Linux 下的这些小工具实在是太有用了。一个个顺手的工具，用shell脚本连接起来就是个强大的工具。

curl，居然可以模拟浏览器。

-b/–cookie   发送保存的cookie给浏览器。
-c/–cookie-jar 保存浏览器发给的cookie。

#curl -c cookie www.baidu.com
#more cookie

# Netscape HTTP Cookie File
# http://www.netscape.com/newsref/std/cookie_spec.html
# This file was generated by libcurl! Edit at your own risk.

.baidu.com      TRUE    /       FALSE   4294967295      BAIDUID C5AE008C713292B6C59FEDACE943B674:FG=1

-D/–dump-header   保存协议的头文件。
例如：
#curl -D httpheader www.baidu.com
# more httpheader

> |grep 'ul class="ul1"'
> |sed -e 's/^.*">
/t/' -e 's/
/nt/g' -e 's/<.*$//'

提交一个表单，而且这个表单是个POST请求。如果是GET，可直接加在url的后面。
eg：
在百度查询sunliguo：

curl www.baidu.com/s?wd=sunliguo
