Learn the real terminal, free and risk-free
Step-by-step courses with the integrated terminal: every exercise grades itself while you practice on a virtual system. Nothing to install, no sign-up.

Basic Linux Course
From zero to console fluency: 24 lessons that grade themselves while you practice, with the built-in terminal.
Intermediate Linux Course

Windows course (CMD and PowerShell)

How it works
- 1.Pick a lesson from the syllabus and read the briefing.
- 2.The integrated terminal walks you through each step with the simulator's real commands.
- 3.Each step is validated against the virtual disk: get it right and you move on, with cascading hints if you don't.
- 4.Your progress is stored in your browser. Finish all 24 lessons and you know base bash.
What it is and where it ends
- Lessons grade against a simulated system in your browser: it never touches your computer or network.
- Progress lives in your browser (localStorage); no accounts, no servers.
- It covers LPIC-1 base practice (103.x and 104.x), without replacing the official certification.
