For your code at the bottom that runs the 'while (<@aoutput>)', you could do somthething like this (my own test code): 
@a = qw(a b c d e f);
@b = qw(1 2 c 3 4 f);

foreach $foo (@a) {
   if ( grep /$foo/, @b ) {
      print "Matched $foo in both arrays\n";
   }
}

The above only works if both arrays are populated of course (but will return nothing if an either array is empty). There's probably better ways to do this but it's a good Q&D, hehe...
