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, when either
halt
or
poweroff
is invoked. This option is ignored when
reboot
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 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.
