UNIX Desktop Questions & Answers

I just created a group. How do i make the groups read only to a specific file systems.(home directory).

You would set the group as the 'group' of the directory and set the permissions

ls -l /export/mydir

drwxrwxr-x 2 root mygrp 4096 Sep 22 2000 mydir

chmod 745 mydir
(This would change it to read only for the group, not for the world)

ls -l /export/mydir
drwxr--r-x 2 root mygrp 4096 Sep 22 2000 mydir

You may have to change the default umask (check the man page on this and all commands before doing them)

Do I need to be root to do this. I'm assuming that I do. But we know what happens when you assume

If you are the owner of the directory then no, you don't need to be root. To change the umask for all users, yes.

Read the man pages on the commands.
