> Bash scripts should be simple glue between programs
If a script is literally just running a list of commands and occasionally piping the output from one to another, you may as well make it POSIX compliant (therefore a sh script) since you're not using any features of Bash anyway.
> But I always feel that if you reach a certain complexity in your bash scripts, you should rather pivot to any other $lang.
This is a common critique, but what other lang?
I make Bash scripts all the time for system administration tasks, and they largely just werk™ as long as you have Bash (90% of the time pre-installed) and the necessary commands. From there, any command can be readily called, piped, or saved to variables/arrays, and Bash has powerful (enough) native math and string manipulation capabilities.
Meanwhile with Python there's always some hassle installing dependencies with pip(x) and virtual environments, plus the unfortunate rare Python 2 encounter where you either gotta rewrite the whole thing in python 3 or figure out how to install the old Python 2 runtime and 3rd party python 2 libraries used in the script on your distro.
I don't see the appeal of sonething like the OP though. I can't imagine the "precompiled" scripts are so much more readable its worth the incomprehensible mess it appears to generate with the "compiled" script.
I have to agree. Bash works fine in its environment, and while there are times when another language might be more appropriate for whatever reason, Bash works. I can run it on any box I have access to and if I stay away from utils that aren't preinstalled, I don't need to worry about dependencies. I've found that python is far more version and dependency driven.

Why are people so afraid of Bash?
