The command "xtrlock" is used in Unix-like systems to lock the X display until the user's password is entered.
When executed, "xtrlock" starts a screen lock utility that prevents any input on the X display, such as mouse or keyboard events, from being processed. This prevents unauthorized access to the system while the user is momentarily away or unable to supervise the display.
To unlock the X display, the user needs to enter their password to regain control. Once the correct password is entered, the X display is unlocked, and the system returns to its normal operation.
Overall, "xtrlock" is a simple command-line tool to quickly secure the X display and protect the system from unauthorized access.
