Welcome to Command Line 101: A crash course for MacOS and Linux users. If you’re brand new to the command line and want to learn it, or need to learn the command line for a new job, this course is for you. We’re going start at the very beginning and assume you have never used the command line before. We’ll start off by exploring a command line program, and then getting into some very simple commands. Over the course of this class we’ll start creating new files and folders in different parts of our computer. We’ll even start editing files directly on the command line! Why learn the command line?The command line seems OLD, and it is old, but it’s also powerful and extremely common still. People use the command line to execute Python scripts, maintain servers (like websites), compress images, run Node. js or other frontend tooling for website development, and much much more. The truth is: behind every program that has a graphical user interface (GUI) is some raw program that takes raw commands. If you don’t need to worry about the graphical user interface, your computer can run more efficiently. In fact, I’ve been using the command line for a number of years to do all sorts of things from transcoding videos (like the videos you see on this website) to losslessly compressing images to running entire fleets of servers for large scale websites. Requirements: MacOS or LinuxInternet to stream these videos
