POWERDOWN(1M) (Essential Utilities) 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 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 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.
