       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.

       -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

              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

       -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

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

              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 environment 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  following:  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).
