Hi,
I am using a VPS that is running redhat. So far I only have the root user and my own user that have all permissions. I am working with a web site developer and I want to create a new user account that can modify only a couple directories within the /var/www/html directory. I don't want them to have access to the database or other directories that have live websites where they could mess something up by accident. What is the best way of doing this?

thanks!
