You can use the sleep command to wait some time in a script. Eh.

echo "before"
sleep 5
echo "5 seconds later"

And so on. Does that help?

Have you considered using the command "time" instead of "htop"?

Thanks your help , andrew . I know your mean is to write a shell which sleep per certain time to record . Even through now I don not know how to grab data from htop , this dynamic window. Maybe I need read some tutorial beyond htop.

Thanks you , m-hampl. I check command 'time' and it does provide the function which show the runtime of a program . But in my case , the program is working for a while so its needless to compare start time . Anyway thank you!
