sdu - Summarizes disk usage
sdu [-a] [-b] [-c] [-D] [-h] [--help] [-k] [-l] [-L] [-m]
[-s] [--si] [-S] [--version] [-x] [file ...]
This man page describes the GNU version of the du(1) command
as enhanced by Oracle Corporation for the SAM-QFS file system.
The sdu command displays the amount of disk space used by
each file argument. If file is a directory, the command
returns disk space information for each subdirectory of
file. If file is a removable media file, the command
returns 0 for the size of that file.
By default, the space is returned in 1K blocks, but if the
POSIXLY_CORRECT environment variable is set, 512-byte blocks
are reported. The sdu command displays actual disk blocks
for online SAM-QFS files. It also displays an estimate of
disk blocks (based on file size) for offline SAM-QFS files.
To get actual disk block usage for both online and offline
files, use the du(1) command.
This command accepts the following options:
-a Displays counts for all files, not just
directories. Equivalent to specifying --all.
-b Displays sizes in bytes. Equivalent to specifying
-c Writes a grand total of all of the arguments after
all arguments have been processed. This can be
used to determine the disk usage of a directory
with some files excluded. Equivalent to
-D Dereferences symbolic links that are command line
arguments. Does not affect other symbolic links.
This is helpful for determining the disk usage of
directories like /usr/tmp if they are symbolic
links. Equivalent to specifying
-h Displays sizes in human-readable format. For
example, 1K, 234M, 2G. Equivalent to specifying
--help Writes a usage message to standard output and
-k Displays sizes in kilobytes. This overrides the
environment variable POSIXLY_CORRECT. Equivalent
to specifying --kilobytes.
-l Counts the size of all files, even if they have
appeared already in another hard link. Equivalent
to specifying --count-links.
-L Dereferences symbolic links. That is, the command
shows the disk space used by the file or directory
that the link points to instead of the space used
by the link. Equivalent to specifying
-m Uses 1024-kilobyte blocks, not 512, regardless of
the POSIXLY_CORRECT environment variable setting.
Equivalent to specifying --megabytes.
-s Displays only a total for each argument.
Equivalent to specifying --summarize.
--si Like -h, but size is displayed in base 10 units.
-S Counts the size of each directory separately, not
including the sizes of subdirectories. Equivalent
to specifying --separate-dirs.
--version Displays version information on standard output
then exits successfully.
-x Skips directories that are on different file
systems from the one that the file being processed
is on. Equivalent to specifying
file Specifies the file or the path to the file being
analyzed. The size is written. If no file is
specified, the current directory is used. If more
than one file is specified, separate each with a
