## NAME
       telinit - Change SysV runlevel

## SYNOPSIS
### telinit [OPTIONS...] {COMMAND}

## DESCRIPTION
       **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       is obsolete the runlevel requests will be transparently translated into systemd unit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.

## OPTIONS
       The following options are understood:

### --help
           Print a short help text and exit.

### --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**.

## EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise.

## NOTES
       This is a legacy command available for compatibility only. It should not be used anymore, as
       the concept of runlevels is obsolete.
