DU(1)                   FreeBSD General Commands Manual                  DU(1)

     du - display disk usage statistics

     du [-A] [-H | -L | -P] [-a | -s | -d depth | -t threshold] [-c] [-l]
        [-h | -k | -m | -B blocksize] [-n] [-x] [-I mask] [file ...]

     The du utility displays the file system block usage for each file
     argument and for each directory in the file hierarchy rooted in each
     directory argument.  If no file is specified, the block usage of the
     hierarchy rooted in the current directory is displayed.

     The options are as follows:

     -A      Display the apparent size instead of the disk usage.  This can be
             helpful when operating on compressed volumes or sparse files.

     -B blocksize
             Calculate block counts in blocksize byte blocks.  This is
             different from the -k, -m options or setting BLOCKSIZE and gives
             an estimate of how much space the examined file hierachy would
             require on a filesystem with the given blocksize.  Unless in -A
             mode, blocksize is rounded up to the next multiple of 512.

     -H      Symbolic links on the command line are followed, symbolic links
             in file hierarchies are not followed.

     -L      Symbolic links on the command line and in file hierarchies are

     -I mask
             Ignore files and directories matching the specified mask.

     -P      No symbolic links are followed.  This is the default.

     -a      Display an entry for each file in a file hierarchy.

     -h      "Human-readable" output.  Use unit suffixes: Byte, Kilobyte,
             Megabyte, Gigabyte, Terabyte and Petabyte.

     -r      Generate messages about directories that cannot be read, files
             that cannot be opened, and so on.  This is the default case.
             This option exists solely for conformance with X/Open Portability
             Guide Issue 4 (``XPG4'').

     -s      Display an entry for each specified file.  (Equivalent to -d 0)

     -t threshold
             Display only entries for which size exceeds threshold.  If
             threshold is negative, display only entries for which size is
             less than the absolute value of threshold.

     -d depth
             Display an entry for all files and directories depth directories

     -c      Display a grand total.

     -k      Display block counts in 1024-byte (1-Kbyte) blocks.

     -l      If a file has multiple hard links, count its size many times.
             The default behavior of du is to count files with multiple hard
             links only once.  When the -l option is specified, the hard link
             checks are disabled, and these files are counted (and displayed)
             as many times as they are found.

     -m      Display block counts in 1048576-byte (1-Mbyte) blocks.

     -n      Ignore files and directories with user ``nodump'' flag
             (UF_NODUMP) set.

     -x      File system mount points are not traversed.

     The du utility counts the storage used by symbolic links and not the
     files they reference unless the -H or -L option is specified.  If either
     the -H or -L options are specified, storage used by any symbolic links
     which are followed is not counted or displayed.

     BLOCKSIZE  If the environment variable BLOCKSIZE is set, and the -k, -m
                or -h options are not specified, the block counts will be
                displayed in units of that block size.  If BLOCKSIZE is not
                set, and the -k, -m or -h options are not specified, the block
                counts will be displayed in 512-byte blocks.

     df(1), chflags(2), fts(3), symlink(7), quot(8)

     A du command appeared in Version 1 AT&T UNIX.
