  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+
 104The `-l` option is a deprecated synonym for `--create-reflog`.
 105
 106-f::
 107--force::
 108        Reset <branchname> to <startpoint>, even if <branchname> exists
 109        already. Without `-f`, 'git branch' refuses to change an existing branch.
 110        In combination with `-d` (or `--delete`), allow deleting the
 111        branch irrespective of its merged status. In combination with
 112        `-m` (or `--move`), allow renaming the branch even if the new
 113        branch name already exists, the same applies for `-c` (or `--copy`).
 114
 115-m::
 116--move::
 117        Move/rename a branch and the corresponding reflog.
 118
 119-M::
 120        Shortcut for `--move --force`.
 121
 122-c::
 123--copy::
 124        Copy a branch and the corresponding reflog.
 125
 126-C::
 127        Shortcut for `--copy --force`.
 128
 129--color[=<when>]::
 130        Color branches to highlight current, local, and
 131        remote-tracking branches.
 132        The value must be always (the default), never, or auto.
 133
 134--no-color::
 135        Turn off branch colors, even when the configuration file gives the
 136        default to color output.
 137        Same as `--color=never`.
 138
 139-i::
 140--ignore-case::
 141        Sorting and filtering branches are case insensitive.
 142
 143--column[=<options>]::
 144--no-column::
 145        Display branch listing in columns. See configuration variable
 146        column.branch for option syntax.`--column` and `--no-column`
 147        without options are equivalent to 'always' and 'never' respectively.
 148+
 149This option is only applicable in non-verbose mode.
 150
 151-r::
 152--remotes::
 153        List or delete (if used with -d) the remote-tracking branches.
 154
 155-a::
 156--all::
 157        List both remote-tracking branches and local branches.
 158
 159--list::
 160        List branches.  With optional `<pattern>...`, e.g. `git
 161        branch --list 'maint-*'`, list only the branches that match
 162        the pattern(s).
 163+
 164This should not be confused with `git branch -l <branchname>`,
 165which creates a branch named `<branchname>` with a reflog.
 166See `--create-reflog` above for details.
 167
 168-v::
 169-vv::
 170--verbose::
 171        When in list mode,
 172        show sha1 and commit subject line for each head, along with
 173        relationship to upstream branch (if any). If given twice, print
 174        the name of the upstream branch, as well (see also `git remote
 175        show <remote>`).
 176
 177-q::
 178--quiet::
 179        Be more quiet when creating or deleting a branch, suppressing
 180        non-error messages.
 181
 182--abbrev=<length>::
 183        Alter the sha1's minimum display length in the output listing.
 184        The default value is 7 and can be overridden by the `core.abbrev`
 185        config option.
 186
 187--no-abbrev::
 188        Display the full sha1s in the output listing rather than abbreviating them.
 189
 190-t::
 191--track::
 192        When creating a new branch, set up `branch.<name>.remote` and
 193        `branch.<name>.merge` configuration entries to mark the
 194        start-point branch as "upstream" from the new branch. This
 195        configuration will tell git to show the relationship between the
 196        two branches in `git status` and `git branch -v`. Furthermore,
 197        it directs `git pull` without arguments to pull from the
 198        upstream when the new branch is checked out.
 199+
 200This behavior is the default when the start point is a remote-tracking branch.
 201Set the branch.autoSetupMerge configuration variable to `false` if you
 202want `git checkout` and `git branch` to always behave as if `--no-track`
 203were given. Set it to `always` if you want this behavior when the
 204start-point is either a local or remote-tracking branch.
 205
 206--no-track::
 207        Do not set up "upstream" configuration, even if the
 208        branch.autoSetupMerge configuration variable is true.
 209
 210--set-upstream::
 211        As this option had confusing syntax, it is no longer supported.
 212        Please use `--track` or `--set-upstream-to` instead.
 213
 214-u <upstream>::
 215--set-upstream-to=<upstream>::
 216        Set up <branchname>'s tracking information so <upstream> is
 217        considered <branchname>'s upstream branch. If no <branchname>
 218        is specified, then it defaults to the current branch.
 219
 220--unset-upstream::
 221        Remove the upstream information for <branchname>. If no branch
 222        is specified it defaults to the current branch.
 223
 224--edit-description::
 225        Open an editor and edit the text to explain what the branch is
 226        for, to be used by various other commands (e.g. `format-patch`,
 227        `request-pull`, and `merge` (if enabled)). Multi-line explanations
 228        may be used.
