As such, it's "reasonably stable", but at 16the same time also reasonably unique, ie two patches that have the same "patch 17ID" are almost guaranteed to be the same thing. 18 19IOW, you can use this thing to look for likely duplicate commits. 20 21OPTIONS 22------- 23<patch>:: 24 The diff to create the ID of. 25 26Author 27------ 28Written by Linus Torvalds <torvalds@osdl.org> 29 30Documentation 31-------------- 32Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 33 34GIT 35--- 36Part of the link:git.html[git] suite 37
