shutdown - bring the system down
shutdown [OPTION]... TIME [MESSAGE]
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 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 +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.
-r Requests that the system be rebooted after it has been brought
-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
-H Requests that the system be halted after it has been brought
-P Requests that the system be powered off after it has been
-c Cancels a running shutdown. TIME is not specified with this
option, the first argument is MESSAGE.
-k Only send out the warning messages and disable logins, do not
actually bring the system down.
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.
