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

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

       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).

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

--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.

              [possiblevalues:  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
