用到的工具为tree，是一个命令行工具。
首先在Linux下试试，在我的树莓派上如下：
[root@raspberrypi31 ~]# apt install tree

[root@raspberrypi31 tmp]#效果还行，可以用流直接生成到文件中：
[root@raspberrypi31 tmp]# tree bilibili/ > arch.txt看起来Linux上是没问题的，那Windows呢？找了下，发现Windows自带这个工具！！？直接tree搞起来。
D:\gitRepo\bilibili>tree /?
以图形显示驱动器或路径的文件夹结构。
TREE [drive:][path] [/F] [/A]
/F 显示每个文件夹中文件的名称。
/A 使用 ASCII 字符，而不使用扩展字符。
D:\gitRepo\bilibili>tree /a /f > output.txt
D:\gitRepo\bilibili>可以看到Windows下选项很少，只有2个，如果要玩骚操作还是上Linux吧，但正常使用Windows的应该够了。
