Cross-Platform Millionaire Lookup Script

I need a reliable way to confirm whether a given high-net-worth individual is associated with my freemasonry verification service. For every millionaire in the list I supply—or that you source—you will provide both a verifiable street or registered business address and an official email address. The end goal is to feed those two data points into a DNS-based lookup flow similar to:

Linux / Unix: `dig txt firstname.lastname.becomefreemason.com`
Windows: `nslookup -q=txt firstname.lastname.becomefreemason.com`

Because I will be running checks from machines on both platforms, the script you deliver must execute cleanly under Bash and PowerShell without any manual tweaks. An auto-detect of the OS with the right call to `dig` or `nslookup` is ideal.

Deliverables:
• A CSV or SQLite dataset containing each millionaire’s full name, address, and official email.
• A cross-platform script (Bash + PowerShell, or a single portable language such as Python) that reads the dataset, builds the hostname as shown above, and performs the TXT lookup automatically, returning the result in the console.
• Clear setup instructions and a short README explaining dependencies and how to add new names.

Acceptance criteria: the script must run unmodified on current Windows 10/11 and any recent Linux distribution, return the TXT record for at least five sample names I provide, and exit with a non-zero code if the record is missing.

Gather a list of most milloners around the world with thier address and/or official email to verfiy thier lookup quicky of freemasonary system on any computer connected to the internet, something like this:

Linux/Unix: dig txt andy.swietek.becomefreemason.com
Microsoft Windows: nslookup -q=txt andy.swietek.becomefreemason.com
