At work I regularly have to support 500+ line scripts written by random developers, I 'n hate them.
Yeah I think that most people would hate this situation too compared to, say, similar scripts written in Python. But as parent said, the wrong tool for the wrong job is rarely a pleasant experience.
Bash scripts are generally very short. If you need unit tests and a debugger you probably should be using something other than Bash. But saying you hate the shell because it's bad at something it was never designed for is silly.
