37When a local branch is started off a remote branch, git sets up the
  38branch so that linkgit:git-pull[1] will appropriately merge from
  39the remote branch. This behavior may be changed via the global
  40`branch.autosetupmerge` configuration flag. That setting can be
  41overridden by using the `--track` and `--no-track` options.
  42
  43With a '-m' or '-M' option, <oldbranch> will be renamed to <newbranch>.
  44If <oldbranch> had a corresponding reflog, it is renamed to match
  45<newbranch>, and a reflog entry is created to remember the branch
  46renaming. If <newbranch> exists, -M must be used to force the rename
  47to happen.
  48
  49With a `-d` or `-D` option, `<branchname>` will be deleted.  You may
  50specify more than one branch for deletion.  If the branch currently
  51has a reflog then the reflog will also be deleted.
  52
  53Use -r together with -d to delete remote-tracking branches. Note, that it
  54only makes sense to delete remote-tracking branches if they no longer exist
  55in remote repository or if linkgit:git-fetch[1] was configured not to fetch
  56them again. See also 'prune' subcommand of linkgit:git-remote[1] for way to
  57clean up all obsolete remote-tracking branches.
  58

  60OPTIONS
  61-------
  62-d::
  63        Delete a branch. The branch must be fully merged in HEAD.
  64
  65-D::
  66        Delete a branch irrespective of its merged status.
  67
  68-l::
  69        Create the branch's reflog.  This activates recording of
  70        all changes made to the branch ref, enabling use of date
  71        based sha1 expressions such as "<branchname>@\{yesterday}".
  72
  73-f::
  74        Force the creation of a new branch even if it means deleting
  75        a branch that already exists with the same name.
  76
  77-m::
  78        Move/rename a branch and the corresponding reflog.
  79
  80-M::
  81        Move/rename a branch even if the new branchname already exists.
  82
  83--color::
  84        Color branches to highlight current, local, and remote branches.
  85
  86--no-color::
  87        Turn off branch colors, even when the configuration file gives the
  88        default to color output.
  89
  90-r::
  91        List or delete (if used with -d) the remote-tracking branches.
  92
  93-a::
  94        List both remote-tracking branches and local branches.
  95
  96-v, --verbose::
  97        Show sha1 and commit subject line for each head.
  98
  99--abbrev=<length>::
 100        Alter minimum display length for sha1 in output listing,
 101        default value is 7.
 102
 103--no-abbrev::
 104        Display the full sha1s in output listing rather than abbreviating them.
 105
 106--track::
 107        When creating a new branch, set up configuration so that git-pull
 108        will automatically retrieve data from the start point, which must be
 109        a branch. Use this if you always pull from the same upstream branch
 110        into the new branch, and if you don't want to use "git pull
 111        <repository> <refspec>" explicitly. This behavior is the default
 112        when the start point is a remote branch. Set the
 113        branch.autosetupmerge configuration variable to `false` if you want
 114        git-checkout and git-branch to always behave as if '--no-track' were
 115        given. Set it to `always` if you want this behavior when the
 116        start-point is either a local or remote branch.
 117
 118--no-track::
 119        Ignore the branch.autosetupmerge configuration variable.
 120
 121<branchname>::
 122        The name of the branch to create or delete.
 123        The new branch name must pass all checks defined by
 124        linkgit:git-check-ref-format[1].  Some of these checks
 125        may restrict the characters allowed in a branch name.
 126
 127<start-point>::
 128        The new branch will be created with a HEAD equal to this.  It may
 129        be given as a branch name, a commit-id, or a tag.  If this option
 130        is omitted, the current branch is assumed.
 131
 132<oldbranch>::
 133        The name of an existing branch to rename.
 134
 135<newbranch>::
 136        The new name for an existing branch. The same restrictions as for
 137        <branchname> applies.
 138

 140Examples
 141--------
 142
 143Start development off of a known tag::
 144+
 145------------
 146$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
 147$ cd my2.6
 148$ git branch my2.6.14 v2.6.14   <1>
 149$ git checkout my2.6.14
 150------------
 151+
 152<1> This step and the next one could be combined into a single step with
 153"checkout -b my2.6.14 v2.6.14".
 154
 155Delete unneeded branch::
 156+
 157------------
 158$ git clone git://git.kernel.org/.../git.git my.git
 159$ cd my.git
 160$ git branch -d -r origin/todo origin/html origin/man   <1>
 161$ git branch -D test                                    <2>
 162------------
 163+
 164<1> Delete remote-tracking branches "todo", "html", "man". Next 'fetch' or
 165'pull' will create them again unless you configure them not to. See
 166linkgit:git-fetch[1].
 167<2> Delete "test" branch even if the "master" branch (or whichever branch is
 168currently checked out) does not have all commits from test branch.
 169

 171Notes
 172-----
 173
 174If you are creating a branch that you want to immediately checkout, it's
 175easier to use the git checkout command with its `-b` option to create
 176a branch and check it out with a single command.
