18DESCRIPTION
19-----------
049716b3 20
e5ac1217 21With no arguments, existing branches are listed and the current branch will
049716b3
JH
22be highlighted with an asterisk. Option `-r` causes the remote-tracking
23branches to be listed, and option `-a` shows both.
24
e5ac1217
DM
25With `--contains`, shows only the branches that contain the named commit
26(in other words, the branches whose tip commits are descendants of the
049716b3
JH
27named commit). With `--merged`, only branches merged into the named
28commit (i.e. the branches whose tip commits are reachable from the named
29commit) will be listed. With `--no-merged` only branches not merged into
e5ac1217
DM
30the named commit will be listed. If the <commit> argument is missing it
31defaults to 'HEAD' (i.e. the tip of the current branch).
7fc9d69f 32
e5ac1217 33In the command's second form, a new branch named <branchname> will be created.
2eaf273d
SE
34It will start out with a head equal to the one given as <start-point>.
35If no <start-point> is given, the branch will be created with a head
36equal to that of the currently checked out branch.

38Note that this will create the new branch, but it will not switch the
39working tree to it; use "git checkout <newbranch>" to switch to the
40new branch.
41
572fc81d 42When a local branch is started off a remote branch, git sets up the
ba020ef5 43branch so that 'git-pull' will appropriately merge from
572fc81d
JS
44the remote branch. This behavior may be changed via the global
45`branch.autosetupmerge` configuration flag. That setting can be
46overridden by using the `--track` and `--no-track` options.

48With a '-m' or '-M' option, <oldbranch> will be renamed to <newbranch>.
49If <oldbranch> had a corresponding reflog, it is renamed to match
50<newbranch>, and a reflog entry is created to remember the branch
51renaming. If <newbranch> exists, -M must be used to force the rename
52to happen.
53
2eaf273d 54With a `-d` or `-D` option, `<branchname>` will be deleted. You may
3a4b3f26 55specify more than one branch for deletion. If the branch currently
1e72a40d
JH
56has a reflog then the reflog will also be deleted.
57
58Use -r together with -d to delete remote-tracking branches. Note, that it
59only makes sense to delete remote-tracking branches if they no longer exist
e5ac1217
DM
60in the remote repository or if 'git-fetch' was configured not to fetch
61them again. See also the 'prune' subcommand of linkgit:git-remote[1] for a
62way to clean up all obsolete remote-tracking branches.

79 Reset <branchname> to <startpoint> if <branchname> exists

e5ac1217 112 Display the full sha1s in the output listing rather than abbreviating them.
5e00f6fa 113
84d176ce 114--track::
e5ac1217 115 When creating a new branch, set up the configuration so that 'git-pull'
572fc81d
JS
116 will automatically retrieve data from the start point, which must be
117 a branch. Use this if you always pull from the same upstream branch
e5ac1217 118 into the new branch, and if you do not want to use "git pull
572fc81d
JS
119 <repository> <refspec>" explicitly. This behavior is the default
120 when the start point is a remote branch. Set the
121 branch.autosetupmerge configuration variable to `false` if you want
ba020ef5 122 'git-checkout' and 'git-branch' to always behave as if '--no-track' were
572fc81d
JS
123 given. Set it to `always` if you want this behavior when the
124 start-point is either a local or remote branch.

129--contains <commit>::
130 Only list branches which contain the specified commit.
131

136 Do not list branches which are fully contained by HEAD.
137
52a22d1e 138<branchname>::
d4072c97 139 The name of the branch to create or delete.
2b1f4247 140 The new branch name must pass all checks defined by
5162e697 141 linkgit:git-check-ref-format[1]. Some of these checks
2b1f4247 142 may restrict the characters allowed in a branch name.

145 The new branch will be created with a HEAD equal to this. It may
146 be given as a branch name, a commit-id, or a tag. If this option
147 is omitted, the current branch is assumed.
148
c976d415
LH
149<oldbranch>::
150 The name of an existing branch to rename.
151
152<newbranch>::
153 The new name for an existing branch. The same restrictions as for
e5ac1217 154 <branchname> apply.

157Examples
2eaf273d 158--------
1e2ccd3a 159
e5ac1217 160Start development from a known tag::
1e2ccd3a
JH
161+
162------------
163$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6
164$ cd my2.6
2eaf273d 165$ git branch my2.6.14 v2.6.14 <1>
1e2ccd3a 166$ git checkout my2.6.14
1e2ccd3a 167------------
2eaf273d
SE
168+
169<1> This step and the next one could be combined into a single step with
170"checkout -b my2.6.14 v2.6.14".
1e2ccd3a 171
e5ac1217 172Delete an unneeded branch::
1e2ccd3a
JH
173+
174------------
175$ git clone git://git.kernel.org/.../git.git my.git
176$ cd my.git
33b1f3d5
FM
177$ git branch -d -r origin/todo origin/html origin/man <1>
178$ git branch -D test <2>
2eaf273d
SE
179------------
180+
e5ac1217
DM
181<1> Delete the remote-tracking branches "todo", "html" and "man". The next
182'fetch' or 'pull' will create them again unless you configure them not to.
183See linkgit:git-fetch[1].
184<2> Delete the "test" branch even if the "master" branch (or whichever branch
185is currently checked out) does not have all commits from the test branch.

188Notes
189-----
190
e5ac1217 191If you are creating a branch that you want to checkout immediately, it is
2eaf273d
SE
192easier to use the git checkout command with its `-b` option to create
193a branch and check it out with a single command.
194
e5ac1217 195The options `--contains`, `--merged` and `--no-merged` serve three related
9a7ea2b1
LH
196but different purposes:
197
198- `--contains <commit>` is used to find all branches which will need
199 special attention if <commit> were to be rebased or amended, since those
200 branches contain the specified <commit>.
201
202- `--merged` is used to find all branches which can be safely deleted,
203 since those branches are fully contained by HEAD.
204
205- `--no-merged` is used to find branches which are candidates for merging
206 into HEAD, since those branches are not fully contained by HEAD.
