There isn't really an option to do it, but if you use rsync to do a
pull from an rsync daemon, then you can get the information you want
by using the syntax:
rsync [options] rsync://remotehost/module
i.e., use the same command that you would use to sync a tree but do
not specify a target. Here's an example:
alberto@guinan-923: rsync rsync://rsync.samba.org/rsyncftp/'*'

I actually have a couple of complaints about this "feature:"
1) if a directory is included in the file list, the rsync server does
not display the information you'd expect but rather says "skipping
directory xxx". Try for instance rsync rsync://rsync.samba.org/ftp/'*'
2) the output contains "welcome" messages, which makes it hard to
parse in a simple programmatic way
3) it only works in rsync daemon mode -- why shouldn't we be allowed
to do the same thing when using a remote shell? I realize that you
can generate similar output by doing something like:
ssh remotehost /bin/ls -l /foo/bar
but the output of ls is not always guaranteed to be consistent
across operating systems
A while ago I was thinking about either modifying the daemon output
to address (1) and (2) in daemon mode, or maybe by adding a
new option (--list), but then got sidetracked and ended up doing
things differently.
Hope this helps,
-- Alberto
