parallel bash scripts

[bruce]

HI Mateusz

Yeah, tried the basic "&" ... but the issue is the shell scripts run
as infinite loops.. and therefore, the dog.sh doesn't really
exit/complete.

So I can't really run them sequentially.

If I open up separate term/windows, then of course, I can manually run
them (one in each window)..

thanks
