写了有一段时间了，批处理模块就不展示了，
主要是思路，同时把ip配置文件和修改ip脚本传到目标机器上；
目标机器根据配置文件修改ip
修改ip脚本如下
#!/bin/bash
file_name=test.txt
oldip=`cat $file_name|grep -iA3 eth0 | grep address | grep -oP '([0-9]{1,3}\.){3}[0-9]{1,3}'`
oldmask=`cat $file_name|grep -iA3 eth0 | grep netmask | grep -oP '([0-9]{1,3}\.){3}[0-9]{1,3}'`
oldgate=`cat $file_name|grep -iA3 eth0 | grep gateway | grep -oP '([0-9]{1,3}\.){3}[0-9]{1,3}'`
##############################

newmask='255.255.255.0'
newgate='10.44.133.1'
echo '旧的ip:'
echo $oldip
echo $oldmask
echo $oldgate
echo '----------------------'
echo '新的ip'
newip=`cat ipconf.txt | grep $oldip | awk '{print $1}'`
echo $newip
echo $newmask
echo $newgate
sed -i 's/'$oldip'/'$newip'/' $file_name
sed -i 's/'$oldmask'/'$newmask'/' $file_name
sed -i 's/'$oldgate'/'$newgate'/' $file_name
