shutdown(1M_BSD)     (BSD System Compatibility)     shutdown(1M_BSD)


       NAME
             shutdown - (BSD) close down the system at a given time

       SYNOPSIS
             /usr/ucb/shutdown [-fhknr] time [warning-message . . . ]

       DESCRIPTION
             shutdown provides an automated procedure to notify users when
             the system is to be shut down.  time specifies when shutdown
             will bring the system down; it may be the word now (indicating
             an immediate shutdown), or it may specify a future time in one
             of two formats: +number and hour:min.  The first form brings
             the system down in number minutes, and the second brings the
             system down at the time of day indicated in 24-hour notation.

             At intervals that get closer as the apocalypse approaches,
             warning messages are displayed at terminals of all logged-in
             users, and of users who have remote mounts on that machine.

             At shutdown time a message is written to the system log
             daemon, syslogd(1M), containing the time of shutdown, the
             instigator of the shutdown, and the reason.  Then a terminate
             signal is sent to init, which brings the system down to init
             state 1.

       OPTIONS
             As an alternative to the above procedure, these options can be
             specified:

             -f    Arrange, in the manner of fastboot(1M_BSD), that when
                   the system is rebooted, the file systems will not be
                   checked.

             -h    Execute halt(1M_BSD).

             -k    Simulate shutdown of the system.  Do not actually shut
                   down the system.

             -n    Prevent the normal sync(2) before stopping.

             -r    Execute reboot(1M_BSD).

       FILES
             /etc/xtab           list of remote hosts that have mounted
                                 this host

      NOTICES
            Only allows you to bring the system down between now and 23:59
            if you use the absolute time for shutdown.
