大家都知道查看域名的詳細信息，都是跑去whois服務器去查詢，如 http://whois.chinaz.com

其實在Linux下直接有一個whois的命令，不過需要安裝jwhois才可以，以CentOS為例：

安裝：

[root@centos ~]# yum install jwhois -y

使用：

root@centos ~]# whois le23.com[Querying whois.verisign-grs.com][Redirected to whois.dns.com.cn][Querying whois.dns.com.cn][whois.dns.com.cn] Domain Name.......... le23.com  Creation Date........ 2010-05-14 01:37:32  Registration Date.... 2010-05-14 01:37:32  Expiry Date.......... 2012-05-14 01:37:32  Organisation Name....
