Powershell 5将项目目录复制到目录错误

Question

我是 Powershell 新手，正在根据 this documentation 测试 Copy-Item 的功能。我正在尝试将文件和文件夹从子文件夹复制到它的包含文件夹中，但它不起作用。我需要使用什么命令？

这是我的示例文件结构

C:\
    Example
    |
    |__Top
        |
        |__Middle
            |
            |__Bottom

我尝试将所有文​​件和子文件夹从 Middle 复制到 Top 使用

Copy-Item "C:\Example\Top\Middle" -Destination "C:\Example\Top" -Recurse

但收到此错误

Copy-Item : An item with the specified name C:\Example\Top\Middle already exists.

Answer 1

您试图将子文件夹复制到其父文件夹。要复制“中间”文件夹的内容，您需要使用以下命令：

Copy-Item "C:\Example\Top\Middle\*" -Destination "C:\Example\Top" -Recurse

Answer 2

我相信这将完成您正在寻找的最简单的示例。它需要根据您的情况进行调整。

-需要应用强制来覆盖。

$source = "C:\Example\Top\Middle\*"

$destination = "C:\Example\Top\"

Copy-Item -Path $source -Destination $destination -Include *.*
