df [OPTION]... [FILE]...


       This  manual  page  documents  the  GNU version of df.  df displays the
       amount of disk space available on the file system containing each  file
       name  argument.   If  no file name is given, the space available on all
       currently mounted file systems is shown.  Disk space  is  shown  in  1K
       blocks  by  default, unless the environment variable POSIXLY_CORRECT is
       set, in which case 512-byte blocks are used.

       If an argument is the absolute file name of a disk device node contain-
       ing  a  mounted  file system, df shows the space available on that file
       system rather than on the file system containing the device node.  This
       version  of  df  cannot show the space available on unmounted file sys-
       tems, because on most kinds of systems  doing  so  requires  very  non-
       portable intimate knowledge of file system structures.


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

       Mandatory arguments to long options are  mandatory  for  short  options

       -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

              show statistics for a file instead of mount point

              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

       -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

              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  environ-
       ment  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, ... (pow-
       ers 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', 'file'  and  'target'  (see
       info page).
