Check out http://stackoverflow.com/questions/2432026/gitosis-admin-git-push-failed-exec-hooks-post-update (with its comment), and see if you need to set `GIT_DIR` environment variable. — VonC, Jan 31 '12 at 09:45
I believe in your hook script, just to make sure Git knows where to look when you are making your git commands like `git status`: the current directory isn't the only thing that matter. — VonC, Jan 31 '12 at 14:30
after cd ../ echo `basename $PWD` he is in _production, this is the git repo... — Alexander_F, Jan 31 '12 at 14:40
I would still recommend you try to set `GIT_DIR` to that `.git` directory full path (and `GIT_WORK_TREE` to the parent directory), to be extra sure. Test it and see of the errors persists. — VonC, Jan 31 '12 at 14:43

The problem here is that in a post-update hook in a non-bare repository, GIT_DIR is set to . and your current directory is the .git directory. For such details for each different git hook, see this underrated blog post ;)

That means that if you do cd .. then GIT_DIR will still be . but your current directory will no longer be the .git directory. Try beginning your hook script with:

export GIT_DIR=/whereever/production/.git
export GIT_WORK_TREE=/whereever/production/

... to be safe - the rules about how GIT_DIR and GIT_WORK_TREE interact are fiddly.
