Option `-r` causes the remote-tracking +branches to be listed, and option `-a` shows both. + +With `--contains`, shows only the branches that contains the named commit +(in other words, the branches whose tip commits are descendant of the +named commit). With `--merged`, only branches merged into the named +commit (i.e. the branches whose tip commits are reachable from the named +commit) will be listed. With `--no-merged` only branches not merged into +the named commit will be listed. Missing <commit> argument defaults to +'HEAD' (i.e. the tip of the current branch). + +In its second form, a new branch named <branchname> will be created. +It will start out with a head equal to the one given as <start-point>. +If no <start-point> is given, the branch will be created with a head +equal to that of the currently checked out branch. + +Note that this will create the new branch, but it will not switch the +working tree to it; use "git checkout <newbranch>" to switch to the +new branch. + +When a local branch is started off a remote branch, git sets up the +branch so that 'git-pull' will appropriately merge from +the remote branch. This behavior may be changed via the global +`branch.autosetupmerge` configuration flag. That setting can be +overridden by using the `--track` and `--no-track` options. + +With a '-m' or '-M' option, <oldbranch> will be renamed to <newbranch>. +If <oldbranch> had a corresponding reflog, it is renamed to match +<newbranch>, and a reflog entry is created to remember the branch +renaming. If <newbranch> exists, -M must be used to force the rename +to happen. + +With a `-d` or `-D` option, `<branchname>` will be deleted. You may +specify more than one branch for deletion. If the branch currently +has a reflog then the reflog will also be deleted. + +Use -r together with -d to delete remote-tracking branches. Note, that it +only makes sense to delete remote-tracking branches if they no longer exist +in remote repository or if 'git-fetch' was configured not to fetch +them again. See also 'prune' subcommand of linkgit:git-remote[1] for way to +clean up all obsolete remote-tracking branches. + + +OPTIONS +------- +-d:: + Delete a branch. The branch must be fully merged in HEAD. + +-D:: + Delete a branch irrespective of its merged status. + +-l:: + Create the branch's reflog. This activates recording of + all changes made to the branch ref, enabling use of date + based sha1 expressions such as "<branchname>@\{yesterday}". + +-f:: + Force the creation of a new branch even if it means deleting + a branch that already exists with the same name. + +-m:: + Move/rename a branch and the corresponding reflog. + +-M:: + Move/rename a branch even if the new branchname already exists. + +--color:: + Color branches to highlight current, local, and remote branches. + +--no-color:: + Turn off branch colors, even when the configuration file gives the + default to color output. + +-r:: + List or delete (if used with -d) the remote-tracking branches. + +-a:: + List both remote-tracking branches and local branches. + +-v:: +--verbose:: + Show sha1 and commit subject line for each head. + +--abbrev=<length>:: + Alter minimum display length for sha1 in output listing, + default value is 7. + +--no-abbrev:: + Display the full sha1s in output listing rather than abbreviating them. + +--track:: + When creating a new branch, set up configuration so that 'git-pull' + will automatically retrieve data from the start point, which must be + a branch. Use this if you always pull from the same upstream branch + into the new branch, and if you don't want to use "git pull + <repository> <refspec>" explicitly. This behavior is the default + when the start point is a remote branch. Set the + branch.autosetupmerge configuration variable to `false` if you want + 'git-checkout' and 'git-branch' to always behave as if '--no-track' were + given. Set it to `always` if you want this behavior when the + start-point is either a local or remote branch. + +--no-track:: + Ignore the branch.autosetupmerge configuration variable. + +--contains <commit>:: + Only list branches which contain the specified commit. + +--merged:: + Only list branches which are fully contained by HEAD. + +--no-merged:: + Do not list branches which are fully contained by HEAD. + +<branchname>:: + The name of the branch to create or delete. + The new branch name must pass all checks defined by + linkgit:git-check-ref-format[1]. Some of these checks + may restrict the characters allowed in a branch name. + +<start-point>:: + The new branch will be created with a HEAD equal to this. It may + be given as a branch name, a commit-id, or a tag. If this option + is omitted, the current branch is assumed. + +<oldbranch>:: + The name of an existing branch to rename. + +<newbranch>:: + The new name for an existing branch. The same restrictions as for + <branchname> applies. + + +Examples +-------- + +Start development off of a known tag:: ++ +------------ +$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6 +$ cd my2.6 +$ git branch my2.6.14 v2.6.14 <1> +$ git checkout my2.6.14 +------------ ++ +<1> This step and the next one could be combined into a single step with +"checkout -b my2.6.14 v2.6.14". + +Delete unneeded branch:: ++ +------------ +$ git clone git://git.kernel.org/.../git.git my.git +$ cd my.git +$ git branch -d -r origin/todo origin/html origin/man <1> +$ git branch -D test <2> +------------ ++ +<1> Delete remote-tracking branches "todo", "html", "man". Next 'fetch' or +'pull' will create them again unless you configure them not to. See +linkgit:git-fetch[1]. +<2> Delete "test" branch even if the "master" branch (or whichever branch is +currently checked out) does not have all commits from test branch. + + +Notes +----- + +If you are creating a branch that you want to immediately checkout, it's +easier to use the git checkout command with its `-b` option to create +a branch and check it out with a single command. + +The options `--contains`, `--merged` and `--no-merged` serves three related +but different purposes: + +- `--contains <commit>` is used to find all branches which will need + special attention if <commit> were to be rebased or amended, since those + branches contain the specified <commit>. + +- `--merged` is used to find all branches which can be safely deleted, + since those branches are fully contained by HEAD. + +- `--no-merged` is used to find branches which are candidates for merging + into HEAD, since those branches are not fully contained by HEAD. + +Author +------ +Written by Linus Torvalds <torvalds@osdl.org> and Junio C Hamano <gitster@pobox.com> + +Documentation +-------------- +Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. + +GIT +--- +Part of the linkgit:git[1] suite |
