  20DESCRIPTION
  21-----------
  22
  23With no arguments, existing branches are listed and the current branch will
  24be highlighted with an asterisk.  Option `-r` causes the remote-tracking
  25branches to be listed, and option `-a` shows both. This list mode is also
  26activated by the `--list` option (see below).
  27<pattern> restricts the output to matching branches, the pattern is a shell
  28wildcard (i.e., matched using fnmatch(3)).
  29Multiple patterns may be given; if any of them matches, the branch is shown.
  30
  31With `--contains`, shows only the branches that contain the named commit
  32(in other words, the branches whose tip commits are descendants of the
  33named commit).  With `--merged`, only branches merged into the named
  34commit (i.e. the branches whose tip commits are reachable from the named
  35commit) will be listed.  With `--no-merged` only branches not merged into
  36the named commit will be listed.  If the <commit> argument is missing it
  37defaults to 'HEAD' (i.e. the tip of the current branch).
  38
  39The command's second form creates a new branch head named <branchname>
  40which points to the current 'HEAD', or <start-point> if given.
  41
  42Note that this will create the new branch, but it will not switch the
  43working tree to it; use "git checkout <newbranch>" to switch to the
  44new branch.
  45
  46When a local branch is started off a remote-tracking branch, git sets up the
  47branch so that 'git pull' will appropriately merge from
  48the remote-tracking branch. This behavior may be changed via the global
  49`branch.autosetupmerge` configuration flag. That setting can be
  50overridden by using the `--track` and `--no-track` options, and
  51changed later using `git branch --set-upstream`.
  52
  53With a `-m` or `-M` option, <oldbranch> will be renamed to <newbranch>.
  54If <oldbranch> had a corresponding reflog, it is renamed to match
  55<newbranch>, and a reflog entry is created to remember the branch
  56renaming. If <newbranch> exists, -M must be used to force the rename
  57to happen.
  58
  59With a `-d` or `-D` option, `<branchname>` will be deleted.  You may
  60specify more than one branch for deletion.  If the branch currently
  61has a reflog then the reflog will also be deleted.
  62
  63Use `-r` together with `-d` to delete remote-tracking branches. Note, that it
  64only makes sense to delete remote-tracking branches if they no longer exist
  65in the remote repository or if 'git fetch' was configured not to fetch
  66them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a
  67way to clean up all obsolete remote-tracking branches.
  68
  69
  70OPTIONS
  71-------
  72-d::
  73--delete::
  74        Delete a branch. The branch must be fully merged in its
  75        upstream branch, or in `HEAD` if no upstream was set with
  76        `--track` or `--set-upstream`.
  77
  78-D::
  79        Delete a branch irrespective of its merged status.
  80
  81-l::
  82--create-reflog::
  83        Create the branch's reflog.  This activates recording of
  84        all changes made to the branch ref, enabling use of date
  85        based sha1 expressions such as "<branchname>@\{yesterday}".
  86        Note that in non-bare repositories, reflogs are usually
  87        enabled by default by the `core.logallrefupdates` config option.
  88
  89-f::
  90--force::
  91        Reset <branchname> to <startpoint> if <branchname> exists
  92        already. Without `-f` 'git branch' refuses to change an existing branch.
  93
  94-m::
  95--move::
  96        Move/rename a branch and the corresponding reflog.
  97
  98-M::
  99        Move/rename a branch even if the new branch name already exists.
 100
 101--color[=<when>]::
 102        Color branches to highlight current, local, and
 103        remote-tracking branches.
 104        The value must be always (the default), never, or auto.
 105
 106--no-color::
 107        Turn off branch colors, even when the configuration file gives the
 108        default to color output.
 109        Same as `--color=never`.
 110
 111--column[=<options>]::
 112--no-column::
 113        Display branch listing in columns. See configuration variable
 114        column.branch for option syntax.`--column` and `--no-column`
 115        without options are equivalent to 'always' and 'never' respectively.
 116+
 117This option is only applicable in non-verbose mode.
 118
 119-r::
 120--remotes::
 121        List or delete (if used with -d) the remote-tracking branches.
 122
 123-a::
 124--all::
 125        List both remote-tracking branches and local branches.
 126
 127--list::
 128        Activate the list mode. `git branch <pattern>` would try to create a branch,
 129        use `git branch --list <pattern>` to list matching branches.
 130
 131-v::
 132--verbose::
 133        When in list mode,
 134        show sha1 and commit subject line for each head, along with
 135        relationship to upstream branch (if any). If given twice, print
 136        the name of the upstream branch, as well.
