telinit - Change SysV runlevel
may be used to change the SysV system runlevel. Since the concept
of SysV runlevels is obsolete the runlevel requests will be transparently
translated into systemd unit activation requests.
The following options are understood:
Print a short help text and exit.
Do not send wall message before
The following commands are understood:
Power-off the machine. This is translated into
an activation request for poweroff.target and is equivalent to systemctl
Reboot the machine. This is translated into an
activation request for reboot.target and is equivalent to systemctl
Change the SysV runlevel. This is translated
into an activation request for runlevel2.target, runlevel3.target, ... and is
equivalent to systemctl isolate runlevel2.target, systemctl isolate
Change into system rescue mode. This is
translated into an activation request for rescue.target and is equivalent to
Reload daemon configuration. This is
equivalent to systemctl daemon-reload.
Serialize state, reexecute daemon and
deserialize state again. This is equivalent to systemctl
On success, 0 is returned, a non-zero failure code otherwise.
This is a legacy command available for compatibility only. It should not be used
anymore, as the concept of runlevels is obsolete.
