       du - estimate file space usage

       du [OPTION]... [FILE]...
       du [OPTION]... --files0-from=F

       Summarize disk usage of each FILE, recursively for directories.

       Mandatory  arguments  to	 long  options are mandatory for short options

       -a, --all
	      write counts for all files, not just directories

	      print apparent sizes,  rather  than  disk	 usage;	 although  the
	      apparent	size is usually smaller, it may be larger due to holes
	      in ('sparse') files, internal  fragmentation,  indirect  blocks,
	      and the like

       -B, --block-size=SIZE
	      use SIZE-byte blocks

       -b, --bytes
	      equivalent to '--apparent-size --block-size=1'

       -c, --total
	      produce a grand total

       -D, --dereference-args
	      dereference only symlinks that are listed on the command line

	      summarize	 disk usage of the NUL-terminated file names specified
	      in file F; If F is - then read names from standard input

       -H     equivalent to --dereference-args (-D)

       -h, --human-readable
	      print sizes in human readable format (e.g., 1K 234M 2G)

       --si   like -h, but use powers of 1000 not 1024

       -k     like --block-size=1K

       -l, --count-links
	      count sizes many times if hard linked

       -m     like --block-size=1M

       -L, --dereference
	      dereference all symbolic links

       -P, --no-dereference
	      don't follow any symbolic links (this is the default)

       -0, --null
	      end each output line with 0 byte rather than newline

       -S, --separate-dirs
	      do not include size of subdirectories

       -s, --summarize
	      display only a total for each argument

       -x, --one-file-system
	      skip directories on different file systems

       -X, --exclude-from=FILE
	      exclude files that match any pattern in FILE

	      exclude files that match PATTERN

	      print the total for a directory (or file, with --all) only if it
	      is   N   or  fewer  levels  below	 the  command  line  argument;
	      --max-depth=0 is the same as --summarize

       --time show time of the last modification of any file in the directory,
	      or any of its subdirectories

	      show  time  as WORD instead of modification time: atime, access,
	      use, ctime or status

	      show times using style STYLE: full-iso, long-iso,	 iso,  +FORMAT
	      FORMAT is interpreted like 'date'

       --help display this help and exit

	      output version information and exit

       Display	 values	 are  in  units	 of  the  first	 available  SIZE  from
       --block-size, and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE  environ-
       ment  variables.	  Otherwise,  units  default  to 1024 bytes (or 512 if
       POSIXLY_CORRECT is set).

       SIZE may be (or may be an integer optionally followed by) one  of  fol-
       lowing: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T,
       P, E, Z, Y.

       PATTERN is a shell pattern (not a regular expression).  The  pattern  ?
       matches	any  one  character, whereas * matches any string (composed of
       zero, one or multiple characters).  For example,	 *.o  will  match  any
       files whose names end in .o.  Therefore, the command

	      du --exclude='*.o'

       will skip all files and subdirectories ending in .o (including the file
       .o itself).
