I was looking for a way to copy/move files within the same share or maybe different shares using smbclient. You can do it with mount, but doing it with smbclient would be a lot easier. Please let me know if this is likely to be done
There is an extremely old SMBmv protocol op that no one uses. We could perhaps do this in smbclient, but this is probably not a high priority given other pressing issues. If you could write up a patch, I'd be glad to review it.
