curl命令查看请求响应时间

对于一些禁止ping 的网址可以使用curl进行测试

curl -o /dev/null -s -w %{http_code}---%{content_type}---%{time_namelookup}---%{time_namelookup}---%{time_connect}---%{time_starttransfer}---%{time_total}---%{speed_download}"\n" "http://www.baidu.com/"

-o /dev/null：把curl 返回的html、js 写到垃圾回收站[ /dev/null] -s：去掉所有状态 -w：按照后面的格式写出rt

%Q

用于替代双引号的字符串. 当你需要在字符串里放入很多引号时候, 可以直接用下面方法而不需要在引号前逐个添加反斜杠 (\")

>> %Q(Joe said: "Frank said: "#{what_frank_said}"")
=> "Joe said: "Frank said: "Hello!"""
(...)也可用其他非数字字母的符号或成对的符号代替, 诸如[...], !...!, +...+,{...}, <...>等.

以下写法全部与上面等效:
