while (<$filename>){

I don't understand. If  /$id1/g && /$id2/g ever becomes true (matching by default against  $_ assigned in the outer while-loop), when will it ever become false? I.e., isn't this an infinite loop? And what's the point of the  /g modifier in these regexes? And yes,  $filename is a terrible name for a file handle!

Update: I should have known. Many thanks, choroba. (But  $filename is still terrible!)
