如何使用grep查询出不包含某匹配模式的文件

配置ip
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:50:2E:7D:F3:45
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.0.8
USERCTL=no
PEERDNS=yes
GATEWAY=192.168.0.1
IPV6INIT=no

DNS
vi /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

添加用户
useradd testuser
passwd testuser

防火墙
vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

service iptables stop
service iptables start

ssh
vi /etc/ssh/sshd_config
/etc/rc.d/init.d/sshd start stop restart
service sshd start stop restart

重启网络服务的命令是
service network restart
或者/etc/init.d/network restart
