git diff during pre-commit hook results in Not a git repository

Question

I\'m trying to build a pre-commit script in git. In that script I plan on running tasks if a certain folder has changed. To test, in my script I have

git d         


        

Answer 1

Even though GIT_DIR is set, I would still try a:

git --git-dir=/full/path/to/repo/.git --work-tree=/full/path/to/rpeo diff --cached |grep -q "^my/folder" 

That way, you are sure the hook is executed where it is supposed to.
