RedHat 9 (Linux i386) - man page for df (redhat section 1)

DF(1)					       FSF					    DF(1)

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 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 can-
       not 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  following:  kB  1000,	K
       1024, MB 1,000,000, M 1,048,576, and so on for G, T, P, E, Z, Y.
