A sandboxed shell surface for practising Linux commands and directory navigation, with a sample filesystem and no machine to break.

Browser Linux Environment
Frontend preview — no upload or external service.
Session preview
$ ls -la /home/learner → drwxr-xr-x notes/ projects/ .bashrc — a sample tree you can move around in without touching a real machine.
How the Browser Linux Environment works
- Pick the lesson that matches what you are learning right now.
- Type commands against the sample filesystem and read the output as you would in a real shell.
- Break things freely — the sandbox resets, and nothing on your own machine is reachable.
FAQ
Is this a real Linux kernel?
No. It is a teaching surface for command syntax and navigation, not a virtual machine. Use it to build muscle memory, then move to a real shell or container for actual work.
Which commands should a beginner learn first?
pwd, ls, cd and cat cover most navigation. Add grep and less next, because reading files and searching them is the bulk of day-to-day terminal use.
Can it damage my computer?
No. It has no access to your filesystem, your network, or anything outside the page.

Browser Linux Environment is a practice keyboard for shell syntax — deliberately not a virtual machine, and honest about it.
