I tried to simplify all the keystrokes / shortcuts and common terminal commands that I use daily myself... I hope it helps anyone, spent too much time writing this.

macOS - Terminal.md

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.
