in reply to How to UPDATE rather than append to STDOUT?

Short of using the various terminal manipulation tools you could use the funky backspace character \b 
$|++;
print "  ";
for (0..20) {
    select undef, undef, undef, 0.25;
    print "\b\b";
    printf "%2d", $_;
}
print "\n";

That isn't the greatest example but I'm sure you get the picture ;-)
