Might want to run that as "sudo" :)

Well, you could do, but why would you? Personally, I would open up a
console[0], use "su -" to become root and then use the command.

Either way (sudo or su) ... my point is that the results
of the "du" will be different if you running it as your
regular user or if running as the root user.

Which was why I initially said to be the root user when using it. That
way, there's not a long list of messages similar to:

du: cannot read directory `/var/cache/multipath': Permission denied

and the count isn't low because of the permission denied errors.

I'd like to add one other option for "du" ... the "-h" option,
which prints out the sizes in a human-readable format :)

I specifically didn't include that because, as Ulick points out, the
sort ordering won't work and gives the wrong results as shown here:

moray:~ # du / --max-depth=1 --one-file-system --exclude=/proc --exclude=/dev --exclude=/sys | sort -nr
