Ignore .svn when doing `diff -r`

Question

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/

Solution 1

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

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

Solution 2

  diff --exclude=.svn ...

If you want to exclude multiple items just add another --exclude parameter.

--exclude option is also not working on mac os. -x ".svn" works well.

--exclude works well on macOS 10.15.2, /usr/bin/diff 2.8.1
