NAME
     du -- display disk usage statistics

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

DESCRIPTION
     The du utility displays the file system block usage for each file argu-
     ment and for each directory in the file hierarchy rooted in each direc-
     tory argument.  If no file is specified, the block usage of the hierarchy
     rooted in the current directory is displayed.  If the -k flag is speci-
     fied, the number of 1024-byte blocks used by the file is displayed, oth-
     erwise getbsize(3) is used to determine the preferred block size.	Par-
     tial numbers of blocks are rounded up.

     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.

     -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.
