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. All three commands take the same options.

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

       Note that on many SysV systems halt used to be synonymous to poweroff,
       i.e. both commands would equally result in powering the machine off.
       systemd is more accurate here, and halt results in halting the machine
       only (leaving power on), and poweroff is required to actually power it
       off.
