How do I change the permissions for a specific group that I have created?
Say for example I create four new users named Anna, David, Carl and Eva and I also create two different groups which I name technician and normaluser. Now when I have created these groups and users I move Anna to the technician group and David to normaluser.
But here is where I'm stuck, I dont know howto give the technician group 'rwx' or full permissions and give normaluser group 'rx' and the rest should just have 'x'.
I've tried with the command chgrp {-R} [group] [file|directory] .. But that kind of messed up my whole system, cause that command changes the group of all the stuff. Also I can't seem to find anything that works with chown {-R} [user]{:group} [file|directory].
