I'm afraid you mixed up the files (compared to post#1). Ploughing through huge files multiple times may be very time consuming... Did you consider to read man comm, here the -1 and -2 options?

Hi RudiC

I checked this option as well.

Really helpful if you make changes in below sort command to get differences in file2 as compared to file 1.

Code:
sort file[12] | tr '.' ',' | uniq -u
