NAME
     dduu - display disk usage statistics

SYNOPSIS
     dduu [-HH | -LL | -PP] [-II mask] [-aa | -ss | -dd depth] [-cc] [-hh | -kk] [-xx]
        [file ...]

DESCRIPTION
     The dduu utility displays the file system block usage for each file argu-
     ment and for each directory in the file hierarchy rooted in each direc-
     tory argument.  If no file is specified, the block usage of the hierarchy
     rooted in the current directory is displayed.  If the -kk flag is speci-
     fied, the number of 1024-byte blocks used by the file is displayed, oth-
     erwise getbsize(3) is used to determine the preferred block size.  Par-
     tial numbers of blocks are rounded up.

     The options are as follows:

     -HH      Symbolic links on the command line are followed, symbolic links
             in file hierarchies are not followed.

     -LL      Symbolic links on the command line and in file hierarchies are
             followed.

     -II mask
             Ignore files and directories matching the specified mask.

     -PP      No symbolic links are followed.  This is the default.

     -aa      Display an entry for each file in a file hierarchy.

     -hh      "Human-readable" output.  Use unit suffixes: Byte, Kilobyte,
             Megabyte, Gigabyte, Terabyte and Petabyte

     -rr      Generate messages about directories that cannot be read, files
             that cannot be opened, and so on.  This is the default case.
             This option exists solely for conformance with X/Open Portability
             Guide Issue 4 (``XPG4'').

     -ss      Display an entry for each specified file.  (Equivalent to -dd 0)

     -dd depth
             Display an entry for all files and directories depth directories
             deep.

     -cc      Display a grand total.

     -kk      Display block counts in 1024-byte (1-Kbyte) blocks.

     -xx      File system mount points are not traversed.

     The dduu utility counts the storage used by symbolic links and not the
     files they reference unless the -HH or -LL option is specified.  If either
     the -HH or -LL options are specified, storage used by any symbolic links
     which are followed is not counted or displayed.

     Files having multiple hard links are counted (and displayed) a single
     time per dduu execution.

ENVIRONMENT
     BLOCKSIZE  If the environment variable BLOCKSIZE is set, and the -kk
                option is not specified, the block counts will be displayed in
                units of that size block.  If BLOCKSIZE is not set, and the -kk
                option is not specified, the block counts will be displayed in
                512-byte blocks.
