svn diff: Compare my local uncommited changes with an arbitrary version of the file from the repository

Question

Let's say I've checked out revision 10 of hello.c which is the latest one in the repository. I've made some changes to hello.c locally in my workspace, but I haven't committed it yet. Now, how can I compare this local uncommitted changes made on top of revision 10 with, say, revision 7 of hello.c in the repository?

Thanks for your time!

Answer 1

svn diff -r 7 hello.c

Answer 2

According to: http://svnbook.red-bean.com/en/1.0/re09.html

--revision N The client compares TARGET@N against working copy.

So it would be

svn diff -r 7 hello.c
