sounds about right.
Just remember - whatever you do, comparing 60G files will be slow...
Test this on a smaller chunks to see if you're getting the desired results first.

Hi kartikirans,

I'd be tempted to look at comm -3 ${file1} ${file2} this will suppress lines common to ${file1} and ${file2} later versions of comm don't require the files to be sorted.

Regards

One additional question: what means "non-matching lines"?

- only Lines in file1 which are not in file2? or
- plus lines in file2 which are not in file1?
