Thank you for the comments and suggestions!

I should used 'executable-find' for a local connection.  For a
tramp connection i don't know how to get the 'sh' location in the
remote host: i just kept '/bin/sh' for them.

     Don't assume /bin/sh as the 'sh' location in the local host

     * lisp/dired.el (dired-insert-directory): Use executable-find in
     a local host.
