       halt, poweroff, reboot may be used to halt, power-off or reboot the machine.

OPTIONS

       The following options are understood:

       --help
           Print a short help text and exit.

       --halt
           Halt the machine, regardless of which one of the three commands is invoked.

           Power-off the machine, regardless of which one of the three commands is invoked.

       --reboot
           Reboot the machine, regardless of which one of the three commands is invoked.

       -f, --force
           Force immediate halt, power-off, or reboot. When specified once, this results in an immediate but
           clean shutdown by the system manager. When specified twice, this results in an immediate shutdown
           without contacting the system manager. See the description of --force in systemctl(1) for more
           details.

       -w, --wtmp-only
           Only write wtmp shutdown entry, do not actually halt, power-off, reboot.

       -d, --no-wtmp
           Do not write wtmp shutdown entry.

       -n, --no-sync
           Don't sync hard disks/storage media before halt, power-off, reboot.

       --no-wall
           Do not send wall message before halt, power-off, reboot.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.

NOTES

       These commands are implemented in a way that preserves compatiblity with the original SysV commands.
       systemctl(1) verbs halt, poweroff, reboot provide the same functionality with some additional features.
