Bash: Command line delete matching files and directories recursively

	# This searches recursively for all directories (-type d) in the hierarchy starting at "." (current directory), and finds those whose name is '.svn'; the list of the found directories is then fed to rm -rf for removal.

	find . -name '.svn' -type d \| xargs rm -rf

	# If you want to try it out, try

	find . -name '.svn' -type d \| xargs echo

	# This should provide you with a list of all the directories which would be recursively deleted.
