我已经在使用你的这个脚本了，刚好可以解决动态IP的问题。
然后执行命令后有个提示说，第13行 dig:未找到命令。

虽然没啥影响，但是强迫症看到提示，就想解决这个问题，请问这是什么原因导致的？

来自新手的疑问。

哦，你需要安装 dig 这个工具，ubuntu 的话应该是 $ sudo apt-get install dnsutils 就可以了。

我用的是centos7提示:line 22: syntax error near unexpected token `fi'
并且我打印echo $current_record打印不出值,有没联系方式教我一下我的q3006139

路由器运行sh
错误提示
[Router /home/id]# ./godaddy_ddns.sh
New public IP is 100.11.xx.xx
curl: (51) Cert verify failed: BADCERT_NOT_TRUSTED
如果我使用跳过
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
则提示

syntax error: unexpected word (expecting ")")

头疼,暂时还没看到godaddy更新ip.
