diff has an option --recursive (-r) to do a comparison between two directories (the files inside them). Is there a way to make diff ignore certain sub-directories (eg: .svn)?

$ diff -r src1/ src2/

Add --exclude=".svn" as an option like so:

$ diff -r --exclude=".svn" src1/ src2/

If you want to exclude multiple items just add another --exclude parameter. – JonMR Jul 12 '11 at 16:02
If you don't want to type --exclude every time use -x ".svn" – Aug 14 '12 at 9:03
--exclude option is also not working on mac os. -x ".svn" works well. – alpert Mar 29 at 11:13
  diff --exclude=.svn ...
