You know, computers are really good at processing information through
things called "programs".
Off the top of my head:
sed -n 's/^zone "\(.*\)".*$/\1/p' < /etc/named.conf |
while read i
do
dig $i axfr | sed -n 's/^;; XFR size: \([0-9]*\) records.*/\1/p'
done |
perl -ne'$total += $_; END { print "$total\n" }'
(If I could assume the existence of the Net::DNS Perl module, this could
be much more elegant, just a single Perl program that performs all 3
parts of that pipeline above).
