Would it not refer to line 3 of the datafile? Not sure, just guessing.

Yeah, that would be overkill :-p
You could easily use sed and awk to transform the input file into a list of SQL
statements. Another solution is to disable all keys on your target table - or create a
duplicate without any keys - and after the import run a select (unique key fields) group
by (unique key fields) having count(*) > 1.
