1. Something like this might work: 
    sub scan {
  $listbox->insert('end', "Scanning...");
  open CMD, 
    qq[perl -lne "foreach (glob '$_/*'){print if !/Makefile[.inc]*$/}"
+ zz.lis] 
    or die $!;
    
  while( <CMD> ) {
      chomp;
      $listbox->insert( 'end', $_ );
      DoOneEvent();
  }
  $listbox->insert('end', "Done.");
}

    Though you should probably look at Tk::Event and/or Tk::fileevent

  2. On win you could use dir /b /a:d | find /v "Mk" | find /v "Templates" |find /v "Tools" | find /v "distfiles"
