+[NAME]
+df \- report file system space usage
+[DESCRIPTION]
+This manual page
+documents the GNU version of
+.BR df .
+.B df
+displays the amount of 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.
+Space is shown in 1K blocks by default, unless the environment
+variable POSIXLY_CORRECT is set, in which case 512-byte blocks are
+used.
+.PP
+If an argument is the absolute file name of a device node containing a
+mounted file system,
+.B df
+shows the space available on that file system rather than on the
+file system containing the device node.  This version of
+.B df
+cannot show the space available on unmounted file systems, because on
+most kinds of systems doing so requires non-portable intimate
+knowledge of file system structures.
