:~# shutdown --help
Usage: shutdown [OPTION]... TIME [MESSAGE]
Bring the system down.
-r reboot after shutdown
-h halt or power off after shutdown
-H halt after shutdown (implies -h)
-P power off after shutdown (implies -h)
-c cancel a running shutdown
-k only send warnings, don't shutdown
-q, --quiet reduce output to errors only
-v, --verbose increase output to include informational messages
--help display this help and exit
--version output version information and exit
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.
Logged in users are warned by a message sent to their terminal, you may include
an optional MESSAGE included with this. Messages can be sent without actually
bringing the system down by using the -k option.
If TIME is given, the command will remain in the foreground until the shutdown
occurs. It can be cancelled by Control-C, or by another user using the -c
The system is brought down into maintenance (single-user) mode by default, you
can change this with either the -r or -h option which specify a reboot or
system halt respectively. The -h option can be further modified with -H or -P
to specify whether to halt the system, or to power it off afterwards. The
default is left up to the shutdown scripts.
