When navigating the internet you find aliases, configs, .dot files you might like to try.

Before you do try to know as much as possible about the code.

We are going to study this line of code from Nick Petrov.

Most of the commands have either a manual or a help function.

These are the most common ones.

We check the manual for pacman  with man pacman and go read about all the switches.

Definitely read about pacman in the arch wiki.

This means you are cleaned up.
