Question

我的服务器上有一个大文本文件，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时出现的一个例子：

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.

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从每个域中提取联系人电子邮件，因为每个whois结果因注册商而异。

例如，这就是我喜欢它的工作方式：

通过命令行，我的服务器应检查每个域名的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domains.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。提前谢谢！

Answer 1

你首先要做的事情是搜索whois on cpan，然后选择不那么过时，最有争议和最相关的事情。

Answer 2

不一定是Perl，但由于您是在命令行（可能是linux）上执行此操作，因此您可以使用shell脚本执行以下操作。

cat domain.txt | while read line
do
echo "$line - `whois $line | grep \"@\"`" >> new.txt
done

如果您的domain.txt文件如下所示：

stackoverflow.com

然后你的new.txt看起来像：

stackoverflow.com - sysadmin-team@stackoverflow.com
stackoverflow.com - sysadmin-team@stackoverflow.com
stackoverflow.com - sysadmin-team@stackoverflow.com
stackoverflow.com - sysadmin-team@stackoverflow.com

您可以添加一些'sort'和'uniq'命令来清理重复的值。如有必要，请告诉我，我会详细说明。

如何使用命令行获取whois信息？
