如何在Windows PowerShell腳本中使用創建日期時間早於90天的文件進行計數？

Question

我要求從包含多個子文件夾的整個目錄中獲取比90天更舊的文件。 我嘗試下面的腳本，但沒有運氣。

dir Z:\EDI\ |
    ? {$_.CreationTime -ge (Get-Date).AddDays(-90) -and !$_.PsIsContainer} |
    group {$_.CreationTime.ToShortDateString()} |
    select Name, Count

這是獲取信息的另一種方式。 [ 咧嘴 ]

它使用日期數學來獲取以天為單位的年齡並將其與允許的最大值進行比較。 然后將其放在自定義對象中，以后可用於獲取詳細信息。

$MaxAgeInDays = 90
$Today = (Get-Date).Date
$SourceDir = $env:TEMP

$TooOldFileList = Get-ChildItem -LiteralPath $SourceDir -File -Recurse |
    Where-Object {($Today - $_.CreationTime).Days -ge $MaxAgeInDays} |
    Sort-Object CreationTime |
    ForEach-Object {
        [PSCustomObject]@{
            AgeInDays = ($Today - $_.CreationTime).Days
            FileName = $_.FullName
            }
        }

$OldestFile = $TooOldFileList |
    Select-Object -First 1

''
'Max allowed age in days = {0, 5}' -f $MaxAgeInDays
'Number of too-old files = {0, 5}' -f $TooOldFileList.Count
'Oldest file age in days = {0, 5}' -f $OldestFile.AgeInDays
'Oldest file name        = {0}' -f $OldestFile.FileName

輸出...

Max allowed age in days =    90
Number of too-old files =   296
Oldest file age in days =  1136
Oldest file name        = C:\Temp\FXSAPIDebugLogFile.txt
