dirs [ -c ] [ arg ... ]
dirs [ -lpv ]
       With no arguments, print the contents of the direc-
       tory stack.  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.

       -c     clear the directory stack.

       -l     print  directory  names  in  full instead of
              using of using ~ expressions.

       -p     print directory entries one per line.

       -v     number the directories  in  the  stack  when
              printing.
