Duplicate files into same directory and rename them
I'm plodding my way through UNIX for Mac OS X and have come up against something that seems like it should be pretty easy, trouble is, I can't seem to conjure the correct unix incantation. Could someone show me how to do the following?

I want to duplicate all files ending with ".JPG" back into the same directory and rename the copies by changing the name suffix from ".JPG" to "_gray.JPG". Tips?

Thanks

Ken
