Multi-Level Group access


It has been awhile since I've need to do anything with permissions until now but I can't remember the trick to setting multi-level group permissions. I need to give one group R/W access, another R/O access while denying all access to everyone else. TIA.

I don't see how that helps. The R/O group does not exist with that directory. If I change the group to the R/O group then I have a problem with the R/W group.

Set GUID so the r/w group can share the files created. Then set all others to r/o. ( You also need execute to access the directory)

Code:

chmod -r 2775 /directory/in/question


2 - guid -- Files are created based on group
7 -rwx --> Owner
7 -rwx --> Group
5 -r-x --> Others


chown -R owner.group /directory/in/question
Now you should have a working directory for a group to share full access while all others can only read.

Thanks for the reply but that does no do what I need. Perhaps I was not clear enough in my original explanation. I do cannot give all others access. I need R/W for groupa, R/O for groupb and NO access for all others.

Go it. Unfortunately , I don't believe it is possible -- ---to have two seperate groups on a directory or a file.

Thanks. I believe I need ACLS to do that.
