Small logic error which you catch after the fact in your output loop.

Assuming unique values in each file, your loops can be reduced to

foreach my $entry (@file1) { $index{$entry} = 1 } foreach my $entry (@file2) { $index{$entry} += 2; }

Not assuming unique values, to avoid "screwed up" entries, it could be reduced to this

foreach my $entry (@file1) { $index{$entry} = 1 } foreach my $entry (@file2) { # '||0' is to still the warnings under 'use warnings' $index{$entry} += 2 if (($index{$entry}||0) < 2); }

Nothing big.
