GIT-CHERRY(1)							    Git Manual							     GIT-CHERRY(1)

NAME

       git-cherry - Find commits not merged upstream

SYNOPSIS

       git cherry [-v] [<upstream> [<head> [<limit>]]]

DESCRIPTION

       The changeset (or "diff") of each commit between the fork-point and <head> is compared against each commit between the fork-point and
       <upstream>. The commits are compared with their patch id, obtained from the git patch-id program.

       Every commit that doesn't exist in the <upstream> branch has its id (sha1) reported, prefixed by a symbol. The ones that have equivalent
       change already in the <upstream> branch are prefixed with a minus (-) sign, and those that only exist in the <head> branch are prefixed
       with a plus (+) symbol:

		      __*__*__*__*__> <upstream>
		     /
	   fork-point
		     \__+__+__-__+__+__-__+__> <head>

       If a <limit> has been given then the commits along the <head> branch up to and including <limit> are not reported:

		      __*__*__*__*__> <upstream>
		     /
	   fork-point
		     \__*__*__<limit>__-__+__> <head>

       Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally
       has been applied <upstream> under a different commit id. For example, this will happen if you're feeding patches <upstream> via email
       rather than pushing or pulling commits directly.

OPTIONS

       -v
	   Verbose.

       <upstream>
	   Upstream branch to compare against. Defaults to the first tracked remote branch, if available.

       <head>
	   Working branch; defaults to HEAD.

       <limit>
	   Do not report commits up to (and including) limit.
