22 DESCRIPTION
23 -----------
24
25 With no arguments, existing branches are listed and the current branch will
26 be highlighted with an asterisk. Option `-r` causes the remote-tracking
27 branches to be listed, and option `-a` shows both. This list mode is also
28 activated by the `--list` option (see below).
29 <pattern> restricts the output to matching branches, the pattern is a shell
30 wildcard (i.e., matched using fnmatch(3)).
31 Multiple patterns may be given; if any of them matches, the branch is shown.
32
33 With `--contains`, shows only the branches that contain the named commit
34 (in other words, the branches whose tip commits are descendants of the
35 named commit). With `--merged`, only branches merged into the named
36 commit (i.e. the branches whose tip commits are reachable from the named
37 commit) will be listed. With `--no-merged` only branches not merged into
38 the named commit will be listed. If the <commit> argument is missing it
39 defaults to 'HEAD' (i.e. the tip of the current branch).
40
41 The command's second form creates a new branch head named <branchname>
42 which points to the current 'HEAD', or <start-point> if given.
43
44 Note that this will create the new branch, but it will not switch the
45 working tree to it; use "git checkout <newbranch>" to switch to the
46 new branch.
47
48 When a local branch is started off a remote-tracking branch, git sets up the
49 branch so that 'git pull' will appropriately merge from
50 the remote-tracking branch. This behavior may be changed via the global
51 `branch.autosetupmerge` configuration flag. That setting can be
52 overridden by using the `--track` and `--no-track` options, and
53 changed later using `git branch --set-upstream-to`.
54
55 With a `-m` or `-M` option, <oldbranch> will be renamed to <newbranch>.
56 If <oldbranch> had a corresponding reflog, it is renamed to match
57 <newbranch>, and a reflog entry is created to remember the branch
58 renaming. If <newbranch> exists, -M must be used to force the rename
59 to happen.
60
61 With a `-d` or `-D` option, `<branchname>` will be deleted. You may
62 specify more than one branch for deletion. If the branch currently
63 has a reflog then the reflog will also be deleted.
64
65 Use `-r` together with `-d` to delete remote-tracking branches. Note, that it
66 only makes sense to delete remote-tracking branches if they no longer exist
67 in the remote repository or if 'git fetch' was configured not to fetch
68 them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a
69 way to clean up all obsolete remote-tracking branches.
70
71
72 OPTIONS
73 -------
74 -d::
75 --delete::
76 Delete a branch. The branch must be fully merged in its
77 upstream branch, or in `HEAD` if no upstream was set with
78 `--track` or `--set-upstream`.
79
80 -D::
81 Delete a branch irrespective of its merged status.
82
83 -l::
84 --create-reflog::
85 Create the branch's reflog. This activates recording of
86 all changes made to the branch ref, enabling use of date
87 based sha1 expressions such as "<branchname>@\{yesterday}".
88 Note that in non-bare repositories, reflogs are usually
89 enabled by default by the `core.logallrefupdates` config option.
90
91 -f::
92 --force::
93 Reset <branchname> to <startpoint> if <branchname> exists
94 already. Without `-f` 'git branch' refuses to change an existing branch.
95
96 -m::
97 --move::
98 Move/rename a branch and the corresponding reflog.
99
100 -M::
101 Move/rename a branch even if the new branch name already exists.
102
103 --color[=<when>]::
104 Color branches to highlight current, local, and
105 remote-tracking branches.
106 The value must be always (the default), never, or auto.
107
108 --no-color::
109 Turn off branch colors, even when the configuration file gives the
110 default to color output.
111 Same as `--color=never`.
112
113 --column[=<options>]::
114 --no-column::
115 Display branch listing in columns. See configuration variable
116 column.branch for option syntax.`--column` and `--no-column`
117 without options are equivalent to 'always' and 'never' respectively.
118 +
119 This option is only applicable in non-verbose mode.
120
121 -r::
122 --remotes::
123 List or delete (if used with -d) the remote-tracking branches.
124
125 -a::
126 --all::
127 List both remote-tracking branches and local branches.
128
129 --list::
130 Activate the list mode. `git branch <pattern>` would try to create a branch,
131 use `git branch --list <pattern>` to list matching branches.
132
133 -v::
134 -vv::
135 --verbose::
136 When in list mode,
137 show sha1 and commit subject line for each head, along with
138 relationship to upstream branch (if any). If given twice, print
139 the name of the upstream branch, as well (see also `git remote
140 show <remote>`).
