说明
physlock locks all virtual consoles and prevents unauthorized access to the system. Unlike screen lockers that only protect graphical sessions, physlock secures all TTYs, preventing access through Ctrl+Alt+F1-F6 switching. Authentication is required from the current user or root to unlock. This makes it suitable for securing systems with physical access concerns, particularly servers or kiosks.