 137
 138-q::
 139--quiet::
 140        Be more quiet when creating or deleting a branch, suppressing
 141        non-error messages.
 142
 143--abbrev=<length>::
 144        Alter the sha1's minimum display length in the output listing.
 145        The default value is 7 and can be overridden by the `core.abbrev`
 146        config option.
 147
 148--no-abbrev::
 149        Display the full sha1s in the output listing rather than abbreviating them.
 150
 151-t::
 152--track::
 153        When creating a new branch, set up configuration to mark the
 154        start-point branch as "upstream" from the new branch. This
 155        configuration will tell git to show the relationship between the
 156        two branches in `git status` and `git branch -v`. Furthermore,
 157        it directs `git pull` without arguments to pull from the
 158        upstream when the new branch is checked out.
 159+
 160This behavior is the default when the start point is a remote-tracking branch.
 161Set the branch.autosetupmerge configuration variable to `false` if you
 162want `git checkout` and `git branch` to always behave as if '--no-track'
 163were given. Set it to `always` if you want this behavior when the
 164start-point is either a local or remote-tracking branch.
 165
 166--no-track::
 167        Do not set up "upstream" configuration, even if the
 168        branch.autosetupmerge configuration variable is true.
 169
 170--set-upstream::
 171        If specified branch does not exist yet or if `--force` has been
 172        given, acts exactly like `--track`. Otherwise sets up configuration
 173        like `--track` would when creating the branch, except that where
 174        branch points to is not changed.
 175
 176--edit-description::
 177        Open an editor and edit the text to explain what the branch is
 178        for, to be used by various other commands (e.g. `request-pull`).
 179
 180--contains [<commit>]::
 181        Only list branches which contain the specified commit (HEAD
 182        if not specified).
 183
 184--merged [<commit>]::
 185        Only list branches whose tips are reachable from the
 186        specified commit (HEAD if not specified).
 187
 188--no-merged [<commit>]::
 189        Only list branches whose tips are not reachable from the
 190        specified commit (HEAD if not specified).
 191
 192<branchname>::
 193        The name of the branch to create or delete.
 194        The new branch name must pass all checks defined by
 195        linkgit:git-check-ref-format[1].  Some of these checks
 196        may restrict the characters allowed in a branch name.
 197
 198<start-point>::
 199        The new branch head will point to this commit.  It may be
 200        given as a branch name, a commit-id, or a tag.  If this
 201        option is omitted, the current HEAD will be used instead.
 202
 203<oldbranch>::
 204        The name of an existing branch to rename.
 205
 206<newbranch>::
 207        The new name for an existing branch. The same restrictions as for
 208        <branchname> apply.
 209
 210
 211Examples
 212--------
 213
 214Start development from a known tag::
 215+
 216------------
 217$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
 218$ cd my2.6
 219$ git branch my2.6.14 v2.6.14   <1>
 220$ git checkout my2.6.14
 221------------
 222+
 223<1> This step and the next one could be combined into a single step with
 224"checkout -b my2.6.14 v2.6.14".
 225
 226Delete an unneeded branch::
 227+
 228------------
 229$ git clone git://git.kernel.org/.../git.git my.git
 230$ cd my.git
 231$ git branch -d -r origin/todo origin/html origin/man   <1>
 232$ git branch -D test                                    <2>
 233------------
 234+
 235<1> Delete the remote-tracking branches "todo", "html" and "man". The next
 236'fetch' or 'pull' will create them again unless you configure them not to.
 237See linkgit:git-fetch[1].
 238<2> Delete the "test" branch even if the "master" branch (or whichever branch
 239is currently checked out) does not have all commits from the test branch.
 240
 241
 242Notes
 243-----
 244
 245If you are creating a branch that you want to checkout immediately, it is
 246easier to use the git checkout command with its `-b` option to create
 247a branch and check it out with a single command.
 248
 249The options `--contains`, `--merged` and `--no-merged` serve three related
 250but different purposes:
 251
 252- `--contains <commit>` is used to find all branches which will need
 253  special attention if <commit> were to be rebased or amended, since those
 254  branches contain the specified <commit>.
 255
 256- `--merged` is used to find all branches which can be safely deleted,
 257  since those branches are fully contained by HEAD.
 258
 259- `--no-merged` is used to find branches which are candidates for merging
 260  into HEAD, since those branches are not fully contained by HEAD.
