库存系统Java和Powershell

我正在为由多台计算机和服务器组成的网络制作系统库存程序 . 因此，我发现服务器更智能，更容易放置代码，以检查本地计算机上是否有任何新信息：

Powershell将作为登录脚本运行并获取所需的所有信息，然后将其与旧信息进行比较 .

就在那时我开始问你聪明人的问题 . 截至目前，我正在比较新旧信息：

• Powershell收集所有数据并将其写入.txt文件

• Powershell将新制作的"cacheInfo.txt"与"SystemInfo.txt"进行比较

这是一个不必要的联合......我希望..

有没有办法在powershell中比较这样的信息而不制作附加文件？

这是powershell的信息收集命令：
