终端下显示网速的SHELL脚本

<div >除了视频, 终端下的生活已经很完美和效率了 
( framebuffer: 喂, 我可以让你在字符界面看电影的... ) 
 
 
我几乎用不到X, 而且X20的配置, 开X有点虚... 
 
 
more /proc/cpuifon ; free ; df ; top 
可以看一些系统的状况, 比如CPU信息, 内存, 硬盘, 进程... 
但是dorainm一直没有找到一款能即时显示网速的 
比如 eth0上传 xx KB/S 
虽然 /sbin/ifconfig 可以查看网络状态 
 
 
毛主席告诉我们, 自动动手, 丰衣足食 
因为 /sbin/ifconfig 里面有条信息, 
告诉我们当前某个连接的总数据量 total bytes 
 
 
如果我们每1秒钟去获取这个total bytes 
然后把两次结果相减, 不就可以获得 xx B/S的网络速度了吗?? 
 
 
当然, 这个数字也会一时无法直观表示, 
比如当这数字大于 1024时候, 就转化为 KB/S 的单位 
如果数字大于 1024*1024, 就转化为 MB/S 
... ... 
这样子结果就比较直观了 
 
 
okay, let's go 
rate程序写了有一年了吧, google了好多拼凑出来的 
代码很难阅读, 本来想什么时候优化一下, 发布出来 
但是一直没有做, 今天决定还是拿出来让需要的群众来使用吧

这样测试似乎不是很准确的，而且使用ifconfig已经很明显了。
