我对 PowerShell 还是很陌生,如果我有一些要求,我现在会做什么,我会在网上搜索并将代码修改为我需要的。
现在,我正在尝试从我们的服务器中提取 RDP 用户登录信息。我设法获得了一些代码,对其进行了更新,以便我可以通过调用命令远程运行它。但是,我对其中一个变量有疑问,其中如果我输入一个日期值,例如 2019 年 9 月 1 日或 2019 年 9 月 1 日,则脚本可以工作。但是如果我使用 (Get-Date).AddDays(-7),它就行不通了。昨天整个下午我一直在测试这个脚本,而对于我的生活,我仍然无法让它工作:(
这是我遇到问题的代码部分:
#$StartDate = (Get-Date).AddDays(-7).ToString("dd-MMM-yyyy") #--> does not work
#$StartDate = (Get-Date).AddDays(-7) #--> does not work
#$StartDate = "1-Sep-2019" #--> Works
$StartDate = "9/1/2019" #--> Works
这是我正在测试的完整脚本。感谢有人可以就如何在不使用静态日期的情况下完成这项工作提供一些提示。在此先感谢您的帮助!
