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

  -a, --all             include dummy file systems

  -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.

      --total           produce a grand total

  -h, --human-readable  print sizes in human readable format (e.g., 1K 234M 2G)

  -H, --si              likewise, but use powers of 1000 not 1024

  -i, --inodes          list inode information instead of block usage

  -k                    like --block-size=1K

  -l, --local           limit listing to local file systems

      --no-sync         do not invoke sync before getting usage info (default)

      --output[=FIELD_LIST]  use the output format defined by FIELD_LIST,

                               or print all fields if FIELD_LIST is omitted.

  -P, --portability     use the POSIX output format

      --sync            invoke sync before getting usage info

  -t, --type=TYPE       limit listing to file systems of type TYPE

  -T, --print-type      print file system type

  -x, --exclude-type=TYPE   limit listing to file systems not of type TYPE

  -v                    (ignored)

      --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 DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment 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, ... (powers of 1000).

FIELD_LIST is a comma-separated list of columns to be included.  Valid

field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent',

'size', 'used', 'avail', 'pcent' and 'target' (see info page).

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)

  -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   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 STYLE:

                          full-iso, long-iso, iso, +FORMAT

                          FORMAT is interpreted like '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).
