As a person who’s been doing shell programming for 35 years and Python for 15 years, I completely disagree.

Bash scripts and Bash control flow has been and is used in highly critical scripts all over the place, including other planets.

We’ve been writing reliable, well-designed scripts for many decades. Some of my scripts are several hundred lines long and older than the system engineers currently occupying their positions.

Python is fine too. Use the right tool for the right job.
