Redhat Linux 5.10 (Tikanga)
I'm trying to add an existing user to a second group. The user is already part of the primary group called "prim" and the secondary group I want to add him to is "sec". I've tried these:
sudo usermod --append sec chuck # Got the syntax screen for usermod
sudo usermod -G prim -append sec chuck # Got the syntax screen again.
The man page for usermod
says --append GROUP
requires the -G
, which I did. So, how do I add this user to a second group?
