如何解决Powershell-列出所有文件夹,子文件夹和每个包含的文件递归,但以格式化的方式树视图列出
我在powershell上使用以下命令来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,并且在此文件夹中,我有三个文件和一个子文件夹,它本身还包含其他文件和子文件夹,依此类推,我确实得到了类似的输出: / p>
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,但是我想获得另一种输出,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"
| | -
| | .
| . .
. .
.
是否有可能(如果是,怎么办?)获得像这样的输出? 我知道当时有一个dos命令称为“ tree”,但由于其局限性,它无法与powershell中的get-childitem输出配合使用。 Powershell中是否存在某种等效命令,或者我可以使用get-childitem命令及其开关/添加项/ ...来做到这一点吗?
抱歉,我的英语不好。 而且:对不起,我是Powershell的初学者。
谢谢您的帮助。
解决方法
您习惯于从cmd中使用的旧“树”是system32文件夹中的应用程序,而不是某些硬编码的cmd功能。
因此您仍然可以像往常一样从powershell运行它。
例如
Tree 'C:\Foldername'
Robocopy和其他一些知名应用程序的工作方式相同。
可以在$ LastExitCode中捕获外部程序中的错误,而不是通常的$ Error。这些代码的含义将取决于程序。
,您可以从Powershell调用任何cmd / DOS可执行文件。只要您这样做正确。在consolehost(powershell.exe / pwsh.exe)中,它实际上与使用cmd.exe相同,但是在ISE中则有所不同。您不能在ISE中使用交互式命令。您可以使用该命令,但必须通过它。
在PowerShell控制台主机(powershell.exe / pwsh.exe)中,只需键入...
