powershell复制文件并将文件夹名附加到复制的文件

Question

我正在尝试从根文件夹下的 daily 文件夹复制文件 "abc.txt"。假设源文件夹路径和文件看起来像..

\Server01\rootdir->01-01-20->abc.txt
\Server01\rootdir->01-01-20->abc.txt
\Server01\rootdir->01-01-20->Details->abc.txt
..
..
\Server01\rootdir->10-25-20->Details->abc.txt
\Server01\rootdir->11-15-20->abc.txt
\Server01\rootdir->12-30-20->abc.txt           ---File existed in parent folder
\Server01\rootdir->12-31-20->Details->abc.txt  ---File not in parent but in child

我想将所有这些文件夹中的 abc.txt 个文件复制到一个位置。但是在复制时我需要将文件夹名称附加到文件，如 abc_01-01-20.txt。但是 root->01-01-20 里面有可能包含子文件夹 (Details) 并且里面的文件名可能相同。因此，如果文件不存在于 01-01-20 文件夹中，则它有可能存在于“Details”文件夹中。如果 "abc.txt" 存在于 父文件夹 上，则脚本不应查看子文件夹（Details）。

TargetDir->abc_01-01-20.txt
TargetDir->abc_01-02-20.txt
..
..
TargetDir->abc_12-31-20.txt

这是我构建的脚本

$Source = "\Server01\root"
$SrcFile="abc.txt"
$GetSrcFile = Get-ChildItem $Source | Where-Object {$_.name -like "$SrcFile"}
$Destination = "C:\Target"
Copy-Item "$Source$GetFile" "$Destination" -Force -
Confirm:$False -ErrorAction silentlyContinue
if(-not $?) {write-warning "Copy Failed"}
else {write-host "Successfully moved $Source$SrcFile to $Destination"}

问题是此脚本无法提取文件夹名称并将其附加到文件。

我没有对此进行测试，但我认为您的代码存在一些问题。您似乎混淆了来源和目的地。此外，您正在将文件收集到变量 $ScrFile 中，但您没有以可以确定新名称的方式对其进行迭代...

我很快就完成了这个并且没有测试它但是作为一个你如何完成它的示例它可能是一个起点。

$Source      = "\Server01\Destination"
$SrcFile     = "abc.txt"
$Destination = "C:\Source\rootdir"

# Note: this can be done with other ForEach permutations as well.

Get-ChildItem $Source -File | 
Where-Object{ $_.Name -match $SrcFile } |
ForEach-Object{
    # Get the name of the dir you found the file in:
    $ParentDirectory = Split-Path $_.DirectoryName -Leaf 
    
    #calculate a new file name including the directory it was found in:
    $NewFileName     = + $_.BaseName + $ParentDirectory + $_.Extension
    
    #Join the new name with the directory path you want top copy the file to
    $NewFileName     = Join-Path $Destination $NewFileName 
    
    # Finally try and copy the file.  Use try catch for more robust error handling
    Try{
        Copy-Item $_.FullName $NewFileName -ErrorAction Stop
        Write-Host -ForegroundColor Green "Successfully copied the file..."
    }
    Catch{
        # You can do a better job here...
        Write-Host -ForegroundColor Red "There was an error copying the file!"
    }
}

我认为您有点混淆了源和目标。为此，您需要递归地获取 abc.txt 文件，并且仅当直接父文件夹的名称类似于日期时，使用新名称复制文件：

$Source      = 'C:\Source\rootdir'       # rootfolder where the subfolders with files are
$Destination = "\Server01\Destination"  # path to where the files need to be copied

if (!(Test-Path -Path $Destination -PathType Container)) {
    $null = New-Item -Path $Destination -ItemType Directory
}

Get-ChildItem -Path $Source -Recurse -Filter 'abc.txt' -File | 
    Where-Object {$_.DirectoryName -match '\\d{2}-\d{2}-\d{2}$'} | 
    ForEach-Object {
        $newName = '{0}_{1}{2}' -f $_.BaseName, ($_.DirectoryName -split '\')[-1], $_.Extension
        $target  = Join-Path -Path $Destination -ChildPath $newName
        try {
            $_ | Copy-Item -Destination $target -Force -Confirm:$false -ErrorAction Stop
            Write-Host "File '$($_.Name)' copied to '$target'"
        }
        catch {
            Write-Warning "Error: $($_.Exception.Message)"
        }
    }
