偶尔在网站上发现了cur命令

1.其中的一个方法是

#curl --head http://www.xunlei.com
HTTP/1.1 200 OK
Server: nginx/0.6.31
Date: Thu, 21 May 2009 01:49:30 GMT
Content-Type: text/html
Transfer-Encoding: chunked
Connection: keep-alive
Expires: Thu, 21 May 2009 01:50:30 GMT
Cache-Control: max-age=60

可以看到迅雷使用的是nginx版本号是0.6.31

$ curl --head http://www.google.com
HTTP/1.1 200 OK
Cache-Control: private, max-age=0
Date: Thu, 21 May 2009 01:51:10 GMT
Expires: -1

$curl --head http://www.qq.com

具体的使用方法是curl --help

man curl
