The "physlock -m" command is used to lock the physical console of a Linux system.
When this command is executed, it will block any input from the keyboard and the mouse, effectively preventing any user from accessing or interacting with the system at the physical console. This is commonly used as a security measure to prevent unauthorized access when the system is unattended or left idle.
The "-m" option stands for "mouse" and is used to include mouse input in the lock, meaning that both the keyboard and mouse will be disabled when the command is executed. If the "-m" option is not specified, only the keyboard input will be blocked.
To unlock the console and regain access, the user typically needs to input a password or specific key combination, depending on the configuration of the physlock tool.
