physlock

Physlock is a command line tool designed for Linux systems that helps lock the virtual terminal. It allows users to lock their terminal screen, preventing unauthorized access to their system. The tool is primarily used in situations where multiple users have access to the same terminal, such as public computers or servers.

When physlock is activated, it replaces the user's screen with a black screen, displaying only a lock icon to indicate the lock status. It efficiently prevents any input or output until the correct password is entered. This lock screen ensures that no one can access or view the user's session without permission.

Physlock is lightweight and easily installable from the package manager. It does not have any graphical user interface and works entirely through the command line, making it suitable for headless servers or systems without a graphical environment.

This tool allows users to establish custom lock messages displayed on the lock screen to provide instructions or contact information in case of emergency. Physlock also supports multiple modes of operation, such as daemon mode, which automatically locks the terminal after a specified inactivity period.

Overall, physlock enhances the security of Linux systems by providing a simple yet effective method to protect terminal sessions from unauthorized access.
