I'm new to programming using PERL and I have a question that I can't seem to find all my answers. What I have is 2 csv files that I want to compare. Each have the same headings but sometimes different data.
For instance:
file1
KellyTerms,LName,FName,...
Kelly,Doe,John,...
Kelly,Doe,Jane,...

file2
KellyTerms,LName,FName,...
Kelly,Hancock,John,...
Kelly,Doe,John,...

What I want to return is the contents of file2. However, when the rows are the same in file1 and file2, I want to add a column to the end of that row to include the words "duplicate".

So for the above examples the output would be
outputfile
KellyTerms,LName,FName,...,Duplicate
Kelly,Hancock,John,...
Kelly,Doe,John,...,Duplicate

Can anyone guide me in the right direction?
