poweroff

Poweroff is a command line tool used to shut down or power off a computer running a UNIX-like operating system. It is typically used when an administrator or a user wants to turn off the system cleanly without any interruptions. When the poweroff command is executed, it sends a signal to the init process, which is responsible for controlling the shutdown process. The init process then proceeds to initiate the shutdown sequence, terminating all running processes and unmounting the file systems before powering off the system. This tool generally requires administrative privileges to execute, as it affects the entire system's functionality. The poweroff command is often used in scripting and automation tasks or by administrators to remotely power off multiple systems in their network. It is crucial to use this command with caution since it can cause data loss if used carelessly.
