du(1M)                  (BSD Compatibility Package)                  du(1M)


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

   SYNOPSIS
         /usr/ucb/du [ -F ufs ]

         /usr/ucb/du [ -F ufs ] [ -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 directory 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.
