in reply to Re: print lines which are not reverse duplicates
in thread print lines which are not reverse duplicates
While you replied to the "code", I replied to the "data"
When looking at the OP's code ...
$_ =~ "$comment_author2,$comment_author1"
it seems like the OP wants to exclude lines of the form personA,personA,10 , i.e. 1. and 2. person are equal
But in the description he asked to exclude the first two lines:
personA,personB,10 personB,personA,190
where the relation was reversed.
