NAME
     du - display the number of disk blocks used per directory or
     file

SYNOPSIS
     /usr/ucb/du [ -a ] [ -s ] [ filename ]

DESCRIPTION
     du gives the number of kilobytes contained in all files and,
     recursively,  directories within each specified directory or
     file filename.  If filename is missing,  `.'   (the  current
     directory)  is  used.  A file which has multiple links to it
     is only counted once.

OPTIONS
     -a   Generate an entry for each file.

     -s   Only display the grand total for each of the  specified
          filenames.   Entries are generated only for each direc-
          tory in the absence of options.

EXAMPLE
     Here is an example of using du in a directory.  We used  the
     pwd(1)  command  to  identify the directory, then used du to
     show the usage of all the subdirectories in that  directory.
     The  grand  total for the directory is the last entry in the
     display:
          % pwd
          /usr/ralph/misc
          % du
          5    ./jokes
          33   ./squash
          44   ./tech.papers/lpr.document
          217  ./tech.papers/new.manager
          401  ./tech.papers
          144  ./memos
          80   ./letters
          388  ./window
          93   ./messages
          15   ./useful.news
          1211 .
          %

NOTES
     Filename arguments that are not directory names are ignored,
     unless  you  use -a .  If there are too many distinct linked
     files, du will count the excess files more than once.
