Ubuntu device IP continuous ping check script

---

foreword

Since the work project needs to check whether more than 30 devices are running normally and whether the delay is large, the operating environment is the Ubuntu system, so a script is written to provide a quick check;

---

The script content is as follows:

#!/bin/bash
##ping IP BY-Holden
echo -e "\033[43;30m =====>             连接检查               <===== \033[0m"
ip=64
while [ $ip != "96" ]; do
ping 10.151.23.$ip -c 2 | grep -q "time=0." && echo -e "\033[32m 10.151.23.$ip OK\033[0m" || echo -e "\033[31m 10.151.23.$ip 不通或延时很高\033[0m"
ip=`expr "$ip" "+" "1"`
done
