       df  [--help]  [-a|--all]  [-B|--block-size]  [--total]   [-h|--human-readable]   [-H|--si]
       [-i|--inodes]  [-k  ]  [-l|--local]  [--no-sync]  [--output]  [-P|--portability]  [--sync]

DESCRIPTION

       Show information about the file system on which each FILE resides, or all file systems  by
       default.

OPTIONS

       --help Print help information.

       -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

       --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 [default: source,size,used,avail,pcent,target]
              use the output format defined by FIELD_LIST, or print all fields if  FIELD_LIST  is
              omitted.

              [possible values: source, fstype, itotal, iused, iavail, ipcent, size, used, avail,
              pcent, file, target]

       -P, --portability
              use the POSIX output format

       --sync invoke sync before getting usage info (non-windows only)

       -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, --version
              Print version

       [paths]

EXTRA

       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).
