Shell script to check if the Linux host is up or not

In this script we are checkiing if the host is responsive and alive or not. Also it will send mail.

I am going to pass a parameter for host which needs to be check.

vi host_alive.sh

#!/bin/bash

host_check=$1

count=$( ping -c 1 $host_check | grep icmp* | wc -l )

if [ $count -eq 0 ]

then

echo "Host is not Alive! Please check.." |mailx -s "Critical: $host_check is not responsive"

else

echo "Yes! Host is Alive!"

Usage:

./host_alive.sh funebs122.lab
