DU(1)                                                       DU(1)

     NAME
          du - summarize disk usage

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

     DESCRIPTION
          Du gives the number of kilobytes (kilo=1024) allocated to
          data blocks of named files and of named directories includ-
          ing (recursively) their contents.  If name is missing, `.'
          is used.

          Option -s causes only the grand total to be given.  Option
          -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 counted only once.

     SEE ALSO
          df(1), quot(8)

     BUGS
          In the absence of option -a non-directories given as argu-
          ments are not listed.
          If there are too many distinct linked files, du counts the
          excess files multiply.
          Unwritten holes in files count as if real data were present,
          and indirect blocks are not counted.
