Ok, some posts are clearly just to help me remember how to do things… this is one of them. The Subversion source control system keeps private information in .svn directories. There is one such directory for EVERY directory in your source tree. Here’s how you recursively delete ALL the .svn directories from the current directory in Linux (or Cygwin in Windows).
rm -rf `find . -type d -name .svn`
NOTE: Those are back ticks around the ‘find’ command, not apostrophes. I recommend you just run the ‘find’ command first and verify it is listing the directories you expect.
