As you have seen from the discussion, it is more a basic Unix
programming question than a BIND issue.

In the short term, you now have enough Perl or shell scripts to solve
the problem :-)

In the long term, you may prefer to generate the zone files from a
database, rather than maintaining them in text form (which becomes
really painful when you have dozens of them).
