Hello,

I'm having a problem sorting between two files that I hope someone can help me with as I'm still pretty new to Perl.

I need to separate all values where key 1 first page third column is != key 2 second page third column and then print those lines to another external page sequentially from the two.

The trick is that the file has 90k+ entries and line 1 may have duplicates such as 'Scott' more than once which I would like to keep, only eliminating those values where 'Scott' shows in line key 1 & 2 of the same second column value.

A sample of the first file looks like this:

The second file looks like this:

My desired results would be this:

I've been through many pages of @array, %hash and awk trying to modify it to suit my needs but have not been able to get a working solution yet as most of them are only trying to remove one duplicate line.

A little help PLEASE!
