NAME
telinit - change system runlevel
SYNOPSIS
telinit [OPTION]... RUNLEVEL
DESCRIPTION
telinit may be used to change the system runlevel.
The RUNLEVEL argument should be one of the multi-user runlevels 2-5, 0
to halt the system, 6 to reboot the system or 1 to bring the system
down into single-user mode.
Normally you would use the shutdown(8) tool to halt or reboot the sys‐
tem, or to bring it down to single-user mode.
RUNLEVEL may also be S or s which will place the system directly into
single-user mode without actually stopping processes first, you proba‐
bly won't want that.
The runlevel is changed by emitting the runlevel(7) event, which
includes the new runlevel in the RUNLEVEL environment variable as well
as the previous runlevel (obtained from the environment or from
/var/run/utmp) in the PREVLEVEL variable.
telinit will write the new runlevel to /var/run/utmp and append a new
entry to /var/log/wtmp.
Other commands
telinit may be also used to send basic commands to the init(8) daemon
for compatibility with System V. These are:
Q or q to request that init(8) reload its configuration. This is
rarely necessary since Upstart watches its configuration with
inotify(7) and is deprecated by the initctl(8) reload-configura‐
tion command.
U or u to request that the init(8) daemon re-execute itself. This is
necessary when upgrading the Upstart init(8) daemon itself or
any of its dependent system libraries to ensure disks can be
unmounted cleanly on shutdown.
Note that if the init daemon is not Upstart, this option will
have no effect on the running init(8) daemon.
OPTIONS
-e KEY=VALUE
This specifies an additional environment variable to be included
in the event along with RUNLEVEL and PREVLEVEL.
ENVIRONMENT
RUNLEVEL
telinit will read the current runlevel from this environment
variable if set in preference to reading from /var/run/utmp
FILES
/var/run/utmp
Where the current runlevel will be read from; this file will
also be updated with the new runlevel.
/var/log/wtmp
A new runlevel record will be appended to this file for the new
runlevel.
NOTES
The Upstart init(8) daemon does not keep track of runlevels itself,
instead they are implemented entirely by its userspace tools.
See runlevel(7) for more details.
