That's why I plan on migrating all my shell scripts to Golang programs f.ex. using https://github.com/bitfield/script -- it already has a number of simulations of shell commands and I'd contribute others if I had the time.
sh / bash / zsh scripts are just fragile and that's the inconvenient truth. People who devised the shell interpreters had good intentions but ultimately their creations grew to a scope 1000x bigger than they intended, hence all the "do X but if Y flag is set then do Z... unless flag A is also set in which case do Y and part of Z".
It's horrendous and I seriously don't get what's so difficult in just coding these scripts in a programming language that provides single statically linked binaries (like Golang) and just distribute it with your images -- or run them in CI/CD and have init containers and never include them in the images in the first place.
Inertia, of course. But I'll be actively working against it until I retire.

We use saw to tail lambda log:
Many code reviews Upgrade code to respect new conventions. #111 ccoVeille posted on Apr 13, 2024 go.mod refers to 1.17, so we can use os.ReadFile and os.WriteFile instead of ioutil.ReadFile and ioutil.WriteFile that are now deprecated. We should use errors.As since go 1.13 otherwise any wrapped errors won't be caught. View on GitHub Use JSONL format for New Line Delimited JSON #112 ccoVeille posted on Apr 13, 2024 https://en.wikipedia.org/wiki/JSON_streaming View on GitHub receiver cleanup #522 ccoVeille posted on Apr 05, 2024 Refactor to use consistent parserState receiver Clean unused receivers View on GitHub Fix test helpers #523 ccoVeille posted on Apr 05, 2024 Test helpers should use t.Helper() This way if an error occurs it would be reported outside the helper View on GitHub
