Ouch. I know the feeling. Is your thinking: If they can program in Bash, they have learned how to program in many other languages, and Bash is their glue to make stuff "schedulable" via crontab, (dreaded) AutoSys, k8s, etc.? For me, learning how to program /OK/ in Bash has been a very difficult journey -- as difficult as Perl and Python, due to insanely weak typing. You are always fighting unknowns when you receive some function parameters.
