exit_0 is a terminal-based Linux lab environment built around real system administration tasks. The labs are designed to develop operational habits: inspecting system state, applying safe changes, verifying results, and diagnosing failures.

These write-ups form the operational backbone of the labs. Each one documents the objective, the commands involved, the expected system state, and the common breakpoints that surface in production environments. The emphasis is on repeatable workflows, clear verification, and stable outcomes rather than one-off command success.

exit_0 is intended for Linux system administrators, and IT professionals transitioning into Linux-focused roles.
