批量ping存活主机

创建一个ip.txt文件，把需要测试IP地址写入文档

创建一个ping.sh 的shell 脚本，并修改ip.txt 文件路径

#!/bin/bash
for ips in `cat /root/manager/script/ip.txt`
do
        result=`ping -w 2 -c 3 ${ips} | grep packet | awk -F" " '{print $6}'| awk -F"%" '{print $1}'| awk -F' ' '{print $1}'`
        if [ $result -eq 0 ]; then
                echo ""${ips}" is ok !"
        else
                echo ""${ips}" is not connected ....."
        fi

done

给脚本执行权限 chmod +x ping.sh

执行脚本

[root@k8s-node1 script]# ./ping.sh 
172.31.8.101 is ok !
172.31.8.192 is ok !
172.31.8.42 is ok !
172.31.8.176 is ok !
172.31.8.45 is ok !
[root@k8s-node1 script]#
