NAME
       df - report filesystem disk space usage

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

DESCRIPTION
       This manual page documents the GNU version of df.  df dis=AD
       plays 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 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=3DSIZE 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=3D1K

       -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=3DTYPE
	      limit listing to filesystems of type TYPE

       -T, --print-type
	      print filesystem type

       -x, --exclude-type=3DTYPE
	      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.

Thanks, to Lynn for the tip on how to clean up the output I captured.
With Linux I learn something new every day, usually every hour... :)
