求助，帮忙修改一个脚本，可以检查指定文件中列表IP的主机存活情况

googel了好久找到的都是 检测内网中存活主机，我需要的是从主件导入IP
下面这个脚本不错可惜就是只能指定网段来检测，能不能请高手 帮我修改下可以指定文件 来检测

#!/bin/bash
# Simple SHELL script for Linux and UNIX system monitoring with
# ping command
# code by robert
for ((a=1;a<=255;a++));do
HOSTS="192.168.132.$a"
COUNT=1
for myhost in $HOSTS
do
count=$(ping -c $COUNT $myhost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')
if [ $count -eq 0 ]; then # 100% failue
echo "$myhost is down (ping failed)"
else
echo "$myhost is up"
fi
done
done

COUNT=1
while read -r myhost
do
count=$(ping -c $COUNT $myhost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')
if [ $count -eq 0 ]; then # 100% failue
echo "$myhost is down (ping failed)"
else
