After reading some questions from the Internet, I wrote a simple script, which is not strictly enough. For example, I can only modify the e'h0 and cannot modify eth1, you can also add it to the script by yourself. This small shell only provides some help. I am also a beginner in shell. Please give me more instructions.

Change the ip address, IP_MODI = ××××, and mask MASK_MODI = ××××.

#! /Bin/sh
PROC =/bin/sed
FILE_PATH =/etc/sysconfig/network-scripts/ifcfg-eth0
IP_PRIMAL = 'grep-I ipaddr $ FILE_PATH | awk-F "=" '{printf $2 }''
MASK_PRIMAL = 'grep-I netmask $ FILE_PATH | awk-F "=" '{printf $2 }''
$ PROC-e "s/$ IP_PRIMAL/$ IP_MODI/g"-e "s/$ MASK_PRIMAL/$ MASK_MODI/g" $ FILE_PATH> ifcfg-eth0.bak
Cp-pf./ifcfg-eth0.bak $ FILE_PATH
# Restart network command
#/Etc/init. d/network restart>/dev/null 2> & 1
