What those files look we dont know unless you post a sample of org.csv and dup.csv.

Are they in the same order? Will they ever have different numbers of lines? A simple solution for line-matching might just be:

diff a.csv b.csv | grep '^> ' | sed 's/> //' > diff-file

The output was in CSV. Have you tried it to see if it does what you want?

Try this:
Code:
grep -F -v -f CSV1 CSV2

It presumes sorted data and CSV2 file is with more lines.
