Recursively copy a set of files from one directory to another in PowerShell
提问by Mike Christensen
I'm trying to copy all *.csproj.userfiles recursively from C:\Code\Trunkto C:\Code\F2.
我正在尝试将所有*.csproj.user文件递归复制C:\Code\Trunk到C:\Code\F2.
For example:
例如：
C:\Code\Trunk\SomeProject\Blah\Blah.csproj.user
C:\Code\Trunk\SomeProject\Blah\Blah.csproj.user
Would get copied to:
将被复制到：
C:\Code\F2\SomeProject\Blah\Blah.csproj.user
C:\Code\F2\SomeProject\Blah\Blah.csproj.user
My current attempt is:
我目前的尝试是：
Copy-Item C:\Code\Trunk -Filter *.csproj.user -Destination C:\Code\F2 -Recurse -WhatIf
复制项目 C:\Code\Trunk -Filter *.csproj.user -Destination C:\Code\F2 -Recurse -WhatIf
However I get:
但是我得到：
What if: Performing operation "Copy Directory" on Target "Item: C:\Code\Trunk Destination: C:\Code\F2\Trunk".
如果：在目标“项目：C:\Code\Trunk 目的地：C:\Code\F2\Trunk”上执行“复制目录”操作。
First, it wants to put them all in a new folder called F2\Trunkwhich is wrong. Second, it doesn't list any of the files. There should be about 10 files to be copied over.
首先，它想将它们全部放在一个名为F2\Trunkwhich 错误的新文件夹中。其次，它没有列出任何文件。应该有大约 10 个文件要复制。
What's the correct syntax for the command? Thanks!
命令的正确语法是什么？谢谢！
Update:
更新：
Okay, it seems to have something to do with the fact that C:\Code\F2already exists. If I try copying the files over to a destination that does notexist, it works.
好吧，这似乎与C:\Code\F2已经存在的事实有关。如果我尝试将文件复制到不存在的目的地，它会起作用。
I want to overwriteany existing .csproj.userfiles in the destination.
我想覆盖.csproj.user目标中的任何现有文件。

Seen this before, and I don't know why PowerShell can't seem to get it right (IMHO). What I would do is more cumbersome but it works.
以前见过这个，我不知道为什么 PowerShell 似乎无法正确处理（恕我直言）。我会做的更麻烦，但它有效。
$Source = 'C:\Code\Trunk'
$Files = '*.csproj.user'
$Dest = 'C:\Code\F2'
Get-ChildItem $Source -Filter $Files -Recurse | ForEach{
$Path = ($_.DirectoryName + "\") -Replace [Regex]::Escape($Source), $Dest
If(!(Test-Path $Path)){New-Item -ItemType Directory -Path $Path -Force | Out-Null
Copy-Item $_.FullName -Destination $Path -Force
}

You guys are making this hideously complicated, when it's really simple:
你们把这搞得异常复杂，其实很简单：
Copy-Item C:\Code\Trunk -Filter *.csproj.user -Destination C:\Code\F2 -Recurse
Will copy the Directory, creating a "Trunk" directory in F2. If you want to avoid creating the top-level Trunk folder, you have to stop telling PowerShell to copy it:
将复制Directory，在 F2 中创建一个“Trunk”目录。如果你想避免创建顶级 Trunk 文件夹，你必须停止告诉 PowerShell 复制它：
Get-ChildItem C:\Code\Trunk | Copy-Item -Destination C:\Code\F2 -Recurse -filter *.csproj.user

While the most voted answer is perfectly valid for single file types, if you need to copy multiple file types there is a more useful functionality called robocopy exactly for this purpose with simpler usage
虽然投票最多的答案对单一文件类型完全有效，但如果您需要复制多种文件类型，则有一个更有用的功能，称为 robocopy 正是为此目的，使用更简单
robocopy C:\Code\Trunk C:\Code\F2 *.cs *.xaml *.csproj *.appxmanifest /s

I tried Jaykul answer and it did not work for me. I had to change it as below to get it to work. I also created the C:\Code\F2 folder before it worked.
我尝试了 Jaykul 的回答，但对我不起作用。我必须按如下方式更改它才能使其正常工作。在它工作之前，我还创建了 C:\Code\F2 文件夹。
Get-ChildItem C:\Code\Trunk Recurse -filter *.csproj.user | Copy -Destination C:\Code\F2

Recently I had to replace a file present in several sub folders, I did it as below.
最近我不得不替换存在于几个子文件夹中的一个文件，我做了如下。
foreach($file in (Get-ChildItem File_you_want_to_be_copied.txt -Recurse)) {$target=$file.directoryname; Copy-Item -path C:\Source_Path\File_you_want_to_be_copied.txt -Destination $target}

Answer 1 looked good, and I changed to Move-Itemfor my purposes. However I found that in each folder it recursively went through, it only moved the first file. Below is my complete script which also includes some conversion of doc files to pdf's:
答案 1 看起来不错，Move-Item为了我的目的，我改为。但是我发现在它递归遍历的每个文件夹中，它只移动了第一个文件。下面是我的完整脚本，其中还包括一些 doc 文件到 pdf 的转换：
$Source = 'C:\Users\sgrody\Desktop\NSPM-Vol1'
$MoveFiles = '*.PDF'
$Dest = 'C:\Users\sgrody\Desktop\MedPassPDF'
$Folders = Get-ChildItem $Source -Directory -Recurse
ForEach ($Folder in $Folders)
{
$wdFormatPDF = 17
$word = New-Object -ComObject word.application
$word.visible = $false
$folderpath = "$($Folder.FullName)\*"
$fileTypes = "*.docx","*doc"
Get-ChildItem -path $folderpath -include $fileTypes |
foreach-object
{
$path = ($_.fullname).substring(0,($_.FullName).lastindexOf("."))
"Converting $path to pdf ..."
$doc = $word.documents.open($_.fullname)
$doc.saveas([ref] $path, [ref]$wdFormatPDF)
$doc.close()
}
$word.Quit()
}
Get-ChildItem $Source -Filter $MoveFiles -Recurse | ForEach{
$Path = ($_.DirectoryName + "\") -Replace [Regex]::Escape($Source), $Dest
If(!(Test-Path $Path)){New-Item -ItemType Directory -Path $Path -Force | Out-Null
Move-Item $_.FullName -Destination $Path -Force
}
}
