Where did you get this from? Who told you that shell scripts must have a lifetime and can't be crucial for production? There is no such a thing as serious programming vs baby shell programming. There are just tools, that are means to an end, simple as that. If the tool sufficiently and efficiently does the job, there is no need to replace it with an 'actual' programming language.
