At present, I've opened a pipe bring the results of tail -f into my script. I'm then running a while loop on the handle. Unfortunately the loop only iterates if tail is providing data.

Is there are way for a while loop to continue to loop even though there is no data being passed to the handle?

open(TAIL, "tail --follow=name logfile.log|") or die "TAIL : $!";
while (<TAIL>) {
        print "matt: $_\n";
        sleep(1);
        # 
        # Should print "matt" once every second regardless if tail is 
+providing data or not

}

Any help would be greatly appreciated! Thanks! Matt
