Shell Script to Dump all Domain Zone Records?

[beporter]

I've been searching the internet for some kind of script that will utilize dig or similar to dump ALL A, CNAME, MX, TXT, etc. records for a given domain. Is there any way to retrieve all of the records and IP addresses without knowing the actual subdomains to query? For example, if I just know "mydomain.com" is there any way to find the A and MX records (and the IPs they point to) for mail.mydomain.com programatically?

My goal is to automate a backup of all the records for a domain before performing a registrar transfer so I can recreate the records identically afterwards.

Does anyone know of an existing tool (or could provide a bit of guidance for a new shell script) that can manage this?

Thanks in advance!

What I'm looking to avoid is having to manually log into the registrar's website and write everything down by hand.

using the nslookup command (windows or UNIX) you can get this information.
here is a quick sample script for UNIX (nslookup-dmp.ksh)
usage will be nslookup-dmp.ksh {domain} i.e. yourname.com

#!/bin/ksh
/bin/echo "The Internet Address of $1..."
/bin/nslookup -q=A $1
/bin/echo "The canonical name for alias for $1..."
/bin/nslookup -q=CNAME $1
/bin/echo "The host CPU and OS Type..."
/bin/nslookup -q=HINFO $1
/bin/echo "The Mail Exchanger for $1..."
/bin/nslookup -q=MX $1
/bin/echo "The Statement of Authority for $1..."
/bin/nslookup -q=SOA $1
/bin/echo "The text information for $1..."
/bin/nslookup -q=TXT $1
/bin/echo "The Well Known Services for $1..."
/bin/nslookup -q=WKS $1
