Re: $*&$*&
Bit baffled myself. I'm reading it as: run the script's run-time commandline parameters in background, then copy them again to the commandline minibuffer and then.... type a meaningless dollar sign (AKA syntax error).
At best, requires you to enter a valid command after the script name when invoking it.
Unless there's some new Linux bash oddity?
Vs: while true; do; fork; done.
