问题描述
如何复制整个文件夹结构，但只能通过两个不同的字符串("Touch"或"mpr")根据文件夹名称向下选择几个子目录中的某些文件夹?
How can one copy an entire folder structure but only select some folders several subdirectories down based on the folder name by two different strings ('Touch' or 'mpr') ?
我需要的文件位于例如:
the files I need are in e.g.:
"C:\Users\Desktop\shizzle\mro\pre\subject_01\Touch"
但是有两个时间点文件夹(Pre和Post)和几个主题，因此我尝试了更高的目录:
but there are two Timepoint-folders (Pre and Post) and several subjects, hence I have tried a higher directory:
$includes = 'Touch|mpr'
Get-ChildItem "C:\Users\Desktop\shizzle\mro" -Directory |
Where-Object{$_.Name -match $includes} |
Copy-Item -Destination "C:\Users\shizzle\Desktop\shi_data6" -Recurse -Force
效果很好，但仅当搜索到的文件夹位于指定目录中且没有多个子目录时(因此，它只能在 C:\ Users \ Desktop \ shizzle \ mro \ pre \ subject_01 ).
which works perfectly, but only if the searched folders are in the specified directory and not several subdirectories down (so it would only work in C:\Users\Desktop\shizzle\mro\pre\subject_01).
Get-ChildItem "C:\Users\shizzle\Downloads\copy_test\copy_test\mro" -Recurse | Where-Object{$_.Name -match $includes} | Copy-Item -Destination "C:\Users\shizzle\Downloads\test_shi10" -Recurse -Force
没有保持文件夹结构.
文件夹结构如下:
C:\Users\Desktop\shizzle\mro\

推荐答案
您可以尝试以下操作:
$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 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，因此您应该使用源代码的 [regex] :: Escape()版本，并将其锚定到字符串以 ^ 开头:
Instead of using the Substring() method above, you can also use regex -replace to construct the target path.
However, keep in mind that a path contains characters that have special meaning for regex, so you should then use the [regex]::Escape()'d version of the source path, and anchor it to the beginning of the string with ^:
$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
}
下面是我的测试结果(当然使用不同的路径.)
