To simplify: A cheat sheet is a bunch of notes (In paper or digital) that helps in certain stuff, like, in this case, to use TERMINAL in Linux.

Example: whoami (when run as root) → Prints root. Otherwise, prints the username.

-add/-mod/del: Add, modify or delete. All goes with prefixes, as user.

Example: sudo Userdel  -m (Name) → Machine deletes the use named <Name>
