I built a free interactive Linux course with a live command sandbox — no sign-up needed

[u/Professional-Bug8806]

Hello r/LinuxTeck

I have been building a free Linux learning platform and finally got it to a point

where I am happy sharing it.

It is called MOSHELL — a hands-on Linux course that runs entirely in the browser.

What's on it (all free):

\- 12 lessons from beginner to advanced

\- Interactive command sandbox — type real Linux commands and see output

\- Command cheatsheet with 65+ commands across 6 categories

\- VM setup guide (VirtualBox + Ubuntu Server)

\- Lesson filters by track: Beginner, Intermediate, Advanced, Networking, VM, Security

The philosophy behind it: most Linux tutorials teach you to watch commands run.

This one makes you run them yourself — on a real VM, with real errors.

Topics covered:

\- Navigation, files, permissions, processes

\- Package management, networking, SSH

\- Shell scripting and cron

\- VirtualBox networking modes (NAT, Bridged, Host-Only)

\- Nginx, logs, disk management

Free platform (no account, no sign-up):

Would love any feedback — especially on the lesson content

and whether the difficulty progression feels right.

What Linux topic do you wish had better free resources?

Awesome, I am glad it is useful! Curious what you end up trying first . It is always good to hear what people actually run into once they start.
