Question

我试图创建一个PowerShell脚本，它将列出包含文件和子目录的所有目录，这些脚本在90天内未被修改。我不是一个经验丰富的脚本编写者，所以我四处搜索并找到了下面的脚本。

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objStartFolder = objFSO.GetFolder("C:\Scripts")
Set colFiles = objStartFolder.Files

i = 0

For Each objFile in colFiles
    dtmDate = objFile.DateLastModified
    intAge = DateDiff("d", dtmDate, Date)

    If intAge < 90 Then
        i = 1
        Exit For
    End If
Next

If i = 0 Then
    Wscript.Echo objStartFolder.Path
End If

ShowSubfolders(objStartFolder) 

Sub ShowSubFolders(Folder)
    For Each objSubfolder in Folder.SubFolders
        Set objFolder = objFSO.GetFolder(objSubFolder.Path)
        Set colFiles = objFolder.Files

        i = 0

        For Each objFile in colFiles
            dtmDate = objFile.DateLastModified
            intAge = DateDiff("d", dtmDate, Date)

            If intAge < 90 Then
                i = 1
                Exit For
            End If
        Next

        If i = 0 Then
            Wscript.Echo objSubfolder.Path
        End If

        ShowSubFolders objSubfolder
    Next
End Sub

太棒了，所以我在我的Windows系统上运行它，但它返回以下错误：

Missing opening '(' after keyword 'for'.
At F:\find.ps1:8 char:5
+ For  <<<< Each objFile in colFiles
    + CategoryInfo          : ParserError: (OpenParenToken:Token
    + FullyQualifiedErrorId : MissingOpenParenthesisAfterKeyword

我玩过它，猜测如何/在哪里添加＆＃34;（＆＃34;但我真的无法到达任何地方。

使用Get-ChildItem cmdlet在PowerShell中可以更加简洁：

递归：

$Filter = {$_.LastWriteTime -lt (Get-Date).AddDays(-90)}
$OldStuff = Get-ChildItem "C:\your\base\dir" -File -Recurse | Where-Object $Filter

或者只是文件夹及其直接子文件夹（如示例所示）：

$Filter = {$_.LastWriteTime -lt (Get-Date).AddDays(-90)}
$OldStuff = Get-ChildItem "C:\your\base\dir" -File | Where-Object $Filter
$OldStuff += Get-ChildItem "C:\your\base\dir" -Directory | ForEach-Object {
    Get-ChildItem "C:\your\base\dir" -File | Where-Object $Filter 
}

在2.0版中，Get-ChildItem cmdlet没有-File参数。您可以使用Where-Object来测试该项目是否为文件夹（使用PsIsContainer属性）：

递归：

$Filter = {-not($_.PsIsContainer) -and ($_.LastWriteTime -lt (Get-Date).AddDays(-90))}
$OldStuff = Get-ChildItem "C:\your\base\dir" -Recurse | Where-Object $Filter

文件夹及其直接子文件夹：

$Filter = {-not($_.PsIsContainer) -and ($_.LastWriteTime -lt (Get-Date).AddDays(-90))}
$OldStuff = Get-ChildItem "C:\your\base\dir" | Where-Object $Filter
$OldStuff += Get-ChildItem "C:\your\base\dir" |Where-Object {$_.PsIsContainer}| ForEach-Object {
    Get-ChildItem "C:\your\base\dir" | Where-Object $Filter 
}

列出非活动目录
