List the Current Directory Stack

Usage:  dirs [-h-]

   Show the list of fully-qualified directory pathnames on the current
   directory stack, highlighting the current disk:directory pair.

   Hamilton C shell maintains a stack representing the current directory
   and any previous current directories the user has saved there.

   (See also the cd, pushd, popd and rotd commands.)

Options:

   -h   Help.  (This screen.)
   --   End of options.

(The slash, "/", may be used instead of a minus to introduce
options.  To specify a different set of characters to introduce
options, use the SWITCHCHARS environmental variable.)
