$env:<name> (such as $env:computername) will do the trick in powershell.
type "powershell get-help about_env -detail" for more info.
The "env:" syntax can be used for other purposes such as listing all the
variables:
dir env:
but for just referencing values the $env:<name> syntax is the way to go.

Greetings.
I am on windows 7 and am trying to run some batch commands, for which I need
to know what is the syntax to get at the value of an environment variable?
I try %PATH%, %PATH, and even $PATH like in unix, but it all fails to expand
the value of the variable.
Since power shell apparently supports such unix-esque names as ls and pwd, I
am perplexed how to get it to pick up arguments.
BTW:
echo $PATH
prints nothing, whereas the % signs just get passed through as if it is not
a special syntax, as in a dos window.
So I suppose I'll get rid of power shell and use the dos window where the
args are predictable.
Now in the time it took to type this I could have done that. Comments
welcome.
Thx.
