powershell - Powershell:记录我删除的文件

Question

Powershell的新手，需要一些帮助。我的脚本搜索TEST文件夹和子文件夹，然后删除21天以上的文件。我想将所有已删除的文件记录在日志文件中。

cls 
$Now = Get-Date 
$Days = "21" 
$Targetfolder = "c:\TEST" 
#----- define LastWriteTime parameter based on $Days ---# 
$LastWrite = $Now.AddDays(-$Days) 
#----- get files based on lastwrite filter and specified folder ---# 
$Files = Get-Childitem $TargetFolder -Include $Extension -Exclude *.xml -Recurse | where { $_.LastWriteTime -le "$LastWrite" } 
foreach ($File in $Files) { 
    if ($File -ne $Null) { 
        write-host "Deleting File --> $File" -ForegroundColor "Green" 
        Remove-Item $File.FullName | out-null 
    }
}

Answer 1

Add-Content $filename $value可以做到!

cls 
$Now = Get-Date 
$Days = "21" 
$Targetfolder = "c:\TEST" 
$LogFile = "C:\DeletedFiles.txt"
#----- define LastWriteTime parameter based on $Days ---# 
$LastWrite = $Now.AddDays(-$Days) 
#----- get files based on lastwrite filter and specified folder ---# 
$Files = Get-Childitem $TargetFolder -Include $Extension -Exclude *.xml -Recurse | 
        where {$_.LastWriteTime -le "$LastWrite"} 
        foreach ($File in $Files) { 
            if ($File -ne $Null) { 
                Add-Content $LogFile $File.FullName
                write-host "Deleting File --> $File" -ForegroundColor "Green" Remove-Item $File.FullName | out-null 
            } 
        } 

如果要使其更健壮，可以向文件添加时间戳，以便知道何时删除文件。

$myDate = get-date -format -g
$content = $myDate  + "   " + $File.FullName
Add-Content $LogFile $content
