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, reboot. If specified, the command
           does not contact the init system. In most cases, filesystems are
           not properly unmounted before shutdown. For example, the command
           reboot -f is mostly equivalent to systemctl reboot -ff, instead of
           systemctl reboot -f.
       -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.
