01:12:38 haven't checked, but doesn't -g change the main group for the user? check their entry in /etc/passwd and see if it happened there. 01:13:43 ah, yep: 01:13:47 -g group 01:13:47 Specify an existing group's integer ID or character-string name. It 01:13:47 redefines the user's primary group membership. 01:14:05 Use -G for additional groups. 01:14:12 (see 'man usermod' for details.) 01:18:23 Nope. Not in either, contrary to what the manpage for usermod shows. Where is 'groups' getting its info from? 06:34:25 jayjwa: Assuming you have "group: files" in /etc/nssswitch.conf it comes from /etc/group 07:42:20 hi all 08:19:15 jayjwa: the new group will not affect extisting logins of the user, only new logins. (login(1) is what's setting the groups; an "su - $USER" should do, too.) 13:27:14 Something's off here. https://termbin.com/dg79 Ignore the escape sequences; they were originally color output. 16:55:17 When a user's primary is that group, he doesn't have to be listed after the group in /etc/groups. It is not necessary for the user to have the primary group also be the secondary group. That is the answer to my question. Sorry for the noise.
