Usage: shutdown [OPTION]... TIME [MESSAGE]

Bring the system down.

Options:

  -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

option.

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.
