NAME
       halt, poweroff, reboot - Halt, power-off or reboot the machine

SYNOPSIS
       halt [OPTIONS...]

       poweroff [OPTIONS...]

       reboot [OPTIONS...]

DESCRIPTION
       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.

       -p, --poweroff
           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 compatibility with the original
       SysV commands.  systemctl(1) verbs halt, poweroff, reboot provide the same functionality
       with some additional features.
