true. comm is also a good way to do that. Looping through the text file gives the added advantage of being able to discriminately direct the text based on matches, which would otherwise need multiple incantations of comm. Thanks for pointing me to the readme, I think those methods ought to do it for me.

    Algorithm::HowSimilar is probably the fastest solution but only because it uses the excellent Algorithm::Diff module. 

    use Algorithm::HowSimilar 'compare';
my (     $av_similarity,
         $sim_ary1_to_ary2,
         $sim_ary2_to_ary1,
         $ref_ary_matches,
         $ref_ary_in_ary1_but_not_ary2,
         $ref_ary_in_ary2_but_not_ary1
       ) = compare( \@ary1, \@ary2 );
