Question

我在服务器上有一条路径，每天以YYYYMMDD格式创建FILES。（20120618.TXT等）

示例文件 APP20161009.TXT APP20161008.TXT APP20161110.TXT

$YourDirectory = "C:\Temp\"

$Threshold = ((get-date).adddays(-2))

ForEach ($FileName in $CleanupList) {
    $date = ([datetime]::ParseExact((($FileName.Name.TrimEnd(".txt")).Substring($FileName.Name.Length - 12)), "yyyyMMdd", $null))
    if ($date -lt $Threshold) {
        Remove-Item $Filename.FullName -Force
    }
}

Answer 1

目标似乎不是删除目录或文件。以下代码假设自＆＃34; .txt＆＃34;以来的文件。例子表明。

[cmdletbinding()]
Param()

$YourDirectory = ".\t"
$Threshold = (get-date).adddays(-0)
$CleanupList = Get-ChildItem -File $YourDirectory |
    Where-Object {($_.Name -match 'APP\d{8}.txt') -and ($_.LastWriteTime -lt $Threshold)}

if ($CleanupList -ne $null) {
    ForEach ($FileName in $CleanupList) {
        Write-Verbose $FileName
        Write-Verbose $FileName.FullName
        Remove-Item -WhatIf $FileName.FullName -Force
    }
}

PowerShell如何按文件名删除设置为日期的文件（testeYYYYMMDD.txt）？
