Powershell and cmd environment variables

问题

I use a batch script to set some environment variables local to that shell. When I launch PowerShell from that command prompt, I was expecting those environment variables to be available in the PowerShell script. But I don't see that happening.

Can someone help me what I'm missing?

回答1:

Those environment variables should be there in PowerShell but you have to access them using the Environment provider e.g.:

$env:foo

where foo is the environment variable name.
