  23DESCRIPTION
  24-----------
  25
  26If `--list` is given, or if there are no non-option arguments, existing
  27branches are listed; the current branch will be highlighted with an
  28asterisk.  Option `-r` causes the remote-tracking branches to be listed,
  29and option `-a` shows both local and remote branches. If a `<pattern>`
  30is given, it is used as a shell wildcard to restrict the output to
  31matching branches. If multiple patterns are given, a branch is shown if
  32it matches any of the patterns.  Note that when providing a
  33`<pattern>`, you must use `--list`; otherwise the command is interpreted
  34as branch creation.
  35
  36With `--contains`, shows only the branches that contain the named commit
  37(in other words, the branches whose tip commits are descendants of the
  38named commit).  With `--merged`, only branches merged into the named
  39commit (i.e. the branches whose tip commits are reachable from the named
  40commit) will be listed.  With `--no-merged` only branches not merged into
  41the named commit will be listed.  If the <commit> argument is missing it
  42defaults to 'HEAD' (i.e. the tip of the current branch).
  43
  44The command's second form creates a new branch head named <branchname>
  45which points to the current 'HEAD', or <start-point> if given.
  46
  47Note that this will create the new branch, but it will not switch the
  48working tree to it; use "git checkout <newbranch>" to switch to the
  49new branch.
  50
  51When a local branch is started off a remote-tracking branch, Git sets up the
  52branch (specifically the `branch.<name>.remote` and `branch.<name>.merge`
  53configuration entries) so that 'git pull' will appropriately merge from
  54the remote-tracking branch. This behavior may be changed via the global
  55`branch.autoSetupMerge` configuration flag. That setting can be
  56overridden by using the `--track` and `--no-track` options, and
  57changed later using `git branch --set-upstream-to`.
  58
  59With a `-m` or `-M` option, <oldbranch> will be renamed to <newbranch>.
  60If <oldbranch> had a corresponding reflog, it is renamed to match
  61<newbranch>, and a reflog entry is created to remember the branch
  62renaming. If <newbranch> exists, -M must be used to force the rename
  63to happen.
  64
  65With a `-d` or `-D` option, `<branchname>` will be deleted.  You may
  66specify more than one branch for deletion.  If the branch currently
  67has a reflog then the reflog will also be deleted.
  68
  69Use `-r` together with `-d` to delete remote-tracking branches. Note, that it
  70only makes sense to delete remote-tracking branches if they no longer exist
  71in the remote repository or if 'git fetch' was configured not to fetch
  72them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a
  73way to clean up all obsolete remote-tracking branches.
  74
  75
  76OPTIONS
  77-------
  78-d::
  79--delete::
  80        Delete a branch. The branch must be fully merged in its
  81        upstream branch, or in `HEAD` if no upstream was set with
  82        `--track` or `--set-upstream`.
  83
  84-D::
  85        Shortcut for `--delete --force`.
  86
  87-l::
  88--create-reflog::
  89        Create the branch's reflog.  This activates recording of
  90        all changes made to the branch ref, enabling use of date
  91        based sha1 expressions such as "<branchname>@\{yesterday}".
  92        Note that in non-bare repositories, reflogs are usually
  93        enabled by default by the `core.logallrefupdates` config option.
  94
  95-f::
  96--force::
  97        Reset <branchname> to <startpoint> if <branchname> exists
  98        already. Without `-f` 'git branch' refuses to change an existing branch.
  99        In combination with `-d` (or `--delete`), allow deleting the
 100        branch irrespective of its merged status. In combination with
 101        `-m` (or `--move`), allow renaming the branch even if the new
 102        branch name already exists.
 103
 104-m::
 105--move::
 106        Move/rename a branch and the corresponding reflog.
 107
 108-M::
 109        Shortcut for `--move --force`.
 110
 111--color[=<when>]::
 112        Color branches to highlight current, local, and
 113        remote-tracking branches.
 114        The value must be always (the default), never, or auto.
 115
 116--no-color::
 117        Turn off branch colors, even when the configuration file gives the
 118        default to color output.
 119        Same as `--color=never`.
 120
 121--column[=<options>]::
 122--no-column::
 123        Display branch listing in columns. See configuration variable
 124        column.branch for option syntax.`--column` and `--no-column`
 125        without options are equivalent to 'always' and 'never' respectively.
 126+
 127This option is only applicable in non-verbose mode.
 128
 129-r::
 130--remotes::
 131        List or delete (if used with -d) the remote-tracking branches.
 132
 133-a::
 134--all::
 135        List both remote-tracking branches and local branches.
 136
 137--list::
 138        Activate the list mode. `git branch <pattern>` would try to create a branch,
 139        use `git branch --list <pattern>` to list matching branches.
 140
 141-v::
 142-vv::
 143--verbose::
 144        When in list mode,
 145        show sha1 and commit subject line for each head, along with
 146        relationship to upstream branch (if any). If given twice, print
 147        the name of the upstream branch, as well (see also `git remote
 148        show <remote>`).
 149
 150-q::
 151--quiet::
 152        Be more quiet when creating or deleting a branch, suppressing
 153        non-error messages.
 154
 155--abbrev=<length>::
 156        Alter the sha1's minimum display length in the output listing.
 157        The default value is 7 and can be overridden by the `core.abbrev`
 158        config option.
