Description

The lccCompareCombine was developed to Compare the records in one file (the master) to another file (compare to) on column matches between the two.

Others LCC tools suggested for this type of need:

On records that match, a Combine option allows the combining of columns both one or both of the files into a combined file.

Unmatched records from the master will be copied into an unmatched file.

Another program with many more rule types was developed later, though this one is great for simple column comparisons against small to very large files. Please see lccColumnsCruncher
