       df - report file system space usage

TOM T<?>T
       df [TUY_CH<?>N]<?> [T<?>P_TIN]<?>

MO T<?>
       This manual page documents the GNU version of df.  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.

       If an argument is the absolute file name of a device node containing a
       mounted file system, df shows the space available on that file system
       rather than on the file system containing the device node.  This
       version of 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.
