This documentation is no longer being maintained and may be
inaccurate or incomplete. The Texinfo documentation is now
the authoritative source.
This manual page documents the GNU version of dddduuuu. dddduuuu
displays the amount of disk space used by each argument and
for each subdirectory of directory arguments. The space is
measured in 1K blocks by default, unless the environment
variable POSIXLY_CORRECT is set, in which case 512-byte
blocks are used.

-_a, --_a_l_l
Display counts for all files, not just directories.
-_b, --_b_y_t_e_s
Print sizes in bytes.
-_c, --_t_o_t_a_l
Write a grand total of all of the arguments after all
arguments have been processed. This can be used to
find out the disk usage of a directory, with some files
excluded.
-_k, --_k_i_l_o_b_y_t_e_s
Print sizes in kilobytes. This overrides the
environment variable POSIXLY_CORRECT.
-_l, --_c_o_u_n_t-_l_i_n_k_s
Count the size of all files, even if they have appeared
already in another hard link.
-_s, --_s_u_m_m_a_r_i_z_e
Display only a total for each argument.
-_x, --_o_n_e-_f_i_l_e-_s_y_s_t_e_m
Skip directories that are on different filesystems from
the one that the argument being processed is on.
-_D, --_d_e_r_e_f_e_r_e_n_c_e-_a_r_g_s
Dereference symbolic links that are command line
arguments. Does not affect other symbolic links. This

is helpful for finding out the disk usage of
directories like /usr/tmp where they are symbolic
links.
-_L, --_d_e_r_e_f_e_r_e_n_c_e
Dereference symbolic links (show the disk space used by
the file or directory that the link points to instead
of the space used by the link).
-_S, --_s_e_p_a_r_a_t_e-_d_i_r_s
Count the size of each directory separately, not
including the sizes of subdirectories.
--_h_e_l_p
Print a usage message on standard output and exit
successfully.
--_v_e_r_s_i_o_n
Print version information on standard output then exit
successfully.

On BSD systems, dddduuuu reports sizes that are half the correct
values for files that are NFS-mounted from HP-UX systems.
On HP-UX systems, it reports sizes that are twice the
correct values for files that are NFS-mounted from BSD
systems. This is due to a flaw in HP-UX; it also affects
the HP-UX dddduuuu program.
