# These snippets provide a quick way to update your environment variables
# directly from your powershell console. Just copy paste these lines, or
# even better, add it to your profile as functions.

# refreshing env in current shell
$env:path = [System.Environment]::GetEnvironmentVariable("Path", "Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path", "User")

# adding path to env
# set path in the $_newPath variable, and it'll get set to your user environment path and persisted.
$_newPath=""; [System.Environment]::SetEnvironmentVariable("Path", [System.Environment]::GetEnvironmentVariable("Path", "User") + ";${_newPath}", "User")
