and specially for Sebastien DAUBIGNE, because i will use his command in
my crontab:
ps -eo pcpu,pid,args | awk '/netscape/ && $1 > 5 {print $2}' | xargs -n
10 kill -9

my first mail was not so clear, i want to automatically kill process
such netscape because they are bugged, i don't want to do it by hand.
Here is some contributions:

******************************************************************************
form Evans, Shawn:
#!/bin/sh

PROC=netscape

NUM=50

CPU=`prstat 1 1 | grep $PROC | awk '{print $9}' |awk -F. '{print $1}'`

if [ $CPU -ge $NUM ] ; then

kill -9 `ps -ef | grep -i $PROC`

from Alex J. Avriette:
is there something wrong with ps -ef | grep netscape | awk '{ print $2 }'

******************************************************************************
from Karl Vogel:
You might want to do it by hand using the script below; it looks for

the processes on the command line and puts you in VI to pick the
ones
you want to kill.