141
142 -q::
143 --quiet::
144 Be more quiet when creating or deleting a branch, suppressing
145 non-error messages.
146
147 --abbrev=<length>::
148 Alter the sha1's minimum display length in the output listing.
149 The default value is 7 and can be overridden by the `core.abbrev`
150 config option.
151
152 --no-abbrev::
153 Display the full sha1s in the output listing rather than abbreviating them.
154
155 -t::
156 --track::
157 When creating a new branch, set up configuration to mark the
158 start-point branch as "upstream" from the new branch. This
159 configuration will tell git to show the relationship between the
160 two branches in `git status` and `git branch -v`. Furthermore,
161 it directs `git pull` without arguments to pull from the
162 upstream when the new branch is checked out.
163 +
164 This behavior is the default when the start point is a remote-tracking branch.
165 Set the branch.autosetupmerge configuration variable to `false` if you
166 want `git checkout` and `git branch` to always behave as if '--no-track'
167 were given. Set it to `always` if you want this behavior when the
168 start-point is either a local or remote-tracking branch.
169
170 --no-track::
171 Do not set up "upstream" configuration, even if the
172 branch.autosetupmerge configuration variable is true.
173
174 --set-upstream::
175 If specified branch does not exist yet or if `--force` has been
176 given, acts exactly like `--track`. Otherwise sets up configuration
177 like `--track` would when creating the branch, except that where
178 branch points to is not changed.
179
180 -u <upstream>::
181 --set-upstream-to=<upstream>::
182 Set up <branchname>'s tracking information so <upstream> is
183 considered <branchname>'s upstream branch. If no <branchname>
184 is specified, then it defaults to the current branch.
185
186 --unset-upstream::
187 Remove the upstream information for <branchname>. If no branch
188 is specified it defaults to the current branch.
189
190 --edit-description::
191 Open an editor and edit the text to explain what the branch is
192 for, to be used by various other commands (e.g. `request-pull`).
193
194 --contains [<commit>]::
195 Only list branches which contain the specified commit (HEAD
196 if not specified).
197
198 --merged [<commit>]::
199 Only list branches whose tips are reachable from the
200 specified commit (HEAD if not specified).
201
202 --no-merged [<commit>]::
203 Only list branches whose tips are not reachable from the
204 specified commit (HEAD if not specified).
205
206 <branchname>::
207 The name of the branch to create or delete.
208 The new branch name must pass all checks defined by
209 linkgit:git-check-ref-format[1]. Some of these checks
210 may restrict the characters allowed in a branch name.
211
212 <start-point>::
213 The new branch head will point to this commit. It may be
214 given as a branch name, a commit-id, or a tag. If this
215 option is omitted, the current HEAD will be used instead.
216
217 <oldbranch>::
218 The name of an existing branch to rename.
219
220 <newbranch>::
221 The new name for an existing branch. The same restrictions as for
222 <branchname> apply.
223
224
225 Examples
226 --------
227
228 Start development from a known tag::
229 +
230 ------------
231 $ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
232 $ cd my2.6
233 $ git branch my2.6.14 v2.6.14 <1>
234 $ git checkout my2.6.14
235 ------------
236 +
237 <1> This step and the next one could be combined into a single step with
238 "checkout -b my2.6.14 v2.6.14".
239
240 Delete an unneeded branch::
241 +
242 ------------
243 $ git clone git://git.kernel.org/.../git.git my.git
244 $ cd my.git
245 $ git branch -d -r origin/todo origin/html origin/man <1>
246 $ git branch -D test <2>
247 ------------
248 +
249 <1> Delete the remote-tracking branches "todo", "html" and "man". The next
250 'fetch' or 'pull' will create them again unless you configure them not to.
251 See linkgit:git-fetch[1].
252 <2> Delete the "test" branch even if the "master" branch (or whichever branch
253 is currently checked out) does not have all commits from the test branch.
254
255
256 Notes
257 -----
258
259 If you are creating a branch that you want to checkout immediately, it is
260 easier to use the git checkout command with its `-b` option to create
261 a branch and check it out with a single command.
262
263 The options `--contains`, `--merged` and `--no-merged` serve three related
264 but different purposes:
265
266 - `--contains <commit>` is used to find all branches which will need
267 special attention if <commit> were to be rebased or amended, since those
268 branches contain the specified <commit>.
269
270 - `--merged` is used to find all branches which can be safely deleted,
271 since those branches are fully contained by HEAD.
272
273 - `--no-merged` is used to find branches which are candidates for merging
274 into HEAD, since those branches are not fully contained by HEAD.
