Let's suppose I have a file like this (but with many more records).
That is a sequence of records, each composed by: a header line, the data list and an end-of-record delimiter ('**').
I'd like to:
1- retain the unique data, that is, excluding duplicate records. This should be done comparing the fields 5, 6, 7, 9 and 10 of the header lines.
2.- list ALL the duplicates (for further examination).
In the example above, it should return:
for the unique, and
for the dupes. Is there a simple way to achieve this?
