The groupmems command allows a user to administer his/her own group membership list without the requirement of superuser privileges. The groupmems utility is for systems that configure its users to be in their own name sake primary group (i.e., guest / guest).

Only the superuser, as administrator, can use groupmems to alter the memberships of other groups.

SETUP¶

The groupmems executable should be in mode 2770 as user root and in group groups. The system administrator can add users to group groups to allow or disallow them using the groupmems utility to manage their own group membership list.

	$ groupadd -r groups
	$ chmod 2770 groupmems
	$ chown root.groups groupmems
