[svn] How to view changes made to files on a certain revision in Subversion

I am looking for a Subversion command which does the equivalent of

git show <commit-number>

Call this in the project:

svn diff -r REVNO:HEAD --summarize

REVNO is the start revision number and HEAD is the end revision number. If HEAD is equal to the last revision number, it can skip it.

The command returns a list with all files that are changed/added/deleted in this revision period.

The command can be called with the URL revision parameter to check changes like this:

svn diff -r REVNO:HEAD --summarize SVN_URL

The equivalent command in svn is:

svn log --diff -r revision
