What happens if I try to run your script on my hypothetically
different machine in a different shell, where bash might be located in
/usr/thisisnothebinyourelookingfor/bash?

Would it depend on the smarts behind the shell I'm running as to
whether it processes it as bashscript or not?
Is there some standard naming service which can resolve program
locations? Do we need one?

I ask this, because some people say you should obfuscate your sbin and
bin locations for security reasons. Does this mean going through the
headaches of failed scripts unless you're careful?
