dirs [ -v ] [ arg ... ]
       With  no  arguments,  print  the  contents  of  the
       directory stack.  If the -v option is given, number
       the  directories  in  the  stack   when   printing.
       Directories  are added to this stack with the pushd
       command, and removed with the cd or popd  commands.
       If  arguments  are  specified,  load  them onto the
       directory stack, replacing anything that was there,
       and push the current directory onto the stack.
