in reply to Adding to variable with sprintf()

$page_data = "the cow jump over the moon";
$new = join(" ", grep { length($_) > 3} split(/\s/, $page_data));
print $new;

See perlfunc manpages of split,join and grep for how this works, basically:
  • 1. split makes an array of the original line
  • 2. grep filters for elements longer than 3 chars
  • 3. join glues them together

    Slightly cleaner: 
    $new = join ' ', grep length > 3, split ' ', $page_data;
