bash is a pitfall. In this world of IAC, powerful tools, unit testing, CICD, well crafted languages and libraries its a relic of an old time long gone.
there's just no way we should all be scripting in a language where typing out anything more than a single command necessitates a cascade of "well ACKshually it should be done this way" corrections, whether it's from a static analysis tools or your grey-bearded Bash-wizard coworkers.
We are eventually going to look at using bash and similar shells for scripting as the bad old days.
If there is only one correct answer to a problem in a given language, people will shunt that creativity to architecture or elsewhere. People still want to be creative in their work, programming and system administration is fundamentally a creative job.
Which would you rather have, a script that was too clever by half, or a system architecture that was too clever by half?
It's a whole lot easier to fix the script than it is the system architecture.
So - if people instead could use a shell/script language that offers some more correctness/guarantees or fewer pitfalls, they will subconsciously make bugs in the system outside of that script because creativity?
If they dont get to be creative in solving the problem - if their job is simply to be a human emitter of YAML, then that creativity will be spent elsewhere.
Not sure how we got from wishing we could use a language with fewer footguns than bash to… human emitter of YAML whose creativity has been ripped from them, so they will now design overly-clever systems as some sort of creative outlet?
and still it's the only one which is easily available everywhere and for the most part already in the allow/whitelist of tooling in most organizations as redhat and debian/ubuntu are almost everywhere.
But practically everything unixy supports some shell variant that's similar to the others, so we have no choice in the matter. I compare this to PHP. They're both bad, PHP is a choice.
