           _D_u gives the number of blocks contained in all files and
           (recursively) directories within each directory and file
           specified by the _n_a_m_e_s argument.  If _n_a_m_e_s is missing, .... is
           used.  The block count is the number of 1024-byte blocks.
           The extra 4096-byte page taken by a multiple extent file is
           not included in the block count.

           The optional argument ----ssss causes only the grand total (for
           each of the specified _n_a_m_e_s) to be given.  The optional
           argument ----aaaa causes an entry to be generated for each file.
           Absence of either causes an entry to be generated for each
           directory only.

           _D_u is normally silent about directories that cannot be read,
           files that cannot be opened, etc.  The ----rrrr option will cause
           _d_u to generate messages in such instances.

           A file with two or more links is only counted once.

      BBBBUUUUGGGGSSSS
           If the ----aaaa option is not used, non-directories given as
           arguments are not listed.
           If there are too many distinct linked files, _d_u will count
           the excess files more than once.
