`branch.autoSetupMerge` configuration flag. That setting can be
overridden by using the `--track` and `--no-track` options, and
changed later using `git branch --set-upstream-to`.

With a `-m` or `-M` option, _<old-branch>_ will be renamed to _<new-branch>_.
If _<old-branch>_ had a corresponding reflog, it is renamed to match
_<new-branch>_, and a reflog entry is created to remember the branch
renaming. If _<new-branch>_ exists, `-M` must be used to force the rename
to happen.

The `-c` and `-C` options have the exact same semantics as `-m` and
`-M`, except instead of the branch being renamed, it will be copied to a
new name, along with its config and reflog.

With a `-d` or `-D` option, _<branch-name>_ 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 the remote repository or if `git fetch` was configured not to fetch
them again. See also the `prune` subcommand of linkgit:git-remote[1] for a
way to clean up all obsolete remote-tracking branches.


OPTIONS
-------
`-d`::
`--delete`::
	Delete a branch. The branch must be fully merged in its
	upstream branch, or in `HEAD` if no upstream was set with
	`--track` or `--set-upstream-to`.

`-D`::
	Shortcut for `--delete --force`.

`--create-reflog`::
	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 `<branch-name>@{yesterday}`.
	Note that in non-bare repositories, reflogs are usually
	enabled by default by the `core.logAllRefUpdates` config option.
	The negated form `--no-create-reflog` only overrides an earlier
	`--create-reflog`, but currently does not negate the setting of
	`core.logAllRefUpdates`.

`-f`::
`--force`::
	Reset _<branch-name>_ to _<start-point>_, even if _<branch-name>_ exists
	already. Without `-f`, `git branch` refuses to change an existing branch.
	In combination with `-d` (or `--delete`), allow deleting the
	branch irrespective of its merged status, or whether it even
	points to a valid commit. In combination with
	`-m` (or `--move`), allow renaming the branch even if the new
	branch name already exists, the same applies for `-c` (or `--copy`).
+
Note that `git branch -f <branch-name> [<start-point>]`, even with `-f`,
refuses to change an existing branch _<branch-name>_ that is checked out
in another worktree linked to the same repository.

`-m`::
`--move`::
	Move/rename a branch, together with its config and reflog.

`-M`::
	Shortcut for `--move --force`.

`-c`::
`--copy`::
	Copy a branch, together with its config and reflog.

`-C`::
	Shortcut for `--copy --force`.

`--color[=<when>]`::
	Color branches to highlight current, local, and
	remote-tracking branches.
	The value must be `always` (the default), `never`, or `auto`.

`--no-color`::
	Turn off branch colors, even when the configuration file gives the
	default to color output.
	Same as `--color=never`.

`-i`::
`--ignore-case`::
	Sorting and filtering branches are case insensitive.

`--omit-empty`::
	Do not print a newline after formatted refs where the format expands
	to the empty string.

`--column[=<options>]`::
`--no-column`::
	Display branch listing in columns. See configuration variable
	`column.branch` for option syntax. `--column` and `--no-column`
	without options are equivalent to `always` and `never` respectively.
+
This option is only applicable in non-verbose mode.

`--sort=<key>`::
	Sort based on _<key>_. Prefix `-` to sort in descending
	order of the value. You may use the `--sort=<key>` option
	multiple times, in which case the last key becomes the primary
	key. The keys supported are the same as those in linkgit:git-for-each-ref[1].
	Sort order defaults to the value configured for the
	`branch.sort` variable if it exists, or to sorting based on the
