    Display the list of currently remembered directories.  Directories
    find their way onto the list with the `pushd' command; you can get
    back up through the list with the `popd' command.
    
    The -l flag specifies that `dirs' should not print shorthand versions
    of directories which are relative to your home directory.  This means
    that `~/bin' might be displayed as `/homes/bfox/bin'.  The -v flag
    causes `dirs' to print the directory stack with one entry per line,
    prepending the directory name with its position in the stack.  The -p
    flag does the same thing, but the stack position is not prepended.
    The -c flag clears the directory stack by deleting all of the elements.

    -N	displays the Nth entry counting from the right of the list shown by
    	dirs when invoked without options, starting with zero.
