I have file named
abc.txt and 3 groups (
I want to create a group name
CanView, which allow Teachers and Students to view the file
abc.txt. Can I add
You have to add each user to the group
CanView. You can't add a group to the group
But you could use ACL.
You can "add" them, but first you must read
man group and
man vigr. On my system, I have added myself to 14 groups. I am not giving you a
do this;do that style answer, because You must understand what you're doing before you do it, or learn how to recover from doing it wrong. I have tried both ways.
Once you've added them to the
group file, they must either
logout/login to apply the new group membership to the session, or use
newgrp CanView to spawn a single shell with the new group membership active..
