NAME
       du - summarize disk usage

SYNOPSIS
       du [ -s ] [ -a ] [ name ... ]

DESCRIPTION
       _D_u  gives  the  number  of kilobytes contained in all files and, recur‐
       sively, directories within each specified directory or file  _n_a_m_e.   If
       _n_a_m_e is missing, ‘.’  is used.

       The  argument -s causes only the grand total to be given.  The argument
       -a causes an entry to be generated for each file.   Absence  of  either
       causes an entry to be generated for each directory only.

       A file which has two links to it is only counted once.

SEE ALSO
       df(1), quot(8)

BUGS
       Non-directories  given  as  arguments  (not  under  -a  option) are not
       listed.
       If there are too many distinct linked files, _d_u counts the excess files
       multiply.
