Note to self...

[johnridley]

it's "sudo usermod -aG (groups) user"

Do not forget the "a". Otherwise this group list will REPLACE the old groups.

You don't want to get kicked out of the sudo group, really. But if you do, boot to a live CD, then mkdir /ubuntu, mount (linux root) /ubuntu, chroot /ubuntu, then you can usermod -aG sudo user.

Ahh, Linux. Needing special tools to edit /etc/group, and forgetting that the "can become root" group is called "wheel".

I could rename "admin" to "wheel" but it's just words. Blame Stallman. Everyone else does.

I have hand edited group before, the commands are just easier. The one they warn you about is hand editing sudoers.
