POWERDOWN(1M-SysV)  RISC/os Reference Manual   POWERDOWN(1M-SysV)



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.
