我有一个shell脚本来更改IP地址（在CentOS上），而不是手动更改。下面是脚本：

#!/bin/bash
# changeip.sh

usage(){
    clear
    echo "Usage: $0 newip"
    echo "Example: $0 127.0.0.1"
    exit 1
}

new_ip_value=$1
local_ip_value=$(ifconfig eth0|awk '/inet addr/ {split ($2,A,":"); print A[2]}')

# call usage() function if filename not supplied
    [[ $# -eq 0 ]] && usage

echo "/etc/hosts"
echo "----------------------------------------------------------"
sed -ie 's/'$local_ip_value'/'$new_ip_value'/g' /etc/hosts
sed 's/'$local_ip_value'/'$new_ip_value'/g' /etc/hosts
echo ""
echo "/etc/sysconfig/network-scripts/ifcfg-eth0"
echo "----------------------------------------------------------"
sed -ie 's/'$local_ip_value'/'$new_ip_value'/' /etc/sysconfig/network-scripts/ifcfg-eth0
sed 's/'$local_ip_value'/'$new_ip_value'/' /etc/sysconfig/network-scripts/ifcfg-eth0
echo "The IP of $local_ip_value has successfully been changed to $new_ip_value."
service network restart

exit

字符串
我需要添加更多的参数，如：

1. BOOTPROTO
   1.启动
   1.网关
2. DNS1
   等
   有没有人能告诉我应该如何修改脚本来添加这些细节？我的ifcfg-eth0最终应该是这样的：

# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="yes"
ONBOOT=yes
TYPE="Ethernet"
IPADDR=192.168.1.2
GATEWAY=192.168.1.1
