[NTLUG:Discuss] Script for domain validation

[Steve Southwell]

I've just about got a script working, and what I want it to do is simply 
validate that a given domain exists. (It's part of an email address 
validation routine)

I'm just about brain dead this afternoon - can anyone tell my why this 
doesn't work, and perhaps suggest a fix:

host $1 | grep " has address " &> /dev/null || echo "Bad"; exit 1
echo "Good"; exit 0

what happens is that it correctly handles the "Bad" case, but doesn't 
handle the good case.
