Powershell-从文件名创建一个文件夹,然后将该文件放在文件夹中 [英] Powershell - Create a folder from a file name, then place that file in the folder
问题描述
我有一个文件列表说...
I have a list of files say...
T123_Product_1.jpg
T123_Product_2.jpg
T123_Product_3.jpg
T456_Product_1.jpg
T456_Product_2.jpg
T456_Product_3.jpg
等等等,另外约900个文件
etc. etc. etc. for about 900 more files
我需要做的是根据第一个下划线之前的字符创建一个文件夹,但由于有多个文件,因此不再重复.
What I am needing to do is create a folder based on the characters before the first underscore, but to not repeat it since there are multiple files.
因此,在上面的示例中,我只需要两个名为T123和T456的文件夹.
So in the example above, I would only want two folders named T123 and T456.
然后,我需要脚本将适当的文件放置在文件夹中.
Then I would need the script to place the appropriate files in the folder.
我在此线程中找到了一些代码,但是它们并不能完全满足我的要求.
I had found some codes in this thread, but they don't exactly do what I'm looking for.
$Files = Get-ChildItem -Path 'C:\Info\AUGUST 2011\Checklists\' -Filter 'DET1__*'
$Files | ForEach-Object {
$FileFullName = $_.FullName
$TempFileName = "$($FileFullName).tmp"
$DestinationFileName = "$FileFullName\$($_.Name)"
Move-Item $FileFullName $TempFileName
New-Item -Path $FileFullName -ItemType Directory
Move-Item $TempFileName $DestinationFileName
}
有帮助吗?
推荐答案
这里最简单的方法是按照第一部分对文件进行分组,然后将其变为目录名.在典型的PowerShell管道方式中,这非常简洁:
The easiest way here would be to group the files by the first part, which will then become the directory name. In typical PowerShell pipeline manner this is fairly succinct:
Get-ChildItem -File | # Get files
Group-Object { $_.Name -replace '_.*' } | # Group by part before first underscore
ForEach-Object {
# Create directory
$dir = New-Item -Type Directory -Name $_.Name
# Move files there
$_.Group | Move-Item -Destination $dir
}
