NAME
du - summarize disk usage
SYNOPSIS
du [-sarkx] [name . . .]
DESCRIPTION
The du command gives the number of sectors (512 bytes)
contained in all files and (recursively) directories within
each directory and file specified. The block count includes
the indirect blocks of the file. If no names are given, the
current directory is used.
A user with the appropriate privileges is able to display
information about all files and directories.
du has been multithreaded and uses the enhanced nftw [see
ftw(3C)] (walk a file tree) to increase its execution speed.
The optional arguments are as follows:
-s Give only the grand total (for each of the specified
names).
-a Generate an output line for each file.
-k Give block count in kilobytes.
-x Cause block count returned to not follow symbolic
links.
If neither -s or -a is specified, an output line is generated
for each directory only.
-r Generate messages about directories that cannot be read,
files that cannot be opened, and so on, rather than
being silent (the default).
A file with two or more links is only counted once.

NOTICES
If the -a option is not used, non-directories given as
arguments are not listed.

If there are links between files in different directories
where the directories are on separate branches of the file
system hierarchy, du counts the excess files more than once.
