How to make a non-efective update?

Hi,

I was using CVS in the past and one of the most useful commands was a :

$ cvs -nq update

With the -n flag you could execute a recursive update that showed the list
of files changed/added/deleted etc... but the update did not take effect, it
was just for information...

Is there any way to do this in svn using the command line client?
I have checked the documentation and can't see that option for the update
command Sad

Thanks in advance
