shutdown(1m)               DG/UX 4.30                shutdown(1m)



     NAME
          shutdown - shut down system, change system state

     SYNOPSIS
          /etc/shutdown [ -y ] [ -ggrace_period [ -iinit_state ]

     DESCRIPTION
          This command is executed by the superuser to change the
          state of the machine.  By default, it brings the system to a
          state where only the operator console has access to the UNIX
          system.  This state is traditionally called "single-user".

          The command sends a warning message to all of the terminals
          (all the people currently logged in) and a final message
          before it starts actual shutdown activities.  By default,
          the command asks the user at the console for confirmation
          before it starts shutting down daemons and killing
          processes.  The options are used as follows:

          -y   pre-answers the confirmation question so the command
               can be run without user intervention.  A default of 60
               seconds is allowed between the warning message and the
               final message.  Another 60 seconds is allowed between
               the final message and the confirmation.

          -ggrace_period
               allows the superuser to change the number of seconds
               from the 60-second default.  grace_period is expressed
               in seconds:  g300 gives a 5-minute warning.

          -iinit_state
               specifies the state that init(1M) is to be put in
               following the warnings, if any.  By default, system
               state "s" is used.

          Possible system states are:

          state s, S
               Bring the machine to the state traditionally called
               single-user.  The /etc/rcS.d rc scripts are called to
               do this work.  All processes are killed and all file
               systems other than root are unmounted.

          state 1
               Bring the machine to the state called the administrator
               run level.  Both /root and /usr will be mounted, and
               the update demon will be running. If specified in the
               /etc/inittab/ file, optional "administrative" terminals
               will have gettys spawned.
