写了个bash脚本查看系统运行概况

系统debian6 x86_64

因为要几十个小时运行个占用大量资源易死锁的东西，开了一堆监控看
所以想集中到一个窗口，造了个轮子

#!/bin/bash
for((i=1;i<=999999999;i++))
do
ins=$(cat /proc/net/dev | sed -n '4,4p' | sed 's/eth0://g' | awk '{print $1}')
outs=$(cat /proc/net/dev | sed -n '4,4p' | sed 's/eth0://g' | awk '{print $9}')
sleep 1s
ine=$(cat /proc/net/dev | sed -n '4,4p' | sed 's/eth0://g' | awk '{print $1}')
oute=$(cat /proc/net/dev | sed -n '4,4p' | sed 's/eth0://g' | awk '{print $9}')
in=$[($ine-$ins)/1024]
out=$[($oute-$outs)/1024]
echo "in-out-k:" $in $out " conn:" $(netstat -an | wc -l) " inode:" $(df -i | grep sdb | awk '{print $3}') " bi-bo:"$(vmstat | sed -n '3,3p' | awk '{print " " $9 " " $10}') " load:" $(uptime | sed 's/,//g' | awk '{print $8" on "$1}')
done

in-out-k 以k为单位显示当前进出流量
conn 就是netstat -an的数量，我需要看的是上下的巨大差异
inode sdb盘的文本使用情况
bi-bo sdb盘的bi bo其它盘基本没啥读写
load 当前负载
on 当前时间

第一次写bash 基本上是边查边写效果还不错啊

输出是这样子的：
