The method appears similar to what is used in GnuWin32 sort. There is a significant difference though - there doesn't appear to be a way to shut off that "final key" approach. In GnuWin32 sort, there are two ways - specifying a stable sort (-s) or specifying unique keys (-u). Otherwise, the docs imply that they behave quite similarly. -- Best regards, Bill
