NAME

halt − stop the processor

SYNOPSIS

/etc/halt [ −n ] [ −q ] [ −y ]

DESCRIPTION

The halt command stops all but one processor, runs the command script rc.shutdown with the argument halt, executes a sync system call, and then stops the remaining processor.  The machine does not reboot, even if auto-reboot mode is selected on the front panel. 

The −n and −q options prevent the sync before stopping.  In addition, the −q option causes the system to halt quickly without executing the shutdown script; this option is not recommended except in an emergency.  Use the −y option if you are trying to halt the system from a dialup.
