A safe, simulated Linux shell — try out commands without needing a real machine. Nothing here can break anything; type help any time to see what's available, or reset to start fresh.
Your files here are saved in this browser, so they'll still be here next time you visit —
including from any lesson's embedded terminal. Type reset to wipe it and start over.
Want the real thing? Try the real Linux VM — a genuine kernel booting in your browser via WebAssembly (bigger download, no simulation).
