Powershell还原文件的先前版本

Question

We got hit by virus, it changed all common file extension to .kmybamf (.txt >> .txt.kmybamf ) and if I delete .kmybamf , the file got damaged.....

So I made a list of all files that got damaged. now I'm trying to overwrite them by previous version. Anyone knows how to do it in Powershell?

I can do it in cmd similar to this

subst X: \localhost\D$\@GMT-2011.09.20-06.00.04_Data
robocopy Z: D:\Folder\ /E /COPYALL

But I want to do it in one shot in Powershell, It has to be a "if .kmybamf found, then restore previous version." and powershell seems like has no such cmdlet for restoring previous version of files or folders.

Answer 1

$fileList = Get-Content -Path "\\localhost\D$\@GMT-2011.09.20-06.00.04_Data"
$destinationFolder = "D:\Folder\"

foreach ($file in $fileList)
{
    Copy-Item -Path $file -Destination $destinationFolder -Force
}

This will also work but I find it less readable

Get-Content -Path "\\localhost\D$\@GMT-2011.09.20-06.00.04_Data" | ForEach-Object { Copy-Item -Path $_ -Destination "D:\Folder" -Force }

Get-Content用于从文件中读取文本，从文件夹中读取文件，您必须使用Get-Childitem
