Hello everyone,

I need small help in finding duplicates in a file and separating duplicates and distinct records without sorting.

The records should appear in both the output files in the same order as they are in input file.

possible doing that ?

Thanks a lot

Yes, but please give fuller details. RECFM, LRECL, are duplicates contiguous only only, or does the input require sorting to get the matches and then returning to original order?
