Because ann is the owner for Pset 7, she has authority to modify the
Pset’s user, group, and access permissions attributes.
Using the psrset -t... command, ann sets the group for Pset 7 to 102
(the group named prog). Another psrset -t... command sets access
permissions for Pset 7 to 770, which gives the owner (ann) and prog
group members access to execute, write, and read the Pset. All others
have no permissions to use or read Pset 7.
ann $ psrset -t 7 GRPID=102
ann $ psrset -t 7 PERM=770
ann $
Now ann assigns processor ID 8 to Pset 7, using the psrset -a...
command.
