Visudo(8) does all checking, locking and everything else you seem
to need. If you'll set VISUAL to some script that will perform all
automation you need. Like this:
-----
$ cat ed.sh
#!/bin/sh
echo "aghh lkjasd;flkja lkjsadf" > "$1"
$ cat ed1.sh
#!/bin/sh
echo "# comment" >> "$1"
exit
$ VISUAL=`pwd`/ed.sh visudo < /dev/null 2>&1 | grep -q "What now" && echo "Bad file"
Bad file
$ tail -2 /usr/local/etc/sudoers
# %users ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users localhost=/sbin/shutdown -h now
$ VISUAL=`pwd`/ed1.sh visudo < /dev/null 2>&1 | grep -q "What now" && echo "Bad file"
$
$ tail -2 /usr/local/etc/sudoers
# %users localhost=/sbin/shutdown -h now
# comment
