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.

    If you don't want to type --exclude every time use -x ".svn"

    --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 Mar 9, 2021 at 13:00
