systemctl-poweroff

Power off the system

$ systemctl poweroff

$ systemctl poweroff -f

$ systemctl poweroff -f --no-wall

systemctl poweroff [OPTIONS]

systemctl poweroff shuts down the system and powers off the machine. It gracefully stops all services, unmounts filesystems, and then signals the hardware to power down.
With `--force`, services are not gracefully stopped. With double `--force`, filesystems aren't unmounted, risking data loss.

-f, --force

Skip graceful service shutdown

Immediate poweroff without cleanup (dangerous)

Don't send wall message to logged-in users

Schedule poweroff at specific time

Requires appropriate privileges. Force mode can cause data loss if filesystems aren't properly synced. Some hardware may not support software poweroff and will halt instead.

The poweroff subcommand provides systemd-native shutdown, integrating with the scheduled shutdown mechanism and wall notification system.
