【linux专用（包括steamdeck】修改hosts文件以解决steam无法登录，社区无法打开的问题

#!/bin/bash

#备份hosts

cp /etc/hosts /etc/hosts.bak

#删除hosts中带有steam字样的行

sed -i "/steam/d" /etc/hosts

#获取steamcommunity.com和store.steampowered.com通过谷歌dns解析到的IP

comip=`nslookup steamcommunity.com 8.8.8.8 | grep -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | grep 'Address' | grep -v '#' | sed 's/Address: //g'`

storeip=`nslookup store.steampowered.com 8.8.8.8 | grep -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | grep 'Address' | grep -v '#' | sed 's/Address: //g'`

#将解析到的IP和对应的域名写入hosts

echo $storeip store.steampowered.com >> /etc/hosts

echo $comip steamcommunity.com >> /etc/hosts
