Question

我正在为我的客户制作磁盘空间脚本。我刚刚使用ISE对它进行了测试，看起来它一直工作，直到我检查了成绩单。

在第32行的第一个删除周期中有一些部分正在删除C：\ Windows \ System32 \中的文件，这当然我不想要它。我确信我做错了什么，但我检查过拼写错误，我不明白如何从用户目录中获取％system32％。

If (([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([System.Security.Principal.WindowsBuiltInRole]::Administrator))
    {
        $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + ' (Elevated)'
        $Host.UI.RawUI.BackgroundColor = 'DarkBlue'
        Clear-Host
    }
Else
    {
        $newProcess = New-Object Diagnostics.ProcessStartInfo 'PowerShell'
        $newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"
        $newProcess.Verb = 'runas'
        [Diagnostics.Process]::Start($newProcess) | Out-Null
        exit
    }

第32行是Get-ChildItem | Remove-Item -Recurse -WhatIf

Answer 1

您的代码中应该调整几项内容，但现在遇到的问题是您没有指定??。因此-Path将从工作目录返回项目！

Get-ChildItem

应该是

 Get-ChildItem | Remove-Item -Recurse -WhatIf

就像我说的那样，有几个潜在的陷阱和改进领域有待解决。你使用相同的循环5次。一对夫妇完全一样。

Answer 2

我认为问题出在第23行，其中代码没有使用完整路径名填充数组。有关如何获取完整路径名的一些建议，请参阅Get full path of the files in PowerShell。
