自动修改主机名称并加入hosts文件-脚本

这里只写了两个案例。我这里是8网段如果地址不一样修改就好了，需要几个添几个。

根据不同的地址修改主机名，也可以修改${name}，注释掉第七行在将第八行的${name}修改成确定的主机名。 之后执行就好。

#!/bin/bash
#change host name scipts
ip=192.168.8.
ifconfig ens33|grep inet|awk '{print $2}'|grep ${ip}5
if test $? -eq 0
then
	read -p "Please enter the name that needs to be modified:" name
	hostnamectl set-hostname ${name}
#	sed -i 'a${ip}.5  ${name}' /etc/hosts
	echo "${ip}5 ${name}" >> /etc/hosts
	bash
fi
ifconfig ens33|grep inet|awk '{print $2}'|grep ${ip}6
if test $? -eq 0
then
        read -p "Please enter the name that needs to be modified:" name
        hostnamectl set-hostname ${name}
#       sed -i 'a${ip}6  ${name}' /etc/hosts
        echo "${ip}6 ${name}" >> /etc/hosts
		bash
fi
