DU(1)               UNIX Programmer's Manual                DU(1)

NAME
     du  -  summarize disk usage

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

DESCRIPTION
     _D_u gives the number of 1024-byte blocks contained in all
     files and (recursively) directories within each specified
     directory or file _n_a_m_e.  If _n_a_m_e is missing, `.' is used.
     Options are:

     -a   Generate an entry for each file.

     -s   Give a grand total only.

     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.

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.
