十. 命令学习方法说明
此处以 ls 命令为例
ls : 展示当前路径下有哪些文件
ls -a : 显示当前路径下的所有文件(包含隐藏文件(文件名以.开头的))
ls -l : 显示当前路径下文件的详细信息
ls -al : 显示当前路径下文件的详细信息(包含隐藏文件)
注意:
1. 命令选项连用形式为: 命令主体 -选项1选项2
2. 命令主体和选项之间必须包含一个空格
3. 命令选项的作用一般是用来扩展命令主体功能的
学习方法:
1. 优先搞清楚命令主体的含义
2. 根据实际需求结合帮助命令查找命令选项
3. 没用过的选项, 尝试自己搭建场景, 试验后看效果
4. 孰能生巧, 相较于死记命令, 勤加练习更合理一些!

虚拟机常规操作:显示隐藏文件
如图开启选项即可
