Re: sleep in infinite loop

Flush the output:

#!/usr/bin/perl
use warnings;
use strict;

$| = 1;

while (1) {
        sleep 5;
        print "interval";
}

Ending the line will also force it to display immediately, so `print "interval\n"` will fix this. It's also probably what the OP actually meant to do, unless he wanted to see "intervalintervalinterval..." all the way across the screen.	[reply] [d/l]
