HALT(8) halt HALT(8)
halt, poweroff, reboot - Halt, power-off or reboot the machine
halt [OPTIONS...]
poweroff [OPTIONS...]
reboot [OPTIONS...]
halt, poweroff, reboot may be used to halt, power-off, or reboot the
machine. All three commands take the same 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.
On success, 0 is returned, a non-zero failure code otherwise.
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.
