-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is it actually not doing anything? It should only list files that it is actually doing something with unless you use more than one -v. Try adding --itemize-changes to find out (-v is fairly useless without it anyway).

Using -r and -a at the same time is just extra typing it will not cause any problems. On 03/01/12 15:49, Colin Raven wrote: > Thanks to all for jumping in on this one.
