Limiting internet access on machine through BASH
Okay, I have NO idea where to post this now. Please, if this is NOT relevant to this subreddit, could anyone direct me to an appropriate subreddit.
If anyone can solve it, I will be so grateful!
I am trying to limit internet on my maching from 8AM to 10PM via powershell. I used GPT to help.
So here are some commands that work
To create internet kill switch on laptop:
To kill internet on laptop (test to show that it work)
To enable internet on laptop (test to show that it works)
However, the following does not work. I assume that it doesn't work when the machine is off.
To UNblock internet at 8:00AM, task called "EnableInternet"
I tried to edit it so that it checks the time every minute. That way if the machine is turned on AFTER 8AM, it works. But the following does NOT work
Similar for blocking the internet at midday.
I bet there are other issues, Like if both commands even worked, maybe the internet would just switch on and off?
I am so lost here guys, let me know if you have any solutions.
Inb4 why not just remove the internet: I only need the internet between 8AM and midday.

How to kill a noscript after it runs awhile from another noscript
Hi,
I have a noscript that runs on startup that I will want to kill to run another one(later on) via cron.
Can't figure out how to kill the first noscript programatically.
Say the noscript is: ~/noscripts/default.sh
and I want to kill it, what is a predictable way to kill said noscript. I know of ps and pkill but I hit a wall. I don't know the steps(or commands?) involved to do this accurately.
Thanks in advance.

Code Optimization Suggestions Welcome
Howdy bash friends,
Inspired by the goodwork of people in the ZSA and ploopy communities I whipped together some improvements to the moonlander (keyboard) spin of the ploopy nano (trackball) BTU mod, and I wrote a little noscript and a systemd .service file that use the api ZSA made to manage communication between the trackball and my moonlander, so that moving the trackball activates a mouse layer on my keyboard,
Honestly it's pretty sweet, very snappy and responsive, but I was wondering if some bored soul with a deep knowledge of bash built-in's was willing to take a look and let me know if I missed some low-hanging fruit to optimize my code?

I made public an configuration and function framework I've been using in bash for quite some time already. Do check out :)
Constructive criticism very welcome. Basically what it has is templates and you can have loadable modules for your own functions. A lot can be achieved probably with aliases and some other tools, but I have had fun with this one.

Nix: Defining Dependencies with Flakes

If you want a declarative way to define dependencies, Nix Flakes is the best solution I’ve found.
Admittedly, some parts of Nix can be difficult for newcomers to grasp. However, Large Language Models (LLMs) and your favorite search engine support you.
Personally, I think it’s time to say "goodbye" to Makefiles and noscripts that manually install tools.
Should you install everything via Nix?
My approach is to install the base tools via Nix and then let language-specific package managers handle the version pinning:
Go: `go.mod` / `go.sum`
JS:
Ruby: `Gemfile` / `Gemfile.lock`

Is there a program to compress a shell noscript?
Is there a program that allows to "compile" a shell noscript to a file that still can be run by the normal shell interpreter, but is as small as possible in size? With measures like
* All indentation and comments removed
* Variables and functions renamed to one and two letter words
* Frequently used pieces of code assigned to aliases / variables
All I can find with google are common data compressors, like .zip.

Whether you’re updating packages, cleaning up unused stuff, or automating routine tasks, robohelp does it with a simple set of commands.
I tryed to build it with simplicity and efficiency in mind, robohelp makes your everyday Linux tasks smoother (hopefully).

A Bash wrapper I wrote to manage multiple Docker Compose projects (looking for feedback)
I’ve been running into the same annoyance on servers and homelab machines: managing a growing number of unrelated Docker Compose projects spread across different directories.
Rather than relying on aliases or strict directory conventions, I ended up writing a small Bash wrapper that lets me refer to Compose projects by name and run `docker compose` commands from anywhere.
Example usage:
dcompose media
dlogs website
ddown backup
From a Bash perspective, the noscript:
* auto-discovers Compose projects in a set of common base directories
* keeps a simple registry file for manually added paths
* is pure Bash
* is meant to work well over SSH and on servers
* tries to keep error messages and output readable in a terminal
Repo is here if you want to look at the noscript:

Happy to hear feedback.

Thoughts from a system engineer that became a developer
Coding is a craft. At least, that's what it is for me.
I'm continuing my project of documenting my experience as I revisit Bash after years spent as a full-time developer. Can we apply the same mindset we use for complex software project to simple noscripts? Is there a benefit?
I wrote an article about how acquiring a testing mindset can help writing better code, even if at the end you write no test at all (you can read it here, if you like).
Feedback is appreciated.
