Thank you JasKinasis. Yes, two files could have the same name, but may have different content. Any slight change an engineer makes to the CAD design would change the content. So the duplicates can be alike in name, but different in content.
I want to add some clarifying remarks that might help...
I am current counting files of the form ??-????-????-?.prt on root using the following syntax:
[~] find / -iname "??-????-????-?.prt" | wc -l
It works, and returns a number, but I am not sure this gives me a recursive search count or not.
I also want to be able to count duplicates of this file...
