I have created the following git hook to update my web application when new changes are pushed to the repository
#!/bin/sh
#Update the server version to HEAD
echo "Updating webapp..."
unset $(git rev-parse --local-env-vars)
(cd /var/www/webapp && git pull -q)
However, if I add new files they get the wrong permissions. They are only readable by the owner and not by the group or by other users. But I need them to be readable by everyone. Locally they have the right permission bits. And even when I run the hook manually from the shell, it works correctly. It only doesn't work when the script is called as a hook.
Any ideas how to fix that?
PS: I am using git 1.7
