Don’t be afraid of Terminal on any OS, let me simplify things for you! I’ve been using Terminal a lot lately, yet I remember the time when I was entirely afraid of even typing anything in it...

Whenever I needed something on my Mac, that required Terminal commands, I had a tough time figuring what does it mean, how does it work; especially when it's a very long one. Well, it was worth it, not just copy/pasting the command, seeing it works and continuing with my day.
