Remove all .DS_Store files

.DS_Store  files aren't much of a problem to your Mac, these small files provide information about how you want to see the directory laid out, the position of icons within the folder. However, if they disturb your chi you can remove them recursively from /  using the following command:

sudo find / -name ".DS_Store" -depth -exec rm {} \;

These files will of course be regenerated whenever you enter a directory without one via Finder.
