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

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
; <<>> DiG 9.4.3-P1 <<>> NS example.com @ns2.example.com +short
+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.
