du - Windows command-line utility to displays disk usage
SYNOPSIS
du [-a | -s] [-k] [-x] [-r] [file...]
DESCRIPTION
The du(1w) utility displays the number of blocks for a
specified file. If the file operand is a directory,
du displays the number of blocks occupied by the files in
the directory, and recursively for all directories within the
specified directory.
When du cannot access files or directories, it reports an
error (if the -r option is specified), and the
final exit status is affected. By default, file size is written in
512-byte units, rounded up to the next 512-byte unit.
The du utility supports the following options:
No option
Reports the size of the directory, and recursively for all
directories within the specified file.
-a
In addition to the default output, the -a
option reports the size of each file, including the files in the
subdirectories of the specified file. Regardless of the
presence of the -a option, nondirectories given
as file operands are always listed.
-k
Writes the file size in 1,024-byte units, rather than the
default 512-byte units.
-r
Generates messages about files and directories that cannot be
accessed.
-s
Reports the total sum for each of the specified files instead
of the default output.
-x
Evaluates only those files that have the same device as
file.
