Shutting Down, Restarting, Suspending, and Hibernating the Operating System
systemctl Command
The systemd uses the systemctl command instead of old Linux system management commands to shut down, restart, suspend, and hibernate the operating system. Although old Linux system management commands are still available in systemd for compatibility reasons, but it is advised that you use systemctl when possible.

systemctl --no-wall poweroff
