All levels Nothing to install Nothing to break

The Terminal Playground

A safe, simulated Linux shell running entirely in your browser. Practise the commands every IT job expects — ping, nslookup, ls, traceroute — with guided missions tied to trail posts. Type help to see what it speaks, or pick a mission and follow the objective.

Trail note

Everything here is simulated — no real network traffic is sent and no real files exist, so experiment freely. When a command clicks and you want the full story behind it, the missions link to the trail posts that explain what's really happening under the hood.
