Thanks Ed, this functionality seems to be counter intuitive to me. Given
that du shows space used in sub-directories, it seems to me the only
useful output is du without any parameters.
'du' with no parameters recursively lists all the subdirectories and
their sizes, along with the grand total. When applied to my home
directory, I get over 30,000 lines of output. That's almost never what
I want. My usual call is 'du -hs'.

Thanks Patrick, taking this a step further, it seems to me that the only
parameter for du that, to me, provides the correct file size is -b as
shown below. I am listing my Desktop directory via ll, du -hs and du
-bhs. Just further to this is it a bug with du that the -a parameter
which is supposed to list all files not just directories, does not list
files prefixed with a '.'?:
