Adding an existing user to a group in Linux

Question

Set up a second user on my Ubuntu box and need them in the docker group. I don't want to remove them from their other groups by accident. What's the right command?

sudo usermod -aG groupname username Don't forget the -a. Without it, -G replaces all the user's other groups with just that one, which is how people lock themselves out of sudo. The change only applies after the user logs out and back in.
