help on running a report on dirs permissions that differ from above

[Guest]

I'm trying to run a report on all of our servers that list NTFS rights that are different the directories above it. When I run dumpsec I get All the directories and their rights, not just the ones that are different - am I missing something?

the line I'm using is:
dumpsec /computer=\\aserver /rpt=dir=\\aserver\c$ /noowner /noheader /showexcdirs /outfile=test4.txt /saveas=tsv
