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?
Exact same story here. Bash -> Python -> Rust.
Generally speaking, people should settle on a compiled language if they can. They can iterate as fast as interpreted languages these days.
Edit: If you want to try something different in scripting, try the execline language. Its interpreter processes the script and exits immediately even before the script execution begins. Traditional shell interpreters (like bash) stay active till the entire script is finished. Execline achieves this by a clever chaining of Unix execs, forks and variable substitutions. This makes execline scripts lighter (useful in embedded systems), more secure and less error-prone than traditional scripts. The downside is that writing them will feel a bit weird - since the fundamental paradigm is different from regular shells. However, that will be a refreshing change if you're someone who likes to experiment and try new things.
Yes, and Rust with incremental compilation is pretty fast to iterate as well, as long as you don't use massive libraries/build-scripts etc.
