Why do I need it?
The terminal looks plain. Just a blinking cursor. But behind that simplicity is a tool that developers swear by — because it’s fast, efficient, and powerful.
From navigating files to managing code and deploying servers, the terminal becomes your command center. It feels like magic when things start clicking — what used to be a chore becomes effortless.
And the best part? You don’t just use it — you start to love it. The terminal transforms how you work, and once you’re comfortable, you won’t look back.
How does it work?
This platform was built from the ground up over three years, designed solely to teach you the terminal. While other platforms cover a bit of everything, this one is focused entirely on mastering the command line.
Interactive exercises run directly in your browser’s terminal. The system tracks your actions and offers contextual guidance to support your learning.
The core curriculum teaches critical terminal skills efficiently. Additional content includes command tutorials, technical articles, and reference cheatsheets.

I'm a total beginner when it comes to command line and I was looking for a good place to start. learncmd.io is just what I needed! The tutorials are very well-made, and interactive which makes learning the basics of Linux so much easier, especially if you have minimal knowledge about operating systems. Highly recommended for all beginners!
