如何限制 whois 命令的输出？

Question

如何从 PTR whois 查找中仅获取所有者/组织名称？我不需要所有其他的东西，只需要关于所有权的部分（在这种情况下是谷歌）。

Edit /usr/bin/whois 74.125.236.52 或任何 ip get OrgName

如果您想要IP 地址所有者的域名（而不是公司名称），也许使用dig -x?

$ dig +short -x 74.125.236.52
maa03s04-in-f20.1e100.net.

如果您只想要输出中的“OrgName:”行whois，您可以使用grep以下命令将其挑出：

$ whois 74.125.236.52 | grep OrgName
OrgName:        Google Inc.

正如其他地方所提到的，这可能并不总是有效，因为没有在任何地方指定输出格式。
