  25DESCRIPTION
  26-----------
  27
  28If `--list` is given, or if there are no non-option arguments, existing
  29branches are listed; the current branch will be highlighted with an
  30asterisk.  Option `-r` causes the remote-tracking branches to be listed,
  31and option `-a` shows both local and remote branches. If a `<pattern>`
  32is given, it is used as a shell wildcard to restrict the output to
  33matching branches. If multiple patterns are given, a branch is shown if
  34it matches any of the patterns.  Note that when providing a
  35`<pattern>`, you must use `--list`; otherwise the command is interpreted
  36as branch creation.
  37
  38With `--contains`, shows only the branches that contain the named commit
  39(in other words, the branches whose tip commits are descendants of the
  40named commit), `--no-contains` inverts it. With `--merged`, only branches
  41merged into the named commit (i.e. the branches whose tip commits are
  42reachable from the named commit) will be listed.  With `--no-merged` only
  43branches not merged into the named commit will be listed.  If the <commit>
  44argument is missing it defaults to `HEAD` (i.e. the tip of the current
  45branch).
  46
  47The command's second form creates a new branch head named <branchname>
  48which points to the current `HEAD`, or <start-point> if given.
  49
  50Note that this will create the new branch, but it will not switch the
  51working tree to it; use "git checkout <newbranch>" to switch to the
  52new branch.
  53
  54When a local branch is started off a remote-tracking branch, Git sets up the
  55branch (specifically the `branch.<name>.remote` and `branch.<name>.merge`
  56configuration entries) so that 'git pull' will appropriately merge from
  57the remote-tracking branch. This behavior may be changed via the global
  58`branch.autoSetupMerge` configuration flag. That setting can be
  59overridden by using the `--track` and `--no-track` options, and
  60changed later using `git branch --set-upstream-to`.
  61
  62With a `-m` or `-M` option, <oldbranch> will be renamed to <newbranch>.
  63If <oldbranch> had a corresponding reflog, it is renamed to match
  64<newbranch>, and a reflog entry is created to remember the branch
  65renaming. If <newbranch> exists, -M must be used to force the rename
  66to happen.
  67
  68The `-c` and `-C` options have the exact same semantics as `-m` and
  69`-M`, except instead of the branch being renamed it along with its
  70config and reflog will be copied to a new name.
  71
  72With a `-d` or `-D` option, `<branchname>` will be deleted.  You may
  73specify more than one branch for deletion.  If the branch currently
  74has a reflog then the reflog will also be deleted.
  75
  76Use `-r` together with `-d` to delete remote-tracking branches. Note, that it
  77only makes sense to delete remote-tracking branches if they no longer exist
  78in the remote repository or if 'git fetch' was configured not to fetch
  79them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a
  80way to clean up all obsolete remote-tracking branches.
  81
  82
  83OPTIONS
  84-------
  85-d::
  86--delete::
  87        Delete a branch. The branch must be fully merged in its
  88        upstream branch, or in `HEAD` if no upstream was set with
  89        `--track` or `--set-upstream-to`.
  90
  91-D::
  92        Shortcut for `--delete --force`.
  93
  94--create-reflog::
  95        Create the branch's reflog.  This activates recording of
  96        all changes made to the branch ref, enabling use of date
  97        based sha1 expressions such as "<branchname>@\{yesterday}".
  98        Note that in non-bare repositories, reflogs are usually
  99        enabled by default by the `core.logAllRefUpdates` config option.
 100        The negated form `--no-create-reflog` only overrides an earlier
 101        `--create-reflog`, but currently does not negate the setting of
 102        `core.logAllRefUpdates`.
 103
 104-f::
 105--force::
 106        Reset <branchname> to <startpoint>, even if <branchname> exists
 107        already. Without `-f`, 'git branch' refuses to change an existing branch.
 108        In combination with `-d` (or `--delete`), allow deleting the
 109        branch irrespective of its merged status. In combination with
 110        `-m` (or `--move`), allow renaming the branch even if the new
 111        branch name already exists, the same applies for `-c` (or `--copy`).
