df - report file system disk space usage


   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
   containing  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
   systems, because on most  kinds  of  systems  doing  so  requires  very
   nonportable 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 pseudo, duplicate, inaccessible 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

   -h, --human-readable
          print sizes in powers of 1024 (e.g., 1023M)

   -H, --si
          print sizes in powers of 1000 (e.g., 1.1G)

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

   -k     like --block-size=1K

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

          do not invoke sync before getting usage info (default)

          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

          elide  all entries insignificant to available space, and produce
          a grand total

   -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

          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).

   The  SIZE  argument  is  an  integer and optional unit (example: 10K is
   10*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', 'file' and 'target' (see
   info page).
