The advantage of using a subshell is that you don't need to copy-and-paste the output, because it gets put into the right place automatically. As long as there's no special shell quoting that has to be handled, everything Just Works. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
