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

NAME
     du - display disk usage statistics

SYNOPSIS
     du [-H | -L | -P] [-a | -s | -d depth] [-c] [-h | -k | -m] [-n] [-x]
        [-I mask] [file ...]

DESCRIPTION
     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:

     -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
             followed.

     -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)

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

     -c      Display a grand total.

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

     -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.

     Files having multiple hard links are counted (and displayed) a single
     time per du execution.

ENVIRONMENT
     BLOCKSIZE  If the environment variable BLOCKSIZE is set, and the -k
                option is not specified, the block counts will be displayed in
                units of that size block.  If BLOCKSIZE is not set, and the -k
                option is not specified, the block counts will be displayed in
                512-byte blocks.
