Obviously, but at one point I sat down and tried to estimate how much time I wasted on using `set -euo pipefail` in my scripts and still having to chase after silent failures. I might be biased at this point but it still seemed quite a lot.
For a lot of one-off tasks shell scripting is 90% superior (unless you are super comfy with Golang) because it takes literal minutes to write and then iterate on it. Sure. But my threshold for when to reach for a proper program has been getting lower and lower lately because I very quickly arrive at a point where I need typing, better error-handling, retries and a few others.
Not everyone's case, surely. It seems my journey was more along the lines of "I was using shell scripting much more than I had to and I am making a partial comeback to proper programs".
