Question

我正在构建PS脚本，以仅从特定日期开始从IIS smtp中继中选择死信（.bad）文件...

有了这部分代码，我得到了...

％_。LastWriteTime：术语'％_。LastWriteTime'不被识别为cmdlet，函数，脚本文件或可运行程序的名称。检查名称的拼写，或者是否包含路径，请确认路径正确，然后重试。

获取子项$ SourceFolder * .bad |哪里对象{$ _。LastWriteTime -eq 1/23/2019}

Answer 1

我不认为Get-Childitem可与Regex一起使用。您可能需要将结果与类似的内容链接在一起

Get-childitem $SourceFolder| where-object{$_.Name -match "*.bad"}| where-object{$_.Lastwritetime...}

Answer 2

以这种方式尝试您的用例，而不是如何设置日期字符串。

Clear-Host
Get-ChildItem -Path 'd:\temp\certs'

Answer 3

$path = 'your\path\'
$Time = (Get-date).AddDays(-6)
$pasttime = Get-Date $Time -Format MM/dd/yyy

(Get-ChildItem -Path $path -Filter *.bad).LastWriteTime |  Where-Object {$_.LastWriteTime -eq $pasttime }

或尝试：

(Get-Item -Path $path).LastWriteTime | Where-Object {$_.LastWriteTime -le $pasttime}

或者也许：

(Get-ItemProperty -Path $path).LastWriteTime | Where-Object {$_.LastWriteTime -le $pasttime}

错误：“％_。LastWriteTime无法识别为cmdlet的名称”
