I have searched for "dig return codes" and also looked at the man

Does `dig` have return codes that I can use to make some form of
automated tests?
foo=`dig NS example.com @ns2.example.com +short +time=2 +tries=1`
echo $foo

+time=2
+tries=1 ;;
global options: printcmd ;;
connection timed out; no servers could be reached
I do not know, nor would I want to have to know, all the possible
return strings I may get back. My needs are simple, I believe any
ANSWER of > 0 I would determine to be true, any timeout of any form
I would determine to be false.
Can anyone point me to docs on return codes, or is this going to
amount to string parsing? If it does, how much deviation on return
messages are there from the various dig versions that have been
released?
Thank you.
my dig (version DiG 9.6.1b1) returns RC 0 on both an answer and a
connection timeout, and would seem to require a string parsing for a
useful branch. F9 64 system.
Would you mind sharing with me how you tested that return value? I am
not seeing that bahavior at all, I get a true return for anything. I
have not been able to get false as of yet.
Thanks David.
