physlock:tldr:e8555

This command is using the physlock utility with the -p option to lock the physical console by displaying a custom message.

Here is a breakdown of the command:

• physlock: It is a command-line utility used to lock the physical console of a system.
• -p: It is an option that specifies the custom message to display on the locked console.
• "${Locked!}": This is the custom message that will be displayed on the locked console. The message "Locked!" has been used as an example, but you can replace it with any other desired text.

When this command is executed, the physical console will be locked, and the message "Locked!" (or any other specified text) will be displayed until the console is unlocked again.
