PowerShell复制文件夹中的所有文件和不超过300分钟的Sub=Folders
PowerShell复制文件夹中的所有文件和不超过300分钟的Sub=Folders
提问于 2022-04-28 11:58:21
我试图复制文件夹和子文件夹中的所有文件，但我得到的代码只复制主文件夹中的文件，它不复制子文件夹中的文件。在目的地，我不想维护原始文件的文件夹结构，我只想把所有原始文件放在一个特定的目标文件夹中。这是我的代码：
Powershell -NoL -NoP -C "&{$ts=New-TimeSpan -M 300;"^
"Get-ChildItem "C:\Origin" -Filter '*.dat'|?{"^
"$_.LastWriteTime -gt ((Get-Date)-$ts)}|"^
%%{Copy-Item $_.FullName 'C:\Destination'}}"有人能帮帮我吗？提前谢谢。

这里有一个修改过的脚本，您可以将其保存为"Copy-Unique.ps1“，您可以从批处理文件中运行。
function Copy-Unique {
# Copies files to a destination. If a file with the same name already exists in the destination,
# the function will create a unique filename by appending '(x)' after the name, but before the extension.
# The 'x' is a numeric sequence value.
[CmdletBinding(SupportsShouldProcess)] # add support for -WhatIf switch
Param(
[Parameter(Mandatory = $true, ValueFromPipeline = $true, Position = 0)]
[Alias("Path")]
[ValidateScript({Test-Path -Path $_ -PathType Container})]
[string]$SourceFolder,
[Parameter(Mandatory = $true, Position = 1)]
[string]$DestinationFolder,
[Parameter(Mandatory = $false)]
[int]$NewerThanMinutes = -1,
[Parameter(Mandatory = $false)]
[string]$Filter = '*',
[switch]$Recurse
)
# create the destination path if it does not exist
if (!(Test-Path -Path $DestinationFolder -PathType Container)) {
Write-Verbose "Creating folder '$DestinationFolder'"
$null = New-Item -Path $DestinationFolder -ItemType 'Directory' -Force
}
# get a list of file FullNames in this source folder
$sourceFiles = @(Get-ChildItem -Path $SourceFolder -Filter $Filter -File -Recurse:$Recurse)
# if you want only files not older than x minutes, apply an extra filter
if ($NewerThanMinutes -gt 0) {
$sourceFiles = @($sourceFiles | Where-Object { $_.LastWriteTime -gt (Get-Date).AddMinutes(-$NewerThanMinutes) })
}
foreach ($file in $sourceFiles) {
# get an array of all filenames (names only) of the files with a similar name already present in the destination folder
$destFiles = @((Get-ChildItem $DestinationFolder -File -Filter "$($file.BaseName)*$($file.Extension)").Name)
# for PowerShell version < 3.0 use this
# $destFiles = @(Get-ChildItem $DestinationFolder -Filter "$baseName*$extension" | Where-Object { !($_.PSIsContainer) } | Select-Object -ExpandProperty Name)
# construct the new filename
$newName = $file.Name
$count = 1
while ($destFiles -contains $newName) {
$newName = "{0}({1}){2}" -f $file.BaseName, $count++, $file.Extension
}
# use Join-Path to create a FullName for the file
$newFile = Join-Path -Path $DestinationFolder -ChildPath $newName
Write-Verbose "Copying '$($file.FullName)' as '$newFile'"
$file | Copy-Item -Destination $newFile -Force
}
}
# you can change the folder paths, file pattern to filter etc. here
$destFolder = Join-Path -Path 'C:\Destination' -ChildPath ('{0:yyyy-MM-dd_HH-mm}' -f (Get-Date))
Copy-Unique -SourceFolder "C:\Origin" -DestinationFolder $destFolder -Filter '*.dat' -Recurse -NewerThanMinutes 300将代码更改为现在使用一个datetime对象来进行比较，而不是以分钟为单位进行比较。这也许会使代码更容易理解，但肯定会更灵活。

}
}
# you can change the folder paths, file pattern to filter etc. here
$destFolder = Join-Path -Path 'D:\Destination' -ChildPath ('{0:yyyy-MM-dd_HH-mm}' -f (Get-Date))
Copy-Unique -SourceFolder "C:\Origin" -DestinationFolder $destFolder -Filter '*.dat' -Recurse -NewerThan (Get-Date).AddMinutes(-300)当您保存了上面的代码，让我们说'C:\Scripts\Copy-Unique.ps1‘之后，您可以从一个批处理文件中调用它，如下所示：
