如何刪除x天以前的文件？

Question

我想刪除比x天更早的文件，在下面的例子中是5。我試圖在下面使用，但它不工作，也不會拋出錯誤。

Get-ChildItem –Path 「E:\del」 –Recurse | Where-Object{$_.CreationTime –lt(Get-Date).AddDays(-5)} | Remove-Item 

Answer 1

這是您可以採取的方法。

$Path = E:\del 
$DaysBack = "-5" 
$CurrentDate = Get-Date 
$DatetoDelete = $CurrentDate.AddDays($DaysBack) 

#delete files from $Path directory that are older than $Daysback 
Get-ChildItem -Path $Path -Include * -Recurse | Where-Object {$_.LastWriteTime -lt $DatetoDelete} | Remove-Item -ErrorAction SilentlyContinue -Recurse -Force 

Answer 2

試試這個：

$cleanup_days = 5 
$cleanup_lastWrite = $now.AddDays(-$cleanup_days) 

Get-ChildItem -Path "E:\del" | Where-Object { $_ -is [System.IO.FileInfo] } | ForEach-Object { 
    If ($_.LastWriteTime -lt $cleanup_lastWrite) 
    { 
     Remove-Item $("E:\del\" + $_) 
    } 
}