 229
 230--contains [<commit>]::
 231        Only list branches which contain the specified commit (HEAD
 232        if not specified). Implies `--list`.
 233
 234--no-contains [<commit>]::
 235        Only list branches which don't contain the specified commit
 236        (HEAD if not specified). Implies `--list`.
 237
 238--merged [<commit>]::
 239        Only list branches whose tips are reachable from the
 240        specified commit (HEAD if not specified). Implies `--list`,
 241        incompatible with `--no-merged`.
 242
 243--no-merged [<commit>]::
 244        Only list branches whose tips are not reachable from the
 245        specified commit (HEAD if not specified). Implies `--list`,
 246        incompatible with `--merged`.
 247
 248<branchname>::
 249        The name of the branch to create or delete.
 250        The new branch name must pass all checks defined by
 251        linkgit:git-check-ref-format[1].  Some of these checks
 252        may restrict the characters allowed in a branch name.
 253
 254<start-point>::
 255        The new branch head will point to this commit.  It may be
 256        given as a branch name, a commit-id, or a tag.  If this
 257        option is omitted, the current HEAD will be used instead.
 258
 259<oldbranch>::
 260        The name of an existing branch to rename.
 261
 262<newbranch>::
 263        The new name for an existing branch. The same restrictions as for
 264        <branchname> apply.
 265
 266--sort=<key>::
 267        Sort based on the key given. Prefix `-` to sort in descending
 268        order of the value. You may use the --sort=<key> option
 269        multiple times, in which case the last key becomes the primary
 270        key. The keys supported are the same as those in `git
 271        for-each-ref`. Sort order defaults to the value configured for the
 272        `branch.sort` variable if exists, or to sorting based on the
 273        full refname (including `refs/...` prefix). This lists
 274        detached HEAD (if present) first, then local branches and
 275        finally remote-tracking branches. See linkgit:git-config[1].
 276
 277
 278--points-at <object>::
 279        Only list branches of the given object.
 280
 281--format <format>::
 282        A string that interpolates `%(fieldname)` from a branch ref being shown
 283        and the object it points at.  The format is the same as
 284        that of linkgit:git-for-each-ref[1].
 285
 286CONFIGURATION
 287-------------
 288`pager.branch` is only respected when listing branches, i.e., when
 289`--list` is used or implied. The default is to use a pager.
 290See linkgit:git-config[1].
 291
 292EXAMPLES
 293--------
 294
 295Start development from a known tag::
 296+
 297------------
 298$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
 299$ cd my2.6
 300$ git branch my2.6.14 v2.6.14   <1>
 301$ git checkout my2.6.14
 302------------
 303+
 304<1> This step and the next one could be combined into a single step with
 305"checkout -b my2.6.14 v2.6.14".
 306
 307Delete an unneeded branch::
 308+
 309------------
 310$ git clone git://git.kernel.org/.../git.git my.git
 311$ cd my.git
 312$ git branch -d -r origin/todo origin/html origin/man   <1>
 313$ git branch -D test                                    <2>
 314------------
 315+
 316<1> Delete the remote-tracking branches "todo", "html" and "man". The next
 317'fetch' or 'pull' will create them again unless you configure them not to.
 318See linkgit:git-fetch[1].
 319<2> Delete the "test" branch even if the "master" branch (or whichever branch
 320is currently checked out) does not have all commits from the test branch.
 321
 322
 323NOTES
 324-----
 325
 326If you are creating a branch that you want to checkout immediately, it is
 327easier to use the git checkout command with its `-b` option to create
 328a branch and check it out with a single command.
 329
 330The options `--contains`, `--no-contains`, `--merged` and `--no-merged`
 331serve four related but different purposes:
 332
 333- `--contains <commit>` is used to find all branches which will need
 334  special attention if <commit> were to be rebased or amended, since those
 335  branches contain the specified <commit>.
 336
 337- `--no-contains <commit>` is the inverse of that, i.e. branches that don't
 338  contain the specified <commit>.
 339
 340- `--merged` is used to find all branches which can be safely deleted,
 341  since those branches are fully contained by HEAD.
 342
 343- `--no-merged` is used to find branches which are candidates for merging
 344  into HEAD, since those branches are not fully contained by HEAD.
