Linux Playground

A real Linux machine running inside this browser tab — practice the course commands with nothing to install.

user@playground: ~

The machine boots entirely in your browser. The first start downloads ~30 MB and takes about a minute — after that it is cached and fast.

Best on a desktop browser — mobile keyboards are limited.

What works here

  • ✅ Files, folders, and navigation — ls, cd, mkdir, cp, mv, rm, find
  • ✅ Reading and editing — cat, less, nano, vim, grep
  • ✅ Text processing and pipes — sort, uniq, cut, awk, sed
  • ✅ Bash scripting — variables, loops, functions, chmod +x
  • ✅ Your files survive reloads — they are saved in your browser.

What needs a real VM

  • ❌ No internet inside the machine — apt install, ping, curl will not reach the network.
  • ❌ No services — systemctl, journalctl need a full system.
  • For those lessons, use the free local install (WSL on Windows, Multipass on macOS) — the course shows how in Getting started.
