getting "fatal: not a git repository: '.'" when using post-update hook to execute 'git pull' on another repo

Question

I'm new to git so I apologize (and please correct me) if I misuse terminology here, but I'll do my best.

I'm trying to set up a bare git repo (hub) and a development site working copy (prime) on a web server. I've tried to pattern it after this article. I want the development working copy to be updated whenever the hub repo is pushed to. I'm under the impression that the proper hook for this is post-update, which I have created like so:

#!/bin/sh whoami cd /path/to/working-copy/ RET=`git pull` echo $RET 

Update

When I push changes from my local repo to the bare hub I get the following output from the post-update script:

remote: sites remote: fatal: Not a git repository: '.' 

However if I SSH into the server as user 'sites' and execute this script manually it works great Any ideas as to what might be going wrong with this hook or script?

Answer 1

Here is the script that ultimately worked. I think the bit I was originally missing that prevented it from working remotely was the unset GIT_DIR

#!/bin/sh cd /path/to/working-copy/ || exit unset GIT_DIR git pull repo branch  exec git-update-server-info
