如何修改这个powershell脚本，使其创建日期、时间和已删除或以前删除的所有文件的名称的日志?

Question

我想做一个PowerShell脚本，删除某个文件夹中任何类型的文件，当他们是7天的时候。我遇到的问题是创建一个日志文件，其中包含脚本运行时删除或先前删除的所有文件的日期、时间和名称。

我想知道是否有一种方法可以修改本页上的答案:https://stackoverflow.com/questions/12326171/powershell-script-to-delete-sub-folders-and-files-if-creation-date-is-7-days-bu?lq=1

我想这样，而不是发送电子邮件与报告，它将创建一个日志文件的所有文件删除的名称，时间和日期在文件夹中，我存储的脚本(请注意，我希望它每次附加日志文件，而不是覆盖它)。我很抱歉，因为我不知道如何编码，所以我一直在努力做这件事自己很长一段时间了，我一直在问问题，但似乎仍然无法让它工作。所以，如果有人能修改这个脚本，我将非常感激!谢谢你！

这是我对脚本所做的(如果它有帮助的话)，但它不起作用(我又不知道如何编码):

$report_items = @()
# set folder path
$dump_path = "C:FileDeleterAutoDeleteFilesInThisFolder"
# set min age of files
$max_days = "-7"
# get the current date
$curr_date = Get-Date
# determine how far back we go based on current date
$del_date = $curr_date.AddDays($max_days)
# get the sub directories
$sub_dirs = Get-ChildItem $dump_path | Where-Object {!$_.PSIsContainer }
$sub_dirs | % {
    if (Get-ChildItem $_.FullName -Recurse | Where-Object { $_.LastWriteTime -gt     $del_date } ) {
        $report_items += New-Object -Type PSObject -Property @{
            Time = Get-Date -f "hh:mm:ss"
            Message = "Skipping " + $_.FullName + " because it contains items newer     than " + $del_date
        }
    }
    else {
        Remove-Item $_.FullName -Recurse
        $report_items += New-Object -Type PSObject -Property @{
            Time = Get-Date -f "hh:mm:ss"
            Message = "Deleting " + $_.FullName + " because it contains no items newer     than " + $del_date
        }
    }
}
$report_items | out-file "C:FileDeleterPruningReport.txt"

Answer 1

应该这样做:

Get-ChildItem -Path "C:FileDeleterAutoDeleteFilesInThisFolder" -Filter *.torrent -Recurse | Where { $_.CreationTime -lt (Get-Date).AddDays(-7) } | %{Remove-Item -Force; if ($?) {"$(Get-Date -Format 'MM-dd-yy HH:mm:ss.ff')  $_.Name" | Add-Content 'C:FileDeleterPruningReport.txt'}}

(if ($?)块的原因是仅在文件删除成功时才写入日志条目—您不想假设它成功了。)

Answer 2

不那么简洁，但我是PowerShell中不要过度流水线的粉丝。

[String]                   $strBaseDir       = "c:temp";
[String]                   $strFileFilter    = "*.txt";
[Int]                      $intDayThreshold  = 7;
[System.IO.FileSystemInfo] $objFile          = $null;
[Int]                      $intLastWriteDays = 0;
[String]                   $strLogFileName   = "d:datayourlogfile.log";
Get-ChildItem -LiteralPath $strBaseDir -Filter $strFileFilter -Recurse | Where-Object{ ! $_.PSIsContainer } |
    Foreach-Object {
        $objFile = $_;
        $intLastWriteDays = [Math]::Round((New-TimeSpan -Start $objFile.LastWriteTime -End (Get-Date)).TotalDays);
        if ( $intLastWriteDays -ge $intDayThreshold ) {
            Write-Output -InputObject ( "{0:G} : Deleting file [{1}] with last write time of [{2:G}], which is [{3}] day(s) ago." -f (Get-Date), $objFile.FullName, $objFile.LastWriteTime, $intLastWriteDays ) | Add-Content -Path $strLogFileName -PassThru;
            $objFile | Remove-Item -Force -ErrorAction silentlyContinue;
            if ( ! $? ) {
                Write-Output -InputObject "ERROR : Failed to remove file." | Add-Content -Path $strLogFileName -PassThru;
                } #if
        } else {
            Write-Output -InputObject ( "{0:G} : Skipping file [{1}] with last write time of [{2:G}], which is [{3}] day(s) ago." -f (Get-Date), $objFile.FullName, $objFile.LastWriteTime, $intLastWriteDays ) | Add-Content -Path $strLogFileName -PassThru;
        } #else-if
        } #Foreach-Object
