nslookup gives one very little control over its output format. This is
just one of many ways in which it sucks. Since you have to change your
scripts anyway, why not dump nslookup altogether and use "dig" instead of
nslookup? If your scripts are written in Perl (or could be easily
converted to Perl), then even better yet would be to use the
Net::DNS Perl module.
