shell脚本批量ping IP

1、系统环境

系统：centos7

2、shell脚本

#!/bin/bash
#开启所有网口并配置IP地址
ifconfig eth0 192.168.2.10 up
sleep 0.001
ifconfig eth1 192.168.3.10 up
sleep 0.001
ifconfig eth4 192.168.5.10 up
sleep 2
#循环执行命令
while true
do
#查看预先加入的IP地址池，并逐个读取
ipAll=$(cat /root/ip_record.text)
for ip in $ipAll
do
echo $ip
#逐个ping读取的IP地址并输出time值
num=$(ping -c 2 $ip |grep packets |awk '{print $7}' |awk -F . '{print $1}')
time=$(ping -c 2 $ip |grep time |awk '{print $7}')
echo $time
#输出ping包时间
echo "DATE:" $(date +"%Y-%m-%d %H:%M:%S")
判断ping包是否连通，如果没有ping通则输出错误的IP地址和时间到日志文件，ping通则输出time值和OK字样
if [ $num == "errors," ];then
#echo $num fail
echo "error date:" $(date +"%Y-%m-%d %H:%M:%S")
echo "     Femrice     " >> Network$LogNameDATE.log
echo "-----------------" >> Network$LogNameDATE.log
echo "DATE:" $(date +"%Y-%m-%d %H:%M:%S") >> Network$LogNameDATE.log
echo $ip >> Network$LogNameDATE.log
else
echo $num ok
fi
done

3、输出结果
