stop all processes and turn off the power

From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

powerdown - stop all processes and turn off the power

SYNOPSIS

powerdown [ -y | -Y ]

DESCRIPTION

The powerdown command brings the system to a state where nothing is running and then turns off power. The command invokes a visual interface (the powerdown task available through the sysadm(1M) command). You are asked questions that control how much warning the other users are given. The options are:

-y prevents the questions from being asked and just gives the warning messages. There is a 60-second pause between the warning messages.

-Y   is the same as -y except that it has no  pause  between
     messages.   It  is  the fastest way to bring the system
     down.  The identical function is  available  under  the
     sysadm menu:
     sysadm powerdown
This command may be assigned a password with the sysadm sys-
temsetup password(1M) command.
