adb shell %DIR%

`adb shell %DIR%` 这条命令是一个用于在 Android Debug Bridge (ADB) 环境下执行的命令行指令。

ADB 是一个用于连接、控制和管理安卓设备的工具集，它提供了一系列命令来帮助开发者调试和测试他们的应用。当你在计算机上运行 `adb shell` 命令并接收到提示符时，你可以执行一系列 shell 命令来查看和操作你的设备。

`%DIR%` 是一个环境变量，在 Windows 中表示当前目录的路径。因此，当您在 ADB shell 下输入 `adb shell %DIR%` 时，实际上是在请求显示当前设备的工作目录或文件夹路径。

这条命令通常用于检查设备上的工作目录，例如在推送文件或下载文件到设备之前。这有助于确保文件被正确地放置在了预期的位置。

adb shell mount -t 这条命令的作用什么？-t代表什么意思？

`adb shell mount -t` 是一个用于在Android设备的shell下挂载文件系统的命令。

`-t` 是`mount`命令的一个选项，用于指定要挂载的文件系统的类型。在这个例子中，`-t debugfs` 指定要挂载的文件系统类型为debugfs，即调试文件系统。

通常情况下，mount命令的语法为：

mount [-o options] [-t type] device dir

其中，`-o`用于指定挂载选项，`-t`用于指定文件系统类型，`device`指定要挂载的设备或文件，`dir`指定挂载目录。所以，`adb shell mount -t debugfs none /sys/kernel/debug`这条命令的作用是将debugfs文件系统挂载到/sys/kernel/debug目录下，没有指定具体的设备，而是使用了none占位符作为设备参数。这样就可以在/sys/kernel/debug目录下访问和修改调试信息。
