NAME    [Toc]    [Back]

       df - report filesystem disk space usage

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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 containing
 a mounted filesystem, df shows the space available on that filesystem
 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

OPTIONS    [Toc]    [Back]

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

       -a, --all
	      include filesystems having 0 blocks

       --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, --kilobytes
	      like --block-size=1024

       -l, --local
	      limit listing to local filesystems

       -m, --megabytes
	      like --block-size=1048576

	      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

	      output version information and exit
