       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

       -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 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

              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 subdirectories

              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

       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).
