【问题描述】：
我的服务器上有一个大型文本文件，其中包含我需要获取其联系信息的域列表。这是我在 stackoverflow.com 上运行 whois 时显示的一个示例：
root@server [~]# whois stackoverflow.com
[Querying whois.verisign-grs.com]
[Redirected to whois.name.com]
[Querying whois.name.com]
[whois.name.com]

我需要做的是从每个查询中提取某些信息。问题是我不明白如何仅从每个域 whois 中提取联系电子邮件，因为每个 whois 结果因注册商而异。
例如，我希望它是这样工作的：
通过命令行，我的服务器应该检查每个域名的 whois 信息，并将所有结果导出到一个新的文本文件，该文件只包含域名所有者的电子邮件地址。包含所有域的文件的名称是 domain.txt，如果可能的话，我希望将新文件命名为 new.txt。
对此的任何帮助将不胜感激。提前致谢！
