Thanks a ton, Corona688! I'm not sure if I was clear in my previous post. Basically, I also have files of about 15GB size. So if I take one of these files, the sample data would look like this-

72426459560 2010-06-2 ABC LC11100619758

95327GNFA4S 2010-06-2 ABC 97BCX3AMD10G

95327GNFA4S 2010-06-2 ABC 97BCX3AMKLMO

900278VGA4T 2010-06-2 ABC QVA697C8LAYMACBF

900278VG567 2010-06-2 ABC QVA697C8LAYMACBF

(column 3 would be the same for the entire 15GB file)

From this file: I want to find duplicates in column one and four. The output would look something like this:

5327GNFA4S 2010-06-2 ABC 97BCX3AMD10G

95327GNFA4S 2010-06-2 ABC 97BCX3AMKLMO

900278VGA4T 2010-06-2 ABC QVA697C8LAYMACBF

900278VG567 2010-06-2 ABC QVA697C8LAYMACBF

I can use a code that will find me duplicates only in column 1 and save it in file ABC.txt. Then rerun the same code to find duplicates in column 4 and save it in ABC2.txt. Two different files..

I want to save all the duplicates with original records (as in the example above) in a new CSV file.
