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.
