DNS BIND 9 Primary named.conf reformat/convert to Secondary server script

[JPrine]

This script will create a file named "named.conf.gypsy" that is an
exact copy of named.conf, but reformatted to the way a secondary DNS
server needs it. How you get it to the secondary is up to you, i use
crontabs to scp it over every night. Used in combination with "rndc
reload" and "rndc flush" this should eliminate the need for any DNS
maintenance on a secondary server. Please let me know how it
goes...Enjoy!

Here she blows...

#! /bin/sh
cd /etc/

#write the header to a file (first 22 lines)

# just modify the zone file lines, the first 22 lines do not need to
be changed
