Delete only if empty
sudo delgroup --only-if-empty [groupname]
说明
delgroup removes a group from the system or removes a user from a group. It's the Debian/Ubuntu counterpart to groupdel with additional safety features. When called with just a group name, it deletes the group. With both user and group names, it removes the user from that group without deleting the group.
