Suppose I go into the System Properties window and add an environment variable to the Path. If I have a terminal window open, it will be unaware of the change, so I close it and open another one.
Is there a way to have it reload the Path information from the command line? I'd particularly like to know how I can do it with my Cygwin shell, but I'd be happy to know how to handle either case (Cygwin or native terminal).
