| 实验前： a、先创建root账户 rt b、测试下网络，方便后续安装所需的工具包 c、查看ip（留个疑问，这里的IP 是172.28.137.241/20与宿主机10.255.50.5有什么关系？） d、安装所需的工具：net-tools linux@peggy0223:/$ su root Password: root@peggy0223:/# apt install net-tools Reading package lists...

| 现在开始实验内容：（p405，文件、目录操作命令）内容会尽量丰富点，大家按书本的实验内容做即可。 |
| 复习常用的命令：pwd、cd、mkdir、cat、cp、rm、mv、chown、chmod、echo、more、less、tar、man、find、compress、uncompress、gzip、gunzip、alias 实验内容：一、目录切换pwd、cd'~'、'-'、'.'、'/'、'../..'等的意义，如图，请自行理解二、echo、cat、more、less、cp、rm、mv结合对文本\文件的操作使用三、mkdir、chown、chmod 四、tar、alias、gzip、gunzip compress、uncompress在unbutu中可用gzip替代， root@peggy0223:/home/linux# apt install bzip2 五、man、find、alias find的命令略。以上命令熟悉后，建议结合课本自学find的命令的使用。 |
