Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Bashing the Bash – Replacing Shell Scripts with Python
I wrote this to simplify just that for my own tools; the subprocess module that comes with the batteries has a very general interface, i think that it is a bit complex for a quick script.

https://pypi.org/project/subb/
Python doesn't have the problem of shell scripting language, it doesn't get impractical, as the program is getting more complex. In bash you have arrays, and even maps, but these aren't pretty. Also the shell scripting language is being evaluated by an parse tree/AST interpreter, that's significantly slower than even python, in it's byte code interpreted form.
My objective was to get an abstraction, for a one line process run and extraction of the result, similar to what we had in Perl5 with the system library function. https://perldoc.perl.org/functions/system
Also the shell is impractical, when it comes to slightly more complex programs. There is a limit on what you can do with pipes. Maybe that's the reason why perl is that flexible, as they tried to bridge both realms: Perl had to be useful as a replacement for the quick shell like script, and to be useful as a general purpose programming language.

Acme.sh runs arbitrary commands from a remote server
I usually replace shell scripts with python (using sh module: https://amoffat.github.io/sh/ for calling other scripts/programs).

The Right Way to Run Shell Commands from Python
> sh relies on various Unix system calls and only works on Unix-like operating systems - Linux, macOS, BSDs etc. Specifically, Windows is not supported.

Anyone have any tips for developing on Windows?
You can even run interpreted languages as a shell. See plumbum or sh for ways to make it a more comfortable shell and ipython for a better version of the shell.

Argbash – Bash Argument Parsing Code Generator
100% agree. There are some libraries like https://amoffat.github.io/sh/ that aim to make that easier, but they always have some quirks that, funnily enough, are often the corner cases you were hitting in your complicated Bash script in the first place.

Unix bash scripting versus Python - any resources out there for comparisons?
Another way to make Python scripts nicer is to use https://github.com/amoffat/sh
