      [file ...] | 
du utility displays the file system 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-L-P-a-c-d-g-g flag is specified, the number displayed
      is the number of gigabyte (1024*1024*1024 bytes) blocks.-h-h flag is specified, the numbers will be
      displayed in "human-readable" format. Use unit suffixes: B
      (Byte), K (Kilobyte), M (Megabyte), G (Gigabyte), T (Terabyte) and P
      (Petabyte).-i-kdu displays the number of blocks as
      returned by the stat(2) system
      call, i.e. 512-byte blocks. If the -k flag is
      specified, the number displayed is the number of kilobyte (1024 bytes)
      blocks. Partial numbers of blocks are rounded up.-m-m flag is specified, the number displayed
      is the number of megabyte (1024*1024 bytes) blocks.-nUF_NODUMP) set.-r-s-xdu 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. The -H,
    -L and -P options override
    each other and the command's actions are determined by the last one
    specified.
Files having multiple hard links are counted (and displayed) a
    single time per du execution.
BLOCKSIZEBLOCKSIZE is set, and
      the -g, -h,
      -k, and -m options are not
      specified, the block counts will be displayed in units of that size
    block.du utility exits 0 on success,
  and >0 if an error occurs.
