Linux系统操作网卡的指令：
service network start：启动网卡
service network restart：重启网卡
service network stop：关闭网卡
service network status：查看网卡的状态
Linux系统当中针对防火墙的操作：
service iptables start：启动防火墙
service iptables restart：重启防火墙
service iptables stop：关闭防火墙
service iptables status：查看防火墙的状态
Linux当中查看文件大小的指令
du -sh：查看当前文件的大小-->不要在根目录使用
[root@localhost /]# cd wuhan
[root@localhost wuhan]# du -sh
12K        .
[root@localhost wuhan]# cd /
[root@localhost /]# du -sh wuhan
12K        wuhan
[root@localhost /]#
Linux系统当中查看系统的操作位数？
getconf LONG_BIT:查看系统的操作位数
Linux系统当中软链接以及硬链接
硬链接：备份   ln -n 进行备份
ln -n 原文件 备份文件名：[root@localhost /]# ln -n shanghai.txt sh.txt
软链接：快捷方式  ln -s  创建快捷方式
在系统当中，他可能有的文件很常用，但是目录层级很深，这个时候可以在根目录创建一个快捷方式
ln -s 文件/目录的绝对路径 回车：[root@localhost /]# ln -s /wuhan/wuhan1/wuhan2
注意：你在哪个路径下面创建软链接，那么这个软链接就显示在你当前的路径位置
l 开头 文件/目录 代表软件来的标识（链接文档）
-文件
     d目录
