-O：使用URL中默认的文件名保存文件到本地

指令：curl
在linux中curl是一个利用URL规则在命令行下工作的文件传输工具，可以说是一款很强大的http命令行工具。它支持文件的上传和下载，是综合传输工具，但按传统，习惯称url为下载工具。
语法：# curl [option] [url]
常见参数：
-A/--user-agent <string> 设置用户代理发送给服务器
-b/--cookie <name=string/file> cookie字符串或文件读取位置
-c/--cookie-jar <file> 操作结束后把cookie写入到这个文件中
-C/--continue-at <offset> 断点续转
-D/--dump-header <file> 把header信息写入到该文件中
-e/--referer 来源网址
-f/--fail 连接失败时不显示http错误
-o/--output 把输出写到该文件中
-O/--remote-name 把输出写到该文件中，保留远程文件的文件名
-r/--range <range> 检索来自HTTP/1.1或FTP服务器字节范围
-s/--silent 静音模式。不输出任何东西
-T/--upload-file <file> 上传文件
-u/--user <user[:password]> 设置服务器的用户和密码
-w/--write-out [format] 什么输出完成后
-x/--proxy <host[:port]> 在给定的端口上使用HTTP代理
-#/--progress-bar 用进度条显示当前的传送状态
用curl的内置option就好，存下http的结果，用这个option: -o
curl -o page.html http://www.yahoo.com
大写的O，这么用：这样，就可以按照服务器上的文件名，自动存在本地了
curl -O http://cgi2.tky.3web.ne.jp/~zzh/screen1.JPG
访问不到？肯定是你的proxy没有设定了。
使用curl的时候，用这个option可以指定http访问所使用的proxy服务器及其端口： -x
curl -x 123.45.67.89:1080 -o page.html http://www.yahoo.com
