Question

Can someone give me an example of using sigalarm and alarm to print a smiple message at an interval, like every 5 seconds? I am having trouble getting this to work.

Second, would such a process run in the background? Or would it take the focus?

Code:
print "Tell me something....\n";

eval
{
    $SIG{ALRM} = sub { die "Timeout"; };
    alarm 10;
    $input = <STDIN>;
    alarm 0;
}

if($@ && $@ =~ /Timeout/) {
    print "You didn't tell me anything!\n";
} else {
    print "You said: " . $input;
}

You should be able to figure it out from my example here.