 112
 113-m::
 114--move::
 115        Move/rename a branch and the corresponding reflog.
 116
 117-M::
 118        Shortcut for `--move --force`.
 119
 120-c::
 121--copy::
 122        Copy a branch and the corresponding reflog.
 123
 124-C::
 125        Shortcut for `--copy --force`.
 126
 127--color[=<when>]::
 128        Color branches to highlight current, local, and
 129        remote-tracking branches.
 130        The value must be always (the default), never, or auto.
 131
 132--no-color::
 133        Turn off branch colors, even when the configuration file gives the
 134        default to color output.
 135        Same as `--color=never`.
 136
 137-i::
 138--ignore-case::
 139        Sorting and filtering branches are case insensitive.
 140
 141--column[=<options>]::
 142--no-column::
 143        Display branch listing in columns. See configuration variable
 144        column.branch for option syntax.`--column` and `--no-column`
 145        without options are equivalent to 'always' and 'never' respectively.
 146+
 147This option is only applicable in non-verbose mode.
 148
 149-r::
 150--remotes::
 151        List or delete (if used with -d) the remote-tracking branches.
 152
 153-a::
 154--all::
 155        List both remote-tracking branches and local branches.
 156
 157-l::
 158--list::
 159        List branches.  With optional `<pattern>...`, e.g. `git
 160        branch --list 'maint-*'`, list only the branches that match
 161        the pattern(s).
 162
 163-v::
 164-vv::
 165--verbose::
 166        When in list mode,
 167        show sha1 and commit subject line for each head, along with
 168        relationship to upstream branch (if any). If given twice, print
 169        the name of the upstream branch, as well (see also `git remote
 170        show <remote>`).
 171
 172-q::
 173--quiet::
 174        Be more quiet when creating or deleting a branch, suppressing
 175        non-error messages.
 176
 177--abbrev=<length>::
 178        Alter the sha1's minimum display length in the output listing.
 179        The default value is 7 and can be overridden by the `core.abbrev`
 180        config option.
 181
 182--no-abbrev::
 183        Display the full sha1s in the output listing rather than abbreviating them.
 184
 185-t::
 186--track::
 187        When creating a new branch, set up `branch.<name>.remote` and
 188        `branch.<name>.merge` configuration entries to mark the
 189        start-point branch as "upstream" from the new branch. This
 190        configuration will tell git to show the relationship between the
 191        two branches in `git status` and `git branch -v`. Furthermore,
 192        it directs `git pull` without arguments to pull from the
 193        upstream when the new branch is checked out.
 194+
 195This behavior is the default when the start point is a remote-tracking branch.
 196Set the branch.autoSetupMerge configuration variable to `false` if you
 197want `git checkout` and `git branch` to always behave as if `--no-track`
 198were given. Set it to `always` if you want this behavior when the
 199start-point is either a local or remote-tracking branch.
 200
 201--no-track::
 202        Do not set up "upstream" configuration, even if the
 203        branch.autoSetupMerge configuration variable is true.
 204
 205--set-upstream::
 206        As this option had confusing syntax, it is no longer supported.
 207        Please use `--track` or `--set-upstream-to` instead.
 208
 209-u <upstream>::
 210--set-upstream-to=<upstream>::
 211        Set up <branchname>'s tracking information so <upstream> is
 212        considered <branchname>'s upstream branch. If no <branchname>
 213        is specified, then it defaults to the current branch.
 214
 215--unset-upstream::
 216        Remove the upstream information for <branchname>. If no branch
 217        is specified it defaults to the current branch.
 218
 219--edit-description::
 220        Open an editor and edit the text to explain what the branch is
 221        for, to be used by various other commands (e.g. `format-patch`,
 222        `request-pull`, and `merge` (if enabled)). Multi-line explanations
 223        may be used.
 224
 225--contains [<commit>]::
 226        Only list branches which contain the specified commit (HEAD
 227        if not specified). Implies `--list`.
