Introduction

A brief overview of the Learn the Command Line course.

What is the Command Line?

The command line is a text interface for the computer’s operating system. You can use it to traverse and edit your computer’s filesystem. Through the command line, you can create new files, edit the contents of those files, delete files, and more!

We access the command line through something called Bash. We’ll go into what that means and how to set it up on your personal device later in the course, but feel free to look ahead now.

What will you learn?

This course will take you through the various functionalities of how to use the command line, starting with navigation, and ending with configuring the environment. At any point, you can access the cheatsheet of commands for this course here.
