NAME
       du - estimate file space usage

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

DESCRIPTION
       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

       --apparent-size
	      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  levels  below	 the  command  line  argument;
	      --max-depth=0 is the same as --summarize

       --files0-from=F
	      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)

       --inodes
	      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 negative

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

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

       --time-style=STYLE
	      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=PATTERN
	      exclude files that match PATTERN

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

       --help display this help and exit

       --version
	      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 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, ... (pow-
       ers of 1000).

PATTERNS
       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).
