Skip over .svn directories when using the "find" command.
The "find" command can be annoying when used inside of a Subversion (or CVS) working directory. Obviously, you can combine this with other predicates and commands to create a more elaborate pipeline: $ find /var/svn -type f -not \( -name .svn -prune \) -print0 | xargs -0 md5sum Note: You can use my "dont-go-there.sh" script to wrap the "find" command and do this automatically at http://forwardlateral.com/blog/2006/02/27/dont-go-there/
