## 12.5. Shutdown Sequence

Upon controlled shutdown using shutdown(8), init(8) will attempt to run the script `/etc/rc.shutdown`, and then proceed to send all processes the `TERM` signal, and subsequently the `KILL` signal to any that do not terminate in a timely manner.

To power down a FreeBSD machine on architectures and systems that support power management, use `shutdown -p now` to turn the power off immediately. To reboot a FreeBSD system, use `shutdown -r now`. One must be `root` or a member of `operator` in order to run shutdown(8). One can also use halt(8) and reboot(8). Refer to their manual pages and to shutdown(8) for more information.

Modify group membership by referring to Section 3.3, “Users and Basic Account Management”.

### Note:

Power management requires acpi(4) to be loaded as a module or statically compiled into a custom kernel.
