Zone transfer changing the zone name

How would you define a script? Is a sequence of UNIX commands a
script?

You could of course do something on the order of (which can be given
all at once quite easily using the ; as a command separator):

dig zonename @server soa +norec > tmp
dig zonename @server axfr 2>&1 | egrep -vi '(soa|serial|retry|expiry|minimum)$' >> tmp
named-checkzone zonename tmp && ( mv tmp zonefile ; rndc reload zonename )

NOTE: This is untested, but you get the idea. Always try it manually
before applying it to a production box.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
