如何解决复制文件夹结构但根据子目录中的文件夹名称通过两个不同的字符串匹配子文件夹？
如何复制整个文件夹结构，但仅根据文件夹名称通过两个不同的字符串（'Touch' 或 'mpr'）选择一些文件夹向下几个子目录？
我需要的文件在例如：
"C:\Users\Desktop\shizzle\mro\pre\subject_01\Touch"
但是有两个时间点文件夹（前和后）和几个主题，因此我尝试了更高的目录：
$includes = 'Touch|mpr'
Get-ChildItem "C:\Users\Desktop\shizzle\mro" -Directory |
Where-Object{$_.Name -match $includes} |
copy-Item -Destination "C:\Users\shizzle\Desktop\shi_data6" -Recurse -Force
这可以完美运行，但前提是搜索到的文件夹位于指定目录中，而不是多个子目录下（因此它只能在 C:\Users\Desktop\shizzle\mro\pre\subject_01 中运行）。
Get-ChildItem "C:\Users\shizzle\Downloads\copy_test\copy_test\mro" -Recurse | Where-Object{$_.Name -match $includes} | copy-Item -Destination "C:\Users\shizzle\Downloads\test_shi10" -Recurse -Force
跟不上文件夹结构。
文件夹结构如下：
C:\Users\Desktop\shizzle\mro\

解决方法
你可以试试这个：
$sourcePath = 'D:\Test' # 'C:\Users\Desktop\shizzle\mro'
$Destination = 'D:\Data' # 'C:\Users\shizzle\Desktop\shi_data6'
$includes = 'Touch|mpr'
Get-ChildItem -Path $sourcePath -Recurse -Directory |
Where-Object{$_.Name -match $includes} |
ForEach-Object {
$targetPath = Join-Path -Path $Destination -ChildPath $_.Parent.FullName.Substring($sourcePath.Length)
$null = New-Item -Path $targetPath -ItemType Directory -Force
$_ | Copy-Item -Destination $targetPath -Recurse -Force
}
除了使用上面的 Substring() 方法，您还可以使用正则表达式 -replace 来构造目标路径。
但是，请记住，路径包含对正则表达式具有特殊含义的字符，因此您应该使用源路径的 [regex]::Escape() 版本，并使用 {{1} 将其锚定到字符串的开头}：
^低于我的测试结果（当然使用不同的路径..）

$sourcePath = 'D:\Test' # 'C:\Users\Desktop\shizzle\mro'
$Destination = 'D:\Data' # 'C:\Users\shizzle\Desktop\shi_data6'
$includes = 'Touch|mpr'
# if you want to use regex `-replace` instead,use this:
$escapedSource = '^{0}' -f [regex]::Escape($sourcePath)
Get-ChildItem -Path $sourcePath -Recurse -Directory |
Where-Object{$_.Name -match $includes} |
ForEach-Object {
$targetPath = Join-Path -Path $Destination -ChildPath ($_.FullName -replace $escapedSource)
$null = New-Item -Path $targetPath -ItemType Directory -Force
$_ | Copy-Item -Destination $targetPath -Recurse -Force
}

这就是我所说的字符串操作的意思，试试这个，看看它是否有效：
$basePath="C:\Users\shizzle\Downloads\copy_test\copy_test\mro\"
$includes = 'Touch|mpr'
$destinationPath="C:\Users\shizzle\Downloads\test_shi10"
Get-ChildItem $basePath -Recurse -Directory |
Where-Object{$_.Name -match $includes} | %{
$manipulatedPath=Join-Path $destinationPath -ChildPath ($_.FullName -replace $basePath)
Copy-Item -Path $_.FullName -Destination $manipulatedPath -Recurse -Force
}
编辑：
为了测试，我在一个测试文件夹中有很多文件夹（忽略它们的名字），我会尝试这个副本而不实际复制文件夹，而是查看它们的“目标路径”是什么。代码如下：
$basePath='/home/zen/Documents/test'
$destinationPath="/home/zen/Desktop/copied_folders"
$i='#'*30
"
$i
My Test Folders:
"
(Get-ChildItem $basePath -Recurse -Directory).FullName
"
$i
My Destination Folders:
"
Get-ChildItem $basePath -Recurse -Directory | %{
$manipulatedPath=Join-Path $destinationPath -ChildPath ($_.FullName -replace $basePath)
$manipulatedPath
}
这是我的 PS 主机向我显示的假定目标路径：
