I have a large text file on my server that has a list of domains in it that I need to get the contact information for. Here's an example of that's showing up for me when I run whois on stackoverflow.com:

```
root@server [~]# whois stackoverflow.com
[Querying whois.verisign-grs.com]
[Redirected to whois.name.com]
[Querying whois.name.com]
[whois.name.com]

      On a first name basis with the rest of the world.

What I need to do is extract certain information from each query. The problem is that I don't understand how to extract just the contact emails from each domain whois because each whois result is different depending on the registrar.

For example, this is how I'd like it to work:

Through command line my server should check the whois information for each domain name and export all the results to a new text file that would just contain the email addresses for the owners of the domain name. The name of the file containing all the domains is domains.txt and I would like the new file to be named new.txt if possible.

Any help with this would be greatly appreciated. Thanks in advance!
