If you are running linux, why not try it yourself and see what happens? You can use the adduser command. If you're not sure how to use adduser then just type

Code:

man adduser

in a terminal. This way you'll learn much more.

I won't say more than jdkaye, because I agree with him that you need to try it out for yourself. That's how I've done it and it was the best way. But am going to tell you that when you add a user to a group you need to log in again with that user in order for the changes to take effect. Otherwise, the user will only have the previous permissions on that file/directory (file /etc/group needs to be read on each login).

If you do web search for linux acl permissions, you would be able read the basic understanding of acls. Otherwise you have to do trial and error.
