From 41bbf9d58575095234c64df979ee884334469758 Mon Sep 17 00:00:00 2001 From: Alex Riesen Date: Wed, 14 Mar 2007 01:17:04 +0100 Subject: Allow git-diff exit with codes similar to diff(1) This introduces a new command-line option: --exit-code. The diff programs will return 1 for differences, return 0 for equality, and something else for errors.