 228
 229--no-contains [<commit>]::
 230        Only list branches which don't contain the specified commit
 231        (HEAD if not specified). Implies `--list`.
 232
 233--merged [<commit>]::
 234        Only list branches whose tips are reachable from the
 235        specified commit (HEAD if not specified). Implies `--list`,
 236        incompatible with `--no-merged`.
 237
 238--no-merged [<commit>]::
 239        Only list branches whose tips are not reachable from the
 240        specified commit (HEAD if not specified). Implies `--list`,
 241        incompatible with `--merged`.
 242
 243<branchname>::
 244        The name of the branch to create or delete.
 245        The new branch name must pass all checks defined by
 246        linkgit:git-check-ref-format[1].  Some of these checks
 247        may restrict the characters allowed in a branch name.
 248
 249<start-point>::
 250        The new branch head will point to this commit.  It may be
 251        given as a branch name, a commit-id, or a tag.  If this
 252        option is omitted, the current HEAD will be used instead.
 253
 254<oldbranch>::
 255        The name of an existing branch to rename.
 256
 257<newbranch>::
 258        The new name for an existing branch. The same restrictions as for
 259        <branchname> apply.
 260
 261--sort=<key>::
 262        Sort based on the key given. Prefix `-` to sort in descending
 263        order of the value. You may use the --sort=<key> option
 264        multiple times, in which case the last key becomes the primary
 265        key. The keys supported are the same as those in `git
 266        for-each-ref`. Sort order defaults to the value configured for the
 267        `branch.sort` variable if exists, or to sorting based on the
 268        full refname (including `refs/...` prefix). This lists
 269        detached HEAD (if present) first, then local branches and
 270        finally remote-tracking branches. See linkgit:git-config[1].
 271
 272
 273--points-at <object>::
 274        Only list branches of the given object.
 275
 276--format <format>::
 277        A string that interpolates `%(fieldname)` from a branch ref being shown
 278        and the object it points at.  The format is the same as
 279        that of linkgit:git-for-each-ref[1].
 280
 281CONFIGURATION
 282-------------
 283`pager.branch` is only respected when listing branches, i.e., when
 284`--list` is used or implied. The default is to use a pager.
 285See linkgit:git-config[1].
 286
 287EXAMPLES
 288--------
 289
 290Start development from a known tag::
 291+
 292------------
 293$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
 294$ cd my2.6
 295$ git branch my2.6.14 v2.6.14   <1>
 296$ git checkout my2.6.14
 297------------
 298+
 299<1> This step and the next one could be combined into a single step with
 300    "checkout -b my2.6.14 v2.6.14".
 301
 302Delete an unneeded branch::
 303+
 304------------
 305$ git clone git://git.kernel.org/.../git.git my.git
 306$ cd my.git
 307$ git branch -d -r origin/todo origin/html origin/man   <1>
 308$ git branch -D test                                    <2>
 309------------
 310+
 311<1> Delete the remote-tracking branches "todo", "html" and "man". The next
 312    'fetch' or 'pull' will create them again unless you configure them not to.
 313    See linkgit:git-fetch[1].
 314<2> Delete the "test" branch even if the "master" branch (or whichever branch
 315    is currently checked out) does not have all commits from the test branch.
 316
 317
 318NOTES
 319-----
 320
 321If you are creating a branch that you want to checkout immediately, it is
 322easier to use the git checkout command with its `-b` option to create
 323a branch and check it out with a single command.
 324
 325The options `--contains`, `--no-contains`, `--merged` and `--no-merged`
 326serve four related but different purposes:
 327
 328- `--contains <commit>` is used to find all branches which will need
 329  special attention if <commit> were to be rebased or amended, since those
 330  branches contain the specified <commit>.
 331
 332- `--no-contains <commit>` is the inverse of that, i.e. branches that don't
 333  contain the specified <commit>.
 334
 335- `--merged` is used to find all branches which can be safely deleted,
 336  since those branches are fully contained by HEAD.
 337
 338- `--no-merged` is used to find branches which are candidates for merging
 339  into HEAD, since those branches are not fully contained by HEAD.
