终端下显示网速的SHELL脚本

时间：2007-06-16 来源：dorainm

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

运行

$ rate --help
usage : /home/dorainm/bin/rate [DEV_NAME] [ TIMES | -t ]

  DEV_NAME the name of the network device, default: eth0
  TIMES    the times of counts, default: 1
  -t       counting until break
$

比如查看 lo 1次( 1秒钟 ) 的网络速度

$ rate lo

下面看持续观看 eth0 的网络速度
