diff - How can I see a summary of diffrences when updating working copy to specific revision in SVN -

i svn update between working copy , specific revision.

something like:
svn update (project_directory) -r (revision_number)

how can summery of changes (files added, removed, conflicts, etc.) before doing update?

i tried:
svn diff - --summarize option works between 2 repositories
svn status - works between working copy , head

any idea?
:)

you can specify range diff command. see svn book chapter diff. use:

svn diff -r 300:head 

would give diff between rev 300 , current head revision.

svn diff -r 300 

would give diff between rev 300 , working copy
