NAME
       df - report file system disk space usage
SYNOPSIS
       df [OPTION]... [FILE]...
DESCRIPTION
       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.
OPTIONS
       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 too.

       -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

       --direct
              show statistics for a file instead of mount point

       -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

       --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

       --total
              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

       --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).
       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).  Binary prefixes can be used, too: KiB=K, MiB=M,
       and so on.
      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).
