Pop a new Current Directory and Disk off the Stack

Usage:  popd [-hvd-] [ n ]

   Pop an integer n directory paths from the top of the stack, making
   the top one remaining the new current directory and disk. The default
   for n is 1.

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

Options:

   -d   Discard just stack entry n, counting from 0 at the top, popping
        everything below it up one level.
   -s   Silent.  Don't print the resulting directory stack.
   -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.)
