systemd telinit 8 telinit Change SysV runlevel telinit OPTIONS COMMAND telinit 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 Since the concept of SysV runlevels is obsolete the runlevel requests will be transparently translated into systemd unit activation requests.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: --help --no-wall Do not send wall message before reboot/halt/power-off. The following commands are understood: 0 Power-off the machine. This is translated into an activation request for poweroff.target and is equivalent to systemctl poweroff. 6 Reboot the machine. This is translated into an activation request for reboot.target and is equivalent to systemctl reboot. 2 3 4 5 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 runlevel3.target, … 1 s S Change into system rescue mode. This is translated into an activation request for rescue.target and is equivalent to systemctl rescue. q Q Reload daemon configuration. This is equivalent to systemctl daemon-reload. u U Serialize state, reexecute daemon and deserialize state again. This is equivalent to systemctl daemon-reexec. 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 It should not be used anymore, as the concept of runlevels is obsolete. systemd1 systemctl1 wall1
