It seems to me that the simplest way would be like this:

 ls(Dir) ->
    case file:list_dir(Dir) of
{ok, Entries} ->
    ls_print(sort(Entries));
{error, enotdir} ->
    ls_print([Dir]);
{error, Error} ->
    format(file:format_error(Error))
    end.

(and deleting the ls_file/2 function.)

Do you seen any problem with that method?
