Tutorial on defining users and groups – https://www.techrepublic.com/article/how-to-create-users-and-groups-in-linux-from-the-command-line/
- sudo useradd <username>– create user without home directory, and no login capability
- sudo useradd -m <username>– create user with home directory matching username.
- Set up password:
- Create user and then sudo passwd <username>
- Or… set password at the same time sudo useradd -m <username> -p PASSWORD
Create Group: sudo groupadd <group>
Add user to group: sudo usermod -a -G <group> <username>
List of group memberships in /etc/group
And then, when editing your own group membership, don’t forget to logout and back in so they’ll take effect (not that I’d ever forget such a thing….). https://stackoverflow.com/a/5054930
