powershell - Remove-Item提示确认时如何自动选择 "No"？

Question

使用 PowerShell 时 Remove-Item删除一个非空的目录，它会提示确认:

PS C:\Users\<redacted>\Desktop\Temp> Remove-Item .\Test

Confirm
The item at C:\Users\<redacted>\Desktop\Temp\Test has children and the Recurse parameter was not specified. If you
continue, all children will be removed with the item. Are you sure you want to continue?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"):

如果我在非交互模式下运行 powershell，则会出现错误:

Remove-Item : Windows PowerShell is in NonInteractive mode. Read and Prompt functionality is not available.
At line:1 char:1
+ Remove-Item .\Test
+ ~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Remove-Item], PSInvalidOperationException
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RemoveItemCommand

我知道我可以使用 -Recurse有 Remove-Item就像我选择了"is"选项一样继续。我可以以某种方式继续，就好像我选择了“否”选项一样？

(只是为了清楚起见: -Force 和 -Confirm:$false 不是我想要的。)

Answer 1

在尝试删除目录之前，您可以使用 test-path 来确定目录是否为空:

if (-not (Test-Path .\Test\*.*))
  { Try 
     { Remove-Item .\Test -ErrorAction Stop }
    Catch { Continue }
  }

Try Catch 将处理任何错误
