Very straight forward, create a user, a home folder, assign permissions to it, you’re done ! This create a simple user, with no particular rights.

useradd johnyluky
passwd johnyluky
mkdir /home/johnyluky
chown johnyluky:users /home/johnyluky

Anyone wants to pitch in to add a bit more to this ? Add more rights to the users for specific function ?
Leave a comment and I’ll gladly add it !
