Welcome to Learn Linux

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.

Learning Goals

Understand the difference between a shell and a terminal
Learn how to navigate and use the file system using the command line
Learn how to install software using the command line
Understand how to manage your PATH and environment variables
Learn how to manage permissions and execute programs

This 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.

Assignment

The echo command prints text back out to you. It's the "hello world" of the command line.

The shell is where you run commands. Type a command, press Enter, and the shell runs it.

In the shell on the right, type the following command:
```
echo "I use Linux btw"
```
Press Enter to run it.

Submit the shell checks.
