The command "halt" is used to shut down a computer or stop its operation completely. When this command is executed, it triggers an ACPI (Advanced Configuration and Power Interface) signal that instructs the operating system to perform a controlled and graceful shutdown. By issuing the "halt" command, all running processes and tasks are terminated, and the computer's power is turned off or halted. It is important to note that this command usually requires administrative privileges to execute.
