If you’ve ever faced that truly … testing … task of needing to remove a whole heap of hidden .svn directories from a folder and it’s myriad subfolders because some idiot did an SVN Checkout rather than Export to a development server, you’ll love this Terminal command:
find . -name .svn -print0 | xargs -0 rm -rf
You can run it from inside any folder to remove all .svn folders from it and all it’s child folders. Beautiful.
