CPU usage calculation

Hi all
I need to create a shell script to list out only the average of CPU usage for a particular period, and direct it to the file. But when I used "top > top.lis" this output file is in a mesh, how can I extract only the CPU usage at a particular moment? Thanks for help?
Best Regards
Kwang

Kwang,

which OS you are using ?
try e.g.
"iostat -t 10 10 >> /tmp/average.txt"

This will show the overall CPU stat.

Or are you more interested in a special proccess?

No RISK no fun
