Question

我在名为D:\TestARC_Source的目录中有数百个excel文件，如下所示：

5020190429.dat
5120190429.dat
602019111121.dat
702019050926.dat 
etc.

我需要一个脚本，根据文件名的前两个字符将其移动到相应的文件夹中。文件夹已在目标目录上创建。

D:\TestARC_Destination\file_50
D:\TestARC_Destination\file_51
D:\TestARC_Destination\file_60
D:\TestARC_Destination\file_70

文件应基于文件名的前两个字符移动到相应的文件夹。例如，5020190429.dat移至50_file文件夹。

我正在尝试编辑以下脚本，但无法正常工作。我对PS脚本知之甚少，如果您能帮助我，我将不胜感激。

$SourceFolder = "C:\Users\Administrator\Desktop\ARC_Testing\TestARC_Source\"
$targetFolder = "C:\Users\Administrator\Desktop\ARC_Testing\TestARC_Destination\"

# Find all files matching *.sql in the folder specified
Get-ChildItem -Path $SourceFolder -Filter *.dat | ForEach-Object {

    # Combine the source filename and target directory
    # The source filename has all instances of _ replaced with \
    # Cast the resulting string to a FileInfo object to take advantage of extra methods
    [System.IO.FileInfo]$destination = (Join-Path -Path $targetFolder -ChildPath $_.Name.replace("_","\"))

    # Create the directory if it doesn't already exits
    if (!(Test-Path) $destination.Directory.FullName)
    { 
        New-item -Path $destination.Directory.FullName -ItemType Directory 
    }

    # Copy the source to the target directory
    copy-item -Path $_.FullName -Destination $Destination.FullName 
}

Answer 1

以下内容应根据您的条件移动文件。如果您对要移动的内容感到满意，请删除-WhatIf开关。

$Source = "D:\TestARC_Source"
$Dest = "D:\TestARC_Destination"

$FilesToMove = Get-ChildItem -Path $Source -File -Recurse -Filter "*.dat" -Include "[0-9][0-9]*"

Foreach ($file in $FilesToMove) {
    Move-Item -Path $file -Destination "$Dest\File_$($file.basename.substring(0,2))” -WhatIf
}

Answer 2

一种有效的方法是按前两位数字对文件进行分组，
检查文件夹是否存在（并在必要时创建），然后一次性移动文件。

volume_prices.loaded?       # should return true
volume_prices.count         # should return 0
volume_prices.length        # should return 1
volume_prices.reload.length # should return 0

使用上述测试数据运行后的树：

## Q:\Test\2019\05\31\SO_56397901.ps1
$SourceFolder = "C:\Users\Administrator\Desktop\ARC_Testing\TestARC_Source\"
$targetFolder = "C:\Users\Administrator\Desktop\ARC_Testing\TestARC_Destination\"

Get-ChildItem -Path "$SourceFolder[0-9][0-9]*" -Filter *.dat | 
   Group-Object {"file_"+$_.BaseName.Substring(0,2)}| ForEach-Object {
      $TargetDir = Join-Path $targetFolder $_.Name
      if(!(Test-Path $TargetDir)){MD $TargetDir | Out-Null}
      $_.Group.FullName | Move-Item -Destination $TargetDir #-WhatIf
}
