Question

使用PowerShell的Remove-Item删除非空目录时，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，我会收到错误：

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让Remove-Item继续进行，就像我选择了“是”选项一样。我可以以某种方式继续进行，就好像我选择了“否”选项一样吗？

（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，可以使用test-path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

Answer 2

这对我有用。文件不会被删除，脚本继续。您仍然会看到有关NonInteractive模式的错误，但该命令会继续，就像No答案一样。

remove-item c:\test\test

Write-host "Files are still there, script still going"

如果您只是想要禁止该错误消息将其包装在Try \ Catch

中

Try
{
remove-item c:\test\test 
}
Catch
{

}

Write-host "Files are still there, script still going"

当Remove-Item提示确认时，如何自动选择“否”？
