24
25       --halt
26           Halt the machine, regardless of which one of the three commands is
27           invoked.

33       --reboot
34           Reboot the machine, regardless of which one of the three commands
35           is invoked.
36
37       -f, --force
38           Force immediate halt, power-off, or reboot. When specified once,
39           this results in an immediate but clean shutdown by the system
40           manager. When specified twice, this results in an immediate
41           shutdown without contacting the system manager. See the description
42           of --force in systemctl(1) for more details.
43
44       -w, --wtmp-only
45           Only write wtmp shutdown entry, do not actually halt, power-off,
46           reboot.
47
48       -d, --no-wtmp
49           Do not write wtmp shutdown entry.
50
51       -n, --no-sync
52           Don't sync hard disks/storage media before halt, power-off, reboot.
53
54       --no-wall
55           Do not send wall message before halt, power-off, reboot.

EXIT STATUS

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

NOTES

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