Powershell-列出所有文件夹、子文件夹和每个包含的文件（递归），但采用格式化方式（树状视图）

我在powershell上使用以下命令创建特定目录中所有文件和子文件夹的列表：

get-childitem -path c:\users\username\desktop\test -recurse | select name

因此，假设我的桌面上有一个名为“test”的文件夹，在这个文件夹中，我有三个文件和一个子文件夹，它本身包含更多的文件和子文件夹等等，我会得到如下输出：

subfolder 1 of "test"
file 1 in "test"
file 2 in "test"
file 3 in "test"
subfolder a of "subfolder 1"
file 1 in subfolder 1
file 2 in subfolder 1
file 3 in subfolder 1
file 1 in subfolder a
file 2 in subfolder a
file 3 in subfolder a

这很好，但我想得到另一种输出，如下所示：

+  c:\users\username\desktop\test
|  -  file 1 in "test"
|  -  file 2 in "test"
|  -  file 3 in "test"
|--+  subfolder 1 of "test"
|  |  -  file 1 in subfolder 1
|  |  -  file 2 in subfolder 1
|  |  -  file 3 in subfolder 1
|  |--+  subfolder a of "subfolder 1"
|  |  |  -  file 1 in subfolder a
|  |  |  -  file 2 in subfolder a
|  |  |  -  file 3 in subfolder a
|--+  subfolder 2 of "test"
|  |  -
|  |  .
|  .  .
.  .
.

有没有可能（如果有，怎么做？）得到这样的输出？ 我知道当时有一个名为“tree”的dos命令，但由于其局限性，它无法在powershell中处理get childitem的输出。powershell中是否有某种等效命令，或者我可以使用get childitem命令及其开关/additions/

对不起，我的英语不好。 还有：对不起，我对powershell完全是个初学者

感谢您的帮助。

您习惯于从cmd中获取的旧“树”是system32文件夹中的应用程序，而不是一些硬编码的cmd功能

因此，您仍然可以像往常一样从powershell运行它

e、 g

Robocopy和其他一些著名的应用程序也以同样的方式工作

外部程序中的错误可以在$LastExitCode而不是通常的$Error中捕获。这些代码的含义将因程序而异。

您可以从Powershell调用任何cmd/DOS可执行文件。只要你做得好。在consolehost（powershell.exe/pwsh.exe）中，它实际上与使用cmd.exe相同，但在ISE中有所不同。不能在ISE中使用交互式命令。您可以使用该命令，但必须传递它所需的所有信息

在PowerShell控制台主机（PowerShell.exe/pwsh.exe）中，只需键入

$PSVersionTable
