       du - estimate file space usage

       du [OPTION]... [FILE]...

       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 FILEs that are symbolic links

       -H     like  --si,  but  also evokes a warning; will soon change to be
              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

       -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 filesystems

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

       --exclude=PATTERN 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

       --help display this help and exit

              output version information and exit

       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).
