From 5f94c730f31862c7f500173ee3a9d141c4730f0b Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 22 Dec 2005 22:35:38 -0800 Subject: [PATCH] rev-parse: --show-cdup When --show-prefix is useful, sometimes it is easier to cd up to the toplevel of the tree. This is equivalent to: git rev-parse --show-prefix | sed -e 's|[^/][^/]*|..|g' but we do not have to invoke sed for that.
