Writing bash scripts is really not that difficult - despite what folks might want to convince you of.
ShellCheck is a great tool, yes, and can be run natively inside your IDE. Just like any language, you need to learn the language and learn it's tools.
Blanket statements like "write all your scripts in python because there's less bugs" really just means the commenter is more familiar with python. Do enough script writing and you'll realize how absurd that statement is.
It's a lot like the folks that scream nobody should ever write a single line of C or C++ because it's "dangerous" - yet untold number of lines of C/C++ are written every day. A pencil can be dangerous in the wrong hands...
Well I use both extensively, and I'm very confident that I can write a script of 1000 lines with much less bug and much better error handling that in bash, in half the time it would take me.
In fact, as soon as you need to use arrays, it's game over.
