Get-PathVariable [[-Scope] <String>] [<CommonParameters>]
DESCRIPTION
Use this command to test the locations specified in the %PATH% environment variable. On Windows platforms, you can distinguish between settings set per machine and those set per user. On non-Windows platforms, the scope will be Process.
