Introduction

Version control is an amazing tool. It’s overwhelming now, but you’re going to be using this extensively both in school and when you get into industry.

We’ll keep using version control throughout this course, but, for now, we’re going to move on.

We’re going to be spending some quality time with our shells 🐚. That plain-text interface seems to be both intimidating and primitive all at the same time. Yes, shells can be intimidating, but we can do pretty powerful things with shells that might otherwise seem magical to someone who’s never written a program before.

“But I can just write a program to do that!” I’ll hear you thinking (through both space, and time). Yeah, you can write a program to do the same things we’re going to see in some command line tools, but why would you write a program that already exists?
