如何过滤掉 powershell 中的信息？

Question

How can I filter out information in powershell?

For instance, i run system info on a remote machine, I would write:

systeminfo -s <computerName>

However how can i do this for many machines and also how can I filter out the information?

I want to search many machines for just "Total Physical Memory"

As suggested by @Lee_Daily, it would be easier and more direct to use Powershell.

This will produce the amount of physical memory in GiB.
