I suppose my main bash script on BSD, ~400 lines for backup, compilation and other admin tasks including a portable static text/plain web server have never failed me but never tested them interchangeably, so, prone some truth to failure.

I am not disagreeing of course and I would agree, Bash is designed for the system functions and that this is niche. However if it's all you got, eh, go for it.

Systems admin for 15 years and have handled some very hosed systems. Maybe the python binary got hosed and you were really desperate to share your lasagna recipe with your mother and the internet, it does have a purpose. Not ideal, sure.
