NAME
       df - report filesystem 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 filesystem	containing  each  file
       name  argument.	 If  no	file name is given, the	space available	on all
       currently mounted filesystems 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 filesystem, df shows the space available on that filesys-
       tem rather than on the filesystem containing the	device node (which  is
       always  the root	filesystem).  This version of df cannot	show the space
       available on unmounted filesystems, because on most  kinds  of  systems
       doing  so  requires  very  nonportable intimate knowledge of filesystem
       structures.

OPTIONS
       Show information	about the filesystem on	which each  FILE  resides,  or
       all filesystems by default.

       Mandatory  arguments  to	 long  options are mandatory for short options
       too.

       -a, --all
	      include filesystems having 0 blocks

       -B, --block-size=SIZE use SIZE-byte blocks

       -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 filesystems

       --no-sync
	      do not invoke sync before	getting	usage info (default)

       -P, --portability
	      use the POSIX output format

       --sync invoke sync before getting usage info

       -t, --type=TYPE
	      limit listing to filesystems of type TYPE

       -T, --print-type
	      print filesystem type

       -x, --exclude-type=TYPE
	      limit listing to filesystems not of type TYPE

       -v     (ignored)

       --help display this help	and exit

       --version
	      output version information and exit

       SIZE may	be (or may be an integer optionally followed by) one  of  fol-
       lowing: kB 1000,	K 1024,	MB 1,000,000, M	1,048,576, and so on for G, T,
       P, E, Z,	Y.
