NAME
     du	-- display disk	usage statistics

SYNOPSIS
     du	[-P | -H | -L] [-a | -s	| -d depth] [-c] [-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:

     -P	     No	symbolic links are followed. (default)

     -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.

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

     -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	     Filesystem	mount points are not traversed.

     Du	counts the storage used	by symbolic links and not the files they ref-
     erence 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 fol-
     lowed 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 op-
		tion is	not specified, the block counts	will be	displayed in
		1024-byte blocks. If BLOCKSIZE is not set, and the -k option
		is not specified, the block counts will	be displayed in
		512-byte blocks.
