I am a commandline geek from way back, so you're welcome.
My brother actually had a Dilbert from years ago that he gave me where
Dilbert runs into a guy with a long beard and suspenders and says "Hey,
you're one of those Unix geeks, aren't you?"
I wish I could get that on a T-Shirt!
Anyway, the sourcing idea is definitely a good one. I'm not usually
working with such easy source material (I do a lot of stuff where I'm
pulling information off a website, etc)

yes, that's right

Ah, ok. When you are done with the "elif" (short for "else if" BTW)
you may use an "ELSE" that covers everything else.
Since you've already matched for YES and NO then all you need is to add
in a catch-all (NOTE: there is no "THEN" when dealing with ELSE. only
IF or ELIF takes a THEN
if [ "$grog_firewall_enable" = "YES" ]
then
echo "Firewall enabled."
elif [ "$grog_firewall_enable" = "NO" ]
then
echo "Firewall disabled."
else
echo "Syntax error in /etc/rc.conf file. grog_firewall_enable must be
YES or NO"
exit 1
fi
the 'exit 1' is optional. If you include it, the script will end right
there, which may or may not be ideal.
