Terminal Playground

No. This page simulates a shell entirely in your browser. It looks and behaves like a terminal for a small set of commands, but there is no real Unix shell, container, VM, or remote machine behind it. Unsupported commands intentionally return command not found instead of touching any real system.

The playground is intentionally small and focused on common file-navigation and inspection workflows. It supports commands like ls, cd, cat, head, tail, du, and rm over the seeded virtual filesystem, plus a working jq filter for the example JSON files. It also includes conveniences such as command history and Tab completion.

No. The file tree is virtual and lives only inside the page state in your browser tab. Even rm only removes files from that simulated environment, and a refresh restores the original seeded files. Nothing can read from or write to your actual disks through this tool.

Because the terminal UI is simulated, but the jq filtering itself is real browser-side execution. This page reuses the same in-browser jq engine as the dedicated JQ Playground, so filters run against the bundled example JSON files locally without needing a backend shell session.

No. Commands, paths, and jq filters stay in your browser. The goal of the tool is to let you practice basic shell-style workflows and experiment with jq safely, without sending your input to a remote OS or filesystem.
