git post-receive hook not running

I had this problem. I had a typo in my script filename.

post-recieve instead of post-receive

In order for a Git hook to run, it needs to have permissions set to allow it to be executable. If a hook doesn't seem to be running, check the permissions, and make sure it's executable. If it isn't you can make all hooks executable like this:

chmod ug+x .git/hooks/*

...or if you want to make a single hook (eg. post-receive) executable:

chmod ug+x .git/hooks/post-receive