 159
 160--no-abbrev::
 161        Display the full sha1s in the output listing rather than abbreviating them.
 162
 163-t::
 164--track::
 165        When creating a new branch, set up `branch.<name>.remote` and
 166        `branch.<name>.merge` configuration entries to mark the
 167        start-point branch as "upstream" from the new branch. This
 168        configuration will tell git to show the relationship between the
 169        two branches in `git status` and `git branch -v`. Furthermore,
 170        it directs `git pull` without arguments to pull from the
 171        upstream when the new branch is checked out.
 172+
 173This behavior is the default when the start point is a remote-tracking branch.
 174Set the branch.autoSetupMerge configuration variable to `false` if you
 175want `git checkout` and `git branch` to always behave as if '--no-track'
 176were given. Set it to `always` if you want this behavior when the
 177start-point is either a local or remote-tracking branch.
 178
 179--no-track::
 180        Do not set up "upstream" configuration, even if the
 181        branch.autoSetupMerge configuration variable is true.
 182
 183--set-upstream::
 184        If specified branch does not exist yet or if `--force` has been
 185        given, acts exactly like `--track`. Otherwise sets up configuration
 186        like `--track` would when creating the branch, except that where
 187        branch points to is not changed.
 188
 189-u <upstream>::
 190--set-upstream-to=<upstream>::
 191        Set up <branchname>'s tracking information so <upstream> is
 192        considered <branchname>'s upstream branch. If no <branchname>
 193        is specified, then it defaults to the current branch.
 194
 195--unset-upstream::
 196        Remove the upstream information for <branchname>. If no branch
 197        is specified it defaults to the current branch.
 198
 199--edit-description::
 200        Open an editor and edit the text to explain what the branch is
 201        for, to be used by various other commands (e.g. `format-patch`,
 202        `request-pull`, and `merge` (if enabled)). Multi-line explanations
 203        may be used.
 204
 205--contains [<commit>]::
 206        Only list branches which contain the specified commit (HEAD
 207        if not specified). Implies `--list`.
 208
 209--merged [<commit>]::
 210        Only list branches whose tips are reachable from the
 211        specified commit (HEAD if not specified). Implies `--list`.
 212
 213--no-merged [<commit>]::
 214        Only list branches whose tips are not reachable from the
 215        specified commit (HEAD if not specified). Implies `--list`.
 216
 217<branchname>::
 218        The name of the branch to create or delete.
 219        The new branch name must pass all checks defined by
 220        linkgit:git-check-ref-format[1].  Some of these checks
 221        may restrict the characters allowed in a branch name.
 222
 223<start-point>::
 224        The new branch head will point to this commit.  It may be
 225        given as a branch name, a commit-id, or a tag.  If this
 226        option is omitted, the current HEAD will be used instead.
 227
 228<oldbranch>::
 229        The name of an existing branch to rename.
 230
 231<newbranch>::
 232        The new name for an existing branch. The same restrictions as for
 233        <branchname> apply.
 234
 235--sort=<key>::
 236        Sort based on the key given. Prefix `-` to sort in descending
 237        order of the value. You may use the --sort=<key> option
 238        multiple times, in which case the last key becomes the primary
 239        key. The keys supported are the same as those in `git
 240        for-each-ref`. Sort order defaults to sorting based on the
 241        full refname (including `refs/...` prefix). This lists
 242        detached HEAD (if present) first, then local branches and
 243        finally remote-tracking branches.
 244
 245
 246--points-at <object>::
 247        Only list branches of the given object.
 248
 249Examples
 250--------
 251
 252Start development from a known tag::
 253+
 254------------
 255$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
 256$ cd my2.6
 257$ git branch my2.6.14 v2.6.14   <1>
 258$ git checkout my2.6.14
 259------------
 260+
 261<1> This step and the next one could be combined into a single step with
 262"checkout -b my2.6.14 v2.6.14".
 263
 264Delete an unneeded branch::
 265+
 266------------
 267$ git clone git://git.kernel.org/.../git.git my.git
 268$ cd my.git
 269$ git branch -d -r origin/todo origin/html origin/man   <1>
 270$ git branch -D test                                    <2>
 271------------
 272+
 273<1> Delete the remote-tracking branches "todo", "html" and "man". The next
 274'fetch' or 'pull' will create them again unless you configure them not to.
 275See linkgit:git-fetch[1].
 276<2> Delete the "test" branch even if the "master" branch (or whichever branch
 277is currently checked out) does not have all commits from the test branch.
 278
 279
 280Notes
 281-----
 282
 283If you are creating a branch that you want to checkout immediately, it is
 284easier to use the git checkout command with its `-b` option to create
 285a branch and check it out with a single command.
 286
 287The options `--contains`, `--merged` and `--no-merged` serve three related
 288but different purposes:
 289
 290- `--contains <commit>` is used to find all branches which will need
 291  special attention if <commit> were to be rebased or amended, since those
 292  branches contain the specified <commit>.
 293
 294- `--merged` is used to find all branches which can be safely deleted,
 295  since those branches are fully contained by HEAD.
 296
 297- `--no-merged` is used to find branches which are candidates for merging
 298  into HEAD, since those branches are not fully contained by HEAD.
