A beginner Linux challenge worth 3 points. Solve it hands-on in a real Linux environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: Server migration day. You need to archive the project, then recover files from an old backup.

Your tasks:

1. Create a compressed archive of /tmp/project/ → save as /tmp/project_backup.tar.gz
2. Extract /tmp/mystery.tar.gz into /tmp/extracted/ (create the dir first)
3. Find the file named secret.txt inside /tmp/extracted/ and write its contents to /tmp/secret_answer.txt

Commands to learn: tar -czf, tar -xzf, tar -tzf (list contents), mkdir

Run check when done.
