sdu(1)

NAME
     sdu - Summarizes disk usage

SYNOPSIS
     sdu [-a] [-b] [-c] [-D] [-h] [--help] [-k] [-l] [-L] [-m]
     [-s] [--si] [-S] [--version] [-x] [file ...]

DESCRIPTION
     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.

OPTIONS
     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
               --bytes.

     -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
               specifying --total.

     -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
               --dereference-args.

     -h        Displays sizes in human-readable format.  For
               example, 1K, 234M, 2G.  Equivalent to specifying
               --human-readable.

     --help    Writes a usage message to standard output and
               exits successfully.

     -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
               --dereference.

     -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
               --one-file-system.

     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
               space character.
