If you use visudo to edit the sudoers file, it will check the syntax
and not let you save a file that has errors.  It also makes sure
that the file owner and mode are correct and that no one else is
editing the file at the same time.

You can also use it to simply check the syntax of the sudoers file
by running:

    # visudo -c

If that does not show any errors then everything should be fine.
