       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 too.

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

       -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
	      scale  sizes  by	SIZE  before  printing them; e.g., '-BM' prints sizes in units of
	      1,048,576 bytes; see SIZE format below

       -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

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

	      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)

	      list inode usage information instead of block usage

       -k     like --block-size=1K

       -L, --dereference
	      dereference all symbolic links

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

       -m     like --block-size=1M

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

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

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

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

       -t, --threshold=SIZE
	      exclude entries smaller than SIZE if positive, or entries greater than SIZE if neg-

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

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

	      show times using STYLE, which can be: full-iso, long-iso, iso, or  +FORMAT;  FORMAT
	      is interpreted like in 'date'

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

	      exclude files that match PATTERN

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

       --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 environment variables.  Otherwise,  units  default
       to 1024 bytes (or 512 if POSIXLY_CORRECT is set).

       SIZE  is  an integer and optional unit (example: 10M is 10*1024*1024).  Units are K, M, G,
       T, P, E, Z, Y (powers of 1024) or KB, MB, ... (powers of 1000).

       bugs to <http://translationproject.org/team/>

       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).
