Need a REGEX to increment the file number of a pdf file

Hello,

I have a few thousand .pdf files in various folders each have a naming scheme like this:

006_-_Titled_Document_#34_-_September-25-2011-side-1.pdf

In each folder, the number system starts at 001 (as you see on the far left of the file name), and then ends at 999 (maximum .pdf files).

Somewhere in the collection of files say .pdf # 286, I have 286 twice (duplicate). Which screws up my numbering system.

I need a REGEX that I can enter into the shell when I'm in the .pdf directory, and start from say the duplicate # 286 and increment that 2nd duplicate # 286 & all the numbers after that by +1. So that they are all renamed appropriately.

This way I don't have to go in there and rename each .pdf file manually one by one.

Unfortunately, I am not very good with REGEX and haven't had much need for it in the past until now.

Would anyone know the best way to automate this .pdf renumbering task? I would appreciate any constructive thoughts on how to accomplish this.

Thank you.
