Automatically Adding or Removing Files

Especially useful when, for example, versioning /etc/:

Files to remove:
svn stat -q | grep '^!'
svn stat -q | grep '^!' | sed -e 's/^!\s*//' | xargs | svn rm
Files to add:
svn stat | grep '^?'
svn stat -q | grep '^?' | sed -e 's/^?\s*//' | xargs | svn rm
find . -name 'dpkg-old' -exec rm -i  ;
