原文:NETCore执行Shell修改Centos系统IP信息
shell代码
首先通过find命令找到/etc/sysconfig/network-scripts/目录下的ifcfg-en*的文件，然后通过sort排序，将第一个文件作为要修改的文件。
type参数表示设置的是静态IP还是动态IP
代码如下
#!/bin/bash
ip=$1
gateway=$2
netmask=$3
dns1=$4
dns2=$5
type=$6
echo "###ip:" $ip "###"
echo "###gateway:" $gateway "###"
echo "###subnetmask:" $netmask "###"
echo "###dns1:" $dns1 "###"
echo "###dns2:" $dns2 "###"
echo "###type:" $type "###"
eth=`find /etc/sysconfig/network-scripts/ -name "ifcfg-e*" |sort |head -1 |awk -F/ '{print $5}'`
ethfile="/etc/sysconfig/network-scripts/$eth"
echo "${ethfile}"
sed 's/^ONBOOT=no/ONBOOT=yes/g' "${ethfile}"
if [ $6 == "1" ]
then
echo "###dhcp###"
sed -i 's/BOOTPROTO=static/BOOTPROTO=dhcp/g' "${ethfile}"
sed -i '/IPADDR=/d' "${ethfile}"
sed -i '/GATEWAY=/d' "${ethfile}"
sed -i '/NETMASK=/d' "${ethfile}"
sed -i '/DNS1=/d' "${ethfile}"
sed -i '/DNS2=/d' "${ethfile}"
else
echo "###static###"
sed -i 's/BOOTPROTO=dhcp/BOOTPROTO=static/g' "${ethfile}"
sed -i '/IPADDR=/d' "${ethfile}"
sed -i '/GATEWAY=/d' "${ethfile}"
sed -i '/NETMASK=/d' "${ethfile}"
sed -i '/DNS1=/d' "${ethfile}"
sed -i '/DNS2=/d' "${ethfile}"
echo "IPADDR=${ip}" >>${ethfile}
echo "GATEWAY=${gateway}" >>${ethfile}
echo "NETMASK=${netmask}" >>${ethfile}
echo "DNS1=${dns1}" >>${ethfile}
echo "DNS2=${dns2}" >>${ethfile}

Console.WriteLine("your arguments is:" + arguments);

注意事项
1.在shell脚本的开头往往有一句话来定义使用哪种sh解释器来解释脚本，本例中使用#!/bin/bash
2.注意shell脚本的文件编码，如果编码不是Linux能识别的，C#执行Linux脚本出错，出现No Such file or directory异常。所以建议在Linux下用touch指令创建shell文件，vi编辑文件。
3.shell修改IP信息设置后的配置文件如下。这是Centos7的IP配置，一定是正确的，如果设置完后网络异常首先考虑网关子网掩码是不是设置错了。
