==================

NAME
----
git-show-branch - Show branches and their commits

SYNOPSIS
--------
[verse]
'git-show-branch' [--all] [--heads] [--tags] [--topo-order] [--current]
		[--more=<n> | --list | --independent | --merge-base]
		[--no-name | --sha1-name] [<rev> | <glob>]...

DESCRIPTION
-----------

Shows the commit ancestry graph starting from the commits named
with <rev>s or <globs>s (or all refs under $GIT_DIR/refs/heads
and/or $GIT_DIR/refs/tags) semi-visually.

It cannot show more than 29 branches and commits at a time.

It uses `showbranch.default` multi-valued configuration items if
no <rev> nor <glob> is given on the command line.


OPTIONS
-------
<rev>::
	Arbitrary extended SHA1 expression (see `git-rev-parse`)
	that typically names a branch HEAD or a tag.

<glob>::
	A glob pattern that matches branch or tag names under
	$GIT_DIR/refs.  For example, if you have many topic
	branches under $GIT_DIR/refs/heads/topic, giving
	`topic/*` would show all of them.

--all --heads --tags::
	Show all refs under $GIT_DIR/refs, $GIT_DIR/refs/heads,
	and $GIT_DIR/refs/tags, respectively.

--current::
	With this option, the command includes the current
	branch to the list of revs to be shown when it is not
	given on the command line.

--topo-order::
        By default, the branches and their commits are shown in
        reverse chronological order.  This option makes them
        appear in topological order (i.e., descendant commits
        are shown before their parents).

--more=<n>::
	Usually the command stops output upon showing the commit
	that is the common ancestor of all the branches.  This
	flag tells the command to go <n> more common commits
	beyond that.  When <n> is negative, display only the
	<reference>s given, without showing the commit ancestry
	tree.

--list::
	Synonym to `--more=-1`

--merge-base::
	Instead of showing the commit list, just act like the
	'git-merge-base -a' command, except that it can accept
	more than two heads.

--independent::
	Among the <reference>s given, display only the ones that
	cannot be reached from any other <reference>.

--no-name::
	Do not show naming strings for each commit.

--sha1-name::
	Instead of naming the commits using the path to reach
	them from heads (e.g. "master~2" to mean the grandparent
	of "master"), name them with the unique prefix of their
	object names.

Note that --more, --list, --independent and --merge-base options
are mutually exclusive.


OUTPUT
------
Given N <references>, the first N lines are the one-line
description from their commit message.  The branch head that is
pointed at by $GIT_DIR/HEAD is prefixed with an asterisk `*`
character while other heads are prefixed with a `!` character.

Following these N lines, one-line log for each commit is
displayed, indented N places.  If a commit is on the I-th
branch, the I-th indentation character shows a `+` sign;
otherwise it shows a space.  Merge commits are denoted by
a `-` sign.  Each commit shows a short name that
can be used as an extended SHA1 to name that commit.

The following example shows three branches, "master", "fixes"
and "mhf":

------------------------------------------------
$ git show-branch master fixes mhf
* [master] Add 'git show-branch'.
 ! [fixes] Introduce "reset type" flag to "git reset"
  ! [mhf] Allow "+remote:local" refspec to cause --force when fetching.
---
  + [mhf] Allow "+remote:local" refspec to cause --force when fetching.
  + [mhf~1] Use git-octopus when pulling more than one heads.
 +  [fixes] Introduce "reset type" flag to "git reset"
  + [mhf~2] "git fetch --force".
  + [mhf~3] Use .git/remote/origin, not .git/branches/origin.
  + [mhf~4] Make "git pull" and "git fetch" default to origin
  + [mhf~5] Infamous 'octopus merge'
  + [mhf~6] Retire git-parse-remote.
  + [mhf~7] Multi-head fetch.
  + [mhf~8] Start adding the $GIT_DIR/remotes/ support.
*++ [master] Add 'git show-branch'.
------------------------------------------------

These three branches all forked from a common commit, [master],
whose commit message is "Add 'git show-branch'.  "fixes" branch
adds one commit 'Introduce "reset type"'.  "mhf" branch has many
other commits.  The current branch is "master".


EXAMPLE
-------

If you keep your primary branches immediately under
`$GIT_DIR/refs/heads`, and topic branches in subdirectories of
it, having the following in the configuration file may help:

------------
[showbranch]
	default = --topo-order
	default = heads/*

------------

With this, `git show-branch` without extra parameters would show
only the primary branches.  In addition, if you happen to be on
your topic branch, it is shown as well.
