cme.sh網絡流量監控使用
[root@china213 ~]# cd /bin
[root@china213 bin]# ./cme.sh

disk 39

nic 19855 33 0

CPU剩余率，磁盤剩余率，內存剩余率，以及網卡接收的bps,pps和dps（丟包）
把下面內容用vi命令寫入到cme.sh中[root@china213 bin]# vi cme.sh，同時用[root@china213 bin]# chmod +x cme.sh增加可執行權限
注意：shell文件開頭必須以#!/bin/sh開始，在window中保存成cme.sh上傳的時候會執行不了，可能是文件頭的問題。
==============================不要把這行分各符放到cme.sh文件中=========================================
