Question 40
Using Red Hat Enterprise Linux 9, create a directory named 'friends' within the /tmp directory. Then, change the directory's ownership to the 'friends' group. Configure the directory permissions so that only members of the 'friends' group and the root user can access this directory.
Show model answer
First, create the directory with mkdir /tmp/friends. Then, to change the group ownership, use chgrp friends /tmp/friends. Finally, set the directory permissions so only the group members and root can access it using chmod 770 /tmp/friends. This assigns full permissions (read, write, execute) to the owner and group, and no permissions to others. The '770' permission ensures that only users in the 'friends' group and the root user can access the directory.
