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 _m_a_s_k
Ignore files and directories matching the specified _m_a_s_k.
--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 _d_e_p_t_h
Display an entry for all files and directories _d_e_p_t_h 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.

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.
