NAME
shutdown - bring the system down
SYNOPSIS
shutdown [OPTION]... TIME [MESSAGE]
DESCRIPTION
shutdown
arranges for the system to be brought down in a safe way. All logged-in
users are notified that the system is going down and, within the last
five minutes of
R TIME ,
new logins are prevented.
TIME
may have different formats, the most common is simply the word
'now'
which will bring the system down immediately. Other valid formats are
R +m ,
where
m
is the number of minutes to wait until shutting down and
hh:mm
which specifies the time on the 24hr clock.
Once
TIME
has elapsed,
shutdown
sends a request to the
init(8)
daemon to bring the system down into the appropriate runlevel.
OPTIONS
R -r
Requests that the system be rebooted after it has been brought down.
R -h
Requests that the system be either halted or powered off after it has been
brought down, with the choice as to which left up to the system.
R -H
Requests that the system be halted after it has been brought down.
R -P
Requests that the system be powered off after it has been brought down.
R -c
Cancels a running shutdown.
TIME
is not specified with this option, the first argument is
MESSAGE.
R -k
Only send out the warning messages and disable logins, do not actually
bring the system down.
NOTES
This tool is provided for compatibility with the traditional System V
init(8).
Upstart has no notion of runlevels itself, this and the
telinit(8)
tool are provided to emulate their behaviour.
When invoked it generates a
runlevel
event, with an argument containing the new runlevel.
