Alternatively, you could just spawn a separate shell (with "bash")
before setting any of the GRASS environment variables then terminate
it (with "exit") when you're finished.

A child process (normally) inherits its environment from its parent at
start-up, but any changes to the child's environment won't affect the
parent's.
