NAME
  du - estimate file space usage

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

DESCRIPTION
  Summarize disk usage of the set of FILEs, recursively for directories.

  Mandatory arguments to long options are mandatory for short options too.

    -0, --null
      end each output line with NUL, not 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 environment variables. Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is
  set).

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