DESCRIPTION
-----------
-With no arguments given a list of existing branches
-will be shown, the current branch will be highlighted with an asterisk.
-Option `-r` causes the remote-tracking branches to be listed,
-and option `-a` shows both.
-With `--contains <commit>`, shows only the branches that
-contains the named commit (in other words, the branches whose
-tip commits are descendant of the named commit).
-
-In its second form, a new branch named <branchname> will be created.

+With no arguments, existing branches are listed and the current branch will
+be highlighted with an asterisk. Option `-r` causes the remote-tracking
+branches to be listed, and option `-a` shows both.
+
+With `--contains`, shows only the branches that contain the named commit
+(in other words, the branches whose tip commits are descendants 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. If the <commit> argument is missing it
+defaults to 'HEAD' (i.e. the tip of the current branch).
+
+In the command's 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.
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 can setup the
-branch so that linkgit:git-pull[1] will appropriately merge from that
-remote branch. If this behavior is desired, it is possible to make it
-the default using the global `branch.autosetupmerge` configuration
-flag. Otherwise, it can be chosen per-branch using the `--track`
-and `--no-track` options.
+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
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 linkgit:git-fetch[1] 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
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.
+ Reset <branchname> to <startpoint> if <branchname> exists
+ already. Without `-f` 'git-branch' refuses to change an existing branch.
-m::
Move/rename a branch and the corresponding reflog.
-M::
- Move/rename a branch even if the new branchname already exists.
+ Move/rename a branch even if the new branch name already exists.
--color::
Color branches to highlight current, local, and remote branches.
-a::
List both remote-tracking branches and local branches.
--v, --verbose::
- Show sha1 and commit subject line for each head.
+-v::
+--verbose::
+ Show sha1 and commit subject line for each head, along with
+ relationship to upstream branch (if any). If given twice, print
+ the name of the upstream branch, as well.
--abbrev=<length>::
- Alter minimum display length for sha1 in output listing,
- default value is 7.
+ Alter the sha1's minimum display length in the output listing.
+ The default value is 7.
--no-abbrev::
- Display the full sha1s in output listing rather than abbreviating them.
+ Display the full sha1s in the output listing rather than abbreviating them.
+-t::
--track::
- Set up configuration so that git-pull will automatically
- retrieve data from the remote branch. Use this if you always
- pull from the same remote branch into the new branch, or if you
- don't want to use "git pull <repository> <refspec>" explicitly. Set the
- branch.autosetupmerge configuration variable to true if you
- want git-checkout and git-branch to always behave as if
- '--track' were given.
+ When creating a new branch, set up configuration to mark the
+ start-point branch as "upstream" from the new branch. This
+ configuration will tell git to show the relationship between the
+ two branches in `git status` and `git branch -v`. Furthermore,
+ it directs `git pull` without arguments to pull from the
+ upstream when the new branch is checked out.
++
+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::
- When a branch is created off a remote branch,
- set up configuration so that git-pull will not retrieve data
- from the remote branch, ignoring the branch.autosetupmerge
- configuration variable.
+ Do not set up "upstream" configuration, even if the
+ branch.autosetupmerge configuration variable is true.
+
+--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.
<newbranch>::
The new name for an existing branch. The same restrictions as for
- <branchname> applies.
+ <branchname> apply.

Notes
-----
-If you are creating a branch that you want to immediately checkout, it's
+If you are creating a branch that you want to checkout immediately, it is
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` serve 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.
