1. [Users and Groups](https://www.ask-codey.com/lessons/bash-users-and-groups) (Journeyman): Every person and many programs on a Linux computer have a user account with a number and a list of groups: whoami, id and groups show yours, /etc/passwd lists every account, adduser and usermod -aG add a person and a group, and a server runs each program as a user of its own.
