I've been struggling with a rather complex shell script, and it's becoming apparent that Bash might not be the best choice for this particular task. While I usually gravitate towards statically typed languages like Go or Rust, I've noticed that many people recommend alternative languages such as Lua or Python for scripting tasks.
I'm curious to know your opinions and experiences with scripting languages for larger or more intricate shell scripts. Have you ever encountered a situation where Bash just didn't cut it, and if so, which scripting languages did you turn to for a more effective solution? Are there any specific languages you found particularly suitable for debugging, testing, or handling complex logic in your shell scripts?
pyinvoke.
You can create quick and dirty CLIs, invoke shell commands, and have all of python available for things like parsing config files, getting and setting environment variables, and making remote REST calls.
Totally second this.
But I 'd like to recommend starting with subprocess module which is built-in. Then go ahead and see what the extensions have to offer... There are other that may come handy, like Typer from Tiangolo, and Fire from Google.
