Combine ps(1) and standard FreeBSD tools to filter out a process listing,
and keep only those fields you want (in this case, the PID of the
processes).  Look at the output of the following shell script on your
system:

	#!/bin/sh

	ps xau | sed -e 1d | grep -v '^root' | grep -v "^${USER}" |\
	    awk '{print $2,$7}' | grep '??$' | cut -d' ' -f1

Try removing parts of this pipeline, and see what you get as output.
If you manage to get a listing of the process IDs like the one produced by
the above script, you can easily call kill to do the rest:

	$ kill `script.sh`
