NAME

halt − stop the processor

SYNOPSIS

/usr/etc/halt [ −e ] [ −n ] [ −p ] [ −q ] [ −y ]

DESCRIPTION

Halt flushes internal caches, ensures that all remaining disk writes have been completed, and then stops the processor.  The machine doesn’t reboot. 

The −e option causes the optical drive to eject any disk contained in it.  The −n option prevents the sync before stopping.  The −p option causes the machine to be powered down after shutdown.  −q option causes a quick halt, no graceful shutdown is attempted.  The −y option is needed if you are trying to halt the system from a dialup. 

Halt normally logs the shutdown using syslog(8) and places a shutdown record in the login accounting file /usr/adm/wtmp. These actions are inhibited if the −n or −q options are present.
