POWERDOWN(1M)                                       POWERDOWN(1M)



     NAME
          powerdown - stop all processes and turn off the power

     SYNOPSIS
          powerdown [ -y | -Y ]

     DESCRIPTION
          This command brings the system to a state where nothing is
          running and then turns off the power.

          By default, the user is asked questions that control how
          much warning the other users are given.  The options:

          -y   prevents the questions from being asked and just gives
               the warning messages.  There is a 60 second pause
               between the warning messages.  Note that pressing the
               standby button on the side of the cabinet will
               accomplish the same thing.

          -Y   is the same as -y except it has no pause between
               messages.  It is the fastest way to bring the system
               down.

          The identical function is also available under the sysadm
          command:
               sysadm powerdown

          Password control can be instituted on this command.  See
          sysadm(1), admpasswd sub-command.

     EXAMPLES
               some-long-running-command;  powerdown -y

          The first command is run to completion and then the machine
          turns off.  This is useful for, say, formatting a document
          to the printer at the end of a day.
