Welcome to "Learn Linux"! Admittedly, the course name is a bit of a misnomer. It's called "Learn Linux" because "Linux" is what most students think of regarding the concepts in this course. A more accurate title might be "Learn to use shells and terminals in a Unix-like environment," but that's a mouthful.
PATH and environment variablesThis course will get you comfortable working on a command line, which is a skill that's going to be critical for the rest of your career as a programmer. So, instead of writing code in the browser, in this course you'll interact with a command line interface (CLI).
For the first part of the course, you don't even need to leave this page. We've embedded a real, working shell on the right. Later, once you're comfortable, you'll set everything up on your own machine.
The echo command prints text back out to you. It's the "hello world" of the command line.
echo "I use Linux btw"
Submit the shell checks.
