Stopping a command in between

Hi
Is it possible to stop a command executing after certain time?
I have this command say prstat which keeps on giving the values etc of the processes after every 1 sec(refreshes the screen)
What I want is just stop the execution after first screen

Since I have written this command in shell script, I am not sure how I can stop it so that my script continues on the next line(right now it keeps on waiting for the output of this command)
Can someone help?

San

NAME
topsysproc - top syscalls by process name. Uses DTrace. SYNOPSIS
topsysproc [-Cs] [interval [count]] DESCRIPTION
This program continually prints a report of the number of system calls by process name, and refreshes the display every 1 second or as specified at the command line. Similar data can be fetched with "prstat -m". Since this uses DTrace, only users with root privileges can run this command. OPTIONS

There may be several PIDs with the same process name. DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver- bose descriptions explaining the output. EXIT
