= Bash Script=
Sample Bash script for extracting Domain Registration wiki page [[Domainreg]] and create a root zone file.
Set the following shell (environment) variables before running the script to produce a customized zone file header for that root zone that match your DNS server:
* RNS_FQDN - set this to the fully qualified domain name of your root name server.
** <pre> export RNS_FQDN=rns.cp.net</pre>
* RNS_IP - set this to the IP address of your root name server.
* DNS_ADMIN_EMAIL - set this to the email address of your DNS administrator
** <pre> export DNS_ADMIN_EMAIL=admin.cp.net</pre>
