  19DESCRIPTION
  20-----------
  21
  22With no arguments, existing branches are listed and the current branch will
  23be highlighted with an asterisk.  Option `-r` causes the remote-tracking
  24branches to be listed, and option `-a` shows both.
  25
  26With `--contains`, shows only the branches that contain the named commit
  27(in other words, the branches whose tip commits are descendants of the
  28named commit).  With `--merged`, only branches merged into the named
  29commit (i.e. the branches whose tip commits are reachable from the named
  30commit) will be listed.  With `--no-merged` only branches not merged into
  31the named commit will be listed.  If the <commit> argument is missing it
  32defaults to 'HEAD' (i.e. the tip of the current branch).
  33
  34The command's second form creates a new branch head named <branchname>
  35which points to the current 'HEAD', or <start-point> if given.
  36
  37Note that this will create the new branch, but it will not switch the
  38working tree to it; use "git checkout <newbranch>" to switch to the
  39new branch.
  40
  41When a local branch is started off a remote-tracking branch, git sets up the
  42branch so that 'git pull' will appropriately merge from
  43the remote-tracking branch. This behavior may be changed via the global
  44`branch.autosetupmerge` configuration flag. That setting can be
  45overridden by using the `--track` and `--no-track` options, and
  46changed later using `git branch --set-upstream`.
  47
  48With a '-m' or '-M' option, <oldbranch> will be renamed to <newbranch>.
  49If <oldbranch> had a corresponding reflog, it is renamed to match
  50<newbranch>, and a reflog entry is created to remember the branch
  51renaming. If <newbranch> exists, -M must be used to force the rename
  52to happen.
  53
  54With a `-d` or `-D` option, `<branchname>` will be deleted.  You may
  55specify more than one branch for deletion.  If the branch currently
  56has a reflog then the reflog will also be deleted.
  57
  58Use -r together with -d to delete remote-tracking branches. Note, that it
  59only makes sense to delete remote-tracking branches if they no longer exist
  60in the remote repository or if 'git fetch' was configured not to fetch
  61them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a
  62way to clean up all obsolete remote-tracking branches.
  63
  64
  65OPTIONS
  66-------
  67-d::
  68        Delete a branch. The branch must be fully merged in its
  69        upstream branch, or in `HEAD` if no upstream was set with
  70        `--track` or `--set-upstream`.
  71
  72-D::
  73        Delete a branch irrespective of its merged status.
  74
  75-l::
  76        Create the branch's reflog.  This activates recording of
  77        all changes made to the branch ref, enabling use of date
  78        based sha1 expressions such as "<branchname>@\{yesterday}".
  79        Note that in non-bare repositories, reflogs are usually
  80        enabled by default by the `core.logallrefupdates` config option.
  81
  82-f::
  83--force::
  84        Reset <branchname> to <startpoint> if <branchname> exists
  85        already. Without `-f` 'git branch' refuses to change an existing branch.
  86
  87-m::
  88        Move/rename a branch and the corresponding reflog.
  89
  90-M::
  91        Move/rename a branch even if the new branch name already exists.
  92
  93--color[=<when>]::
  94        Color branches to highlight current, local, and
  95        remote-tracking branches.
  96        The value must be always (the default), never, or auto.
  97
  98--no-color::
  99        Turn off branch colors, even when the configuration file gives the
 100        default to color output.
 101        Same as `--color=never`.
 102
 103-r::
 104        List or delete (if used with -d) the remote-tracking branches.
 105
 106-a::
 107        List both remote-tracking branches and local branches.
 108
 109-v::
 110--verbose::
 111        Show sha1 and commit subject line for each head, along with
 112        relationship to upstream branch (if any). If given twice, print
 113        the name of the upstream branch, as well.
 114
 115--abbrev=<length>::
 116        Alter the sha1's minimum display length in the output listing.
 117        The default value is 7 and can be overridden by the `core.abbrev`
 118        config option.
