shell-read交互配置hostname、bond、salt、ip

#!/bin/bash
#=========set hostname====================
stty erase ^H		#避免read交互是按退格键出现 ^H
read -p "Please enter hostname:" hostname
hostnamectl set-hostname $hostname

#=========config bond=====================
stty erase ^H
read -p "Please enter your IP:" ip
GW=`echo $ip |awk -F "." '{print $1"."$2"."$3"."1}'`

/usr/bin/ping -c 3 $ip > /dev/null 2>&1
if [ $? -eq 0 ];then
        echo "$ip existing"
        exit 1
else
        echo "ip ok!"
