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  com-
       mand, and removed with the cd or popd commands.  If
       arguments are specified, load them onto the  direc-
       tory  stack, replacing anything that was there, and
       push the current directory onto the stack.
