Shell Programming and Scripting

Hi all,

I need a script that will check the cpu usage of a certain process and then kill the process if the % cpu is greater than 25%.

I know i can get the pid of a process by doing pidof <processname>.

Once I have the pid number is there a command in bash to return the current % cpu?

Linux: ps -aux
Solaris:/usr/ucb/ps -aux

I got it using this

PIDIDOFLTSESSION=`pidof vmware-vmx`
PERCENTAGECPUOFLTSESSION=`top -p $PIDIDOFLTSESSION -n 1 -b | grep $PIDIDOFLTSESSION | awk '{print $9}'`
#echo $PIDIDOFLTSESSION
#echo $PERCENTAGECPUOFLTSESSION
INTPERCENTAGECPUOFLTSESSION=`echo $PERCENTAGECPUOFLTSESSION | bc | sed 's/[.].*//'`
if [ $INTPERCENTAGECPUOFLTSESSION -gt 5 ]
then echo "its greater than 5"
else echo "its less than 5"
fi
