From 44e1e4d67d5148c245db362cc48c3cc6c2ec82ca Mon Sep 17 00:00:00 2001 From: Nazri Ramliy Date: Mon, 9 Sep 2013 21:47:43 +0800 Subject: git: run in a directory given with -C option This is similar in spirit to "make -C dir ..." and "tar -C dir ...". It takes more keypresses to invoke git command in a different directory without leaving the current directory: 1. (cd ~/foo && git status) git --git-dir=~/foo/.git --work-dir=~/foo status GIT_DIR=~/foo/.git GIT_WORK_TREE=~/foo git status 2. (cd ../..; git grep foo) 3. for d in d1 d2 d3; do (cd $d && git svn rebase); done The methods shown above are acceptable for scripting but are too cumbersome for quick command line invocations. With this new option, the above can be done with fewer keystrokes: 1. git -C ~/foo status 2. git -C ../.. grep foo 3. for d in d1 d2 d3; do git -C $d svn rebase; done A new test script is added to verify the behavior of this option with other path-related options like --git-dir and --work-tree.
