DU(1)                                BSD                                 DU(1)



NAME
     du - summarize disk usage

SYNOPSIS
     du [ -a ] [ -s ] [ names ]

DESCRIPTION
     du gives the number of kilobytes contained in all files and, recursively,
     directories within each directory specified by names.  If you don't
     specify a names argument, du prints information about the current
     directory, " ." by default.  A file that has two links to it is only
     counted once.

OPTIONS
     -a        Generate an entry for each file.

     -s        Print only the grand total of kilobytes for each of the
               specified names.

     Absence of either the -a option or the -s option causes an entry to be
     generated for each directory only.

BUGS
     If you don't use the -a option, du does not list nondirectories given as
     arguments.

     If too many distinct linked files exist, du counts the excess files more
     than once.