 119
 120--no-abbrev::
 121        Display the full sha1s in the output listing rather than abbreviating them.
 122
 123-t::
 124--track::
 125        When creating a new branch, set up configuration to mark the
 126        start-point branch as "upstream" from the new branch. This
 127        configuration will tell git to show the relationship between the
 128        two branches in `git status` and `git branch -v`. Furthermore,
 129        it directs `git pull` without arguments to pull from the
 130        upstream when the new branch is checked out.
 131+
 132This behavior is the default when the start point is a remote-tracking branch.
 133Set the branch.autosetupmerge configuration variable to `false` if you
 134want `git checkout` and `git branch` to always behave as if '--no-track'
 135were given. Set it to `always` if you want this behavior when the
 136start-point is either a local or remote-tracking branch.
 137
 138--no-track::
 139        Do not set up "upstream" configuration, even if the
 140        branch.autosetupmerge configuration variable is true.
 141
 142--set-upstream::
 143        If specified branch does not exist yet or if '--force' has been
 144        given, acts exactly like '--track'. Otherwise sets up configuration
 145        like '--track' would when creating the branch, except that where
 146        branch points to is not changed.
 147
 148--edit-description::
 149        Open an editor and edit the text to explain what the branch is
 150        for, to be used by various other commands (e.g. `request-pull`).
 151
 152--contains <commit>::
 153        Only list branches which contain the specified commit.
 154
 155--merged [<commit>]::
 156        Only list branches whose tips are reachable from the
 157        specified commit (HEAD if not specified).
 158
 159--no-merged [<commit>]::
 160        Only list branches whose tips are not reachable from the
 161        specified commit (HEAD if not specified).
 162
 163<branchname>::
 164        The name of the branch to create or delete.
 165        The new branch name must pass all checks defined by
 166        linkgit:git-check-ref-format[1].  Some of these checks
 167        may restrict the characters allowed in a branch name.
 168
 169<start-point>::
 170        The new branch head will point to this commit.  It may be
 171        given as a branch name, a commit-id, or a tag.  If this
 172        option is omitted, the current HEAD will be used instead.
 173
 174<oldbranch>::
 175        The name of an existing branch to rename.
 176
 177<newbranch>::
 178        The new name for an existing branch. The same restrictions as for
 179        <branchname> apply.
 180

 182Examples
 183--------
 184
 185Start development from a known tag::
 186+
 187------------
 188$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
 189$ cd my2.6
 190$ git branch my2.6.14 v2.6.14   <1>
 191$ git checkout my2.6.14
 192------------
 193+
 194<1> This step and the next one could be combined into a single step with
 195"checkout -b my2.6.14 v2.6.14".
 196
 197Delete an unneeded branch::
 198+
 199------------
 200$ git clone git://git.kernel.org/.../git.git my.git
 201$ cd my.git
 202$ git branch -d -r origin/todo origin/html origin/man   <1>
 203$ git branch -D test                                    <2>
 204------------
 205+
 206<1> Delete the remote-tracking branches "todo", "html" and "man". The next
 207'fetch' or 'pull' will create them again unless you configure them not to.
 208See linkgit:git-fetch[1].
 209<2> Delete the "test" branch even if the "master" branch (or whichever branch
 210is currently checked out) does not have all commits from the test branch.
 211
 212
 213Notes
 214-----
 215
 216If you are creating a branch that you want to checkout immediately, it is
 217easier to use the git checkout command with its `-b` option to create
 218a branch and check it out with a single command.
 219
 220The options `--contains`, `--merged` and `--no-merged` serve three related
 221but different purposes:
 222
 223- `--contains <commit>` is used to find all branches which will need
 224  special attention if <commit> were to be rebased or amended, since those
 225  branches contain the specified <commit>.
 226
 227- `--merged` is used to find all branches which can be safely deleted,
 228  since those branches are fully contained by HEAD.
 229
 230- `--no-merged` is used to find branches which are candidates for merging
 231  into HEAD, since those branches are not fully contained by HEAD.
