Check to see if there are changes using rsync

[Daniel Bolgheroni]

Hi rsync@,

Is it possible to use rsync to check if there are changes in the files I'm
trying to sync, but just to check?

I need to check if the files I have in a local directory differs from
the files in an anonymous rsync server.

I'm willing to use -anv (-n for --dry-run) and parse the output. But
maybe there is an easier way? Maybe some status returned given a
specific set of parameters?

Thank you.
