I'm writing a wrapper around a large number of rsyncs that need to happen, and it would be great if I could parse the output of a running rsync and find out how far along it is. To do this, I would need to know how many files the rsync is going to transfer. If I run 'rsync -avz --progress', it tells me how many files it is considering, but not how many it actually needs to update.
