dirs [ -v ] [ arg ... ]
       With no arguments, print the contents of the direc
       tory  stack.  If the -v option is given, number the
       directories in the stack when  printing.   Directo
       ries  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.
