I'm looking to use perl to help in our data processing with regard to generating a sample file which show all field variants over various different files from the least number of records.

For example, we have 5 comma separated data file with 20 fields and we have been asked to show all variants contained in each of 3 of the fields over the 5 files in the least number of records.

I could do with having a program that allows me to define as many fields as I want from any csv database and generate a sample file which shows ALL the variants from those fields in the least number of records.

I'm struggling to get my head around how to code efficiently for this so any help would be most welcome.

Cheers

Kray
