I kind of figured that out, but I'm really looking for documentation on security. I can find man pages on commands, like adduser and addgroup, but I haven't found any pages on file security. I would guess the command name would be someone's cats name (many command names in Linux sure don't make much sense<G>).
With groups, I can see how I could setup a group of users that have access to each others files, but not how to have one user have full r/w access to a set of users files, without those users having more access then just their own files.
As has been said, for a general solution to this, you would want ACLs.
You could hack around it by making the users' directories all owned by, let's say, group "kahuna", and setting the group sticky bit on the directories so that new files created are owned by group "kahuna":
#cd /home #ls alice bob carol #chgrp kahuna alice bob carol #chmod g+s alice bob carol
Let's say "frank" is the user who should have write access to these files: you just put "frank" in group "kahuna" (vigr is usually the command to edit /etc/groups atomically), and, just as important, you make sure that alice, bob, and carol are *not* in group "kahuna."
Does anyone know of a good Unix file permissions tutorial? I soaked all this up in the early 90s when I was learning Unix for the first time, but I don't know where you go to absorb it for the first time.
