and according to RTFM you should use 'visudo' to edit the sudoers file.

man visudo

NAME
       visudo - edit the sudoers file

SYNOPSIS
       visudo [ -c ] [ -f sudoers ] [ -q ] [ -s ] [ -V ]

DESCRIPTION
       visudo edits the sudoers file in a safe fashion, analogous to
       vipw(8).visudo locks the sudoers file against multiple
       simultaneous edits, provides basic sanity checks, and checks for
       parse errors.  If the sudoers file is currently being edited you
       will receive a message to try again later.
