hello. i have 2 similar files and id like to compare them by words to know how many words are different. file sizes of both files are same. what would be the best way to do that? thanks i was thinking about something like this: 

$good=0;
$bad=0;
while ((defined ($line1 = <INPUT1>)) && (defined ($line2 = <INPUT2>)))
{
@words1 = split(/ /, $line1);
@words2 = split(/ /, $line2);
$wordsno = @words2;
until ($wordsno-- == 0){
    if ($words1[$wordsno] eq $words2[$wordsno]) { $good++; }
    else {$bad++;}
    }
}

print "good: $good";
print "bad: $bad";
close INPUT1;
close INPUT2;

and it works :)
