Inverse Output File - ID the Uniques, Not the Dupes

[cjaccino]

rdfind is a great tool! Love it.

One feature I'd love to see would be an output file containing the uniques, rather than the dupes.

In my use case, I have significant duplication across multiple volumes. I am trying to get back to a single, rational volume containing a single copy of my files. Once I know I've IDed and moved all of the valuable stuff, I will throw away the old filesystem. Having the uniques in my source volume(s) relative to my target volume would be very enabling.

I realize that this can be done by taking a list of a source volume and pruning the dupes from the list, but it seems like an easy feature to add to rdfind, given that it has the list in memory.

Cheers!
