linux使用curl代理和检查及代理脚本sh
curl 检测代理
curl https://byy3.com -m 10 -o out.html --socks4 91.99.99.11:1080
说明：
curl shell 抓取网页命令
-m 10 连接超时时间，最大为10秒
-o out.html 抓取网页输出到 out.html
--socks4 91.99.99.11:1080 代理协议采用 --socks4
此外，curl 7.21.7版本以上，还支持代理协议格式如下：
curl https://byy3.com -m 10 -o out.html -x socks4://91.99.99.11:1080
或
curl https://byy3.com -m 10 -o out.html --proxy socks4://91.99.99.11:1080
更多请详见米扑代理的代码示例：

下面是验证脚本代码proxy.sh添加权限chmod +x proxy.sh
