Error oh my bash theme development

Good evening everyone, I'm making another theme for Oh My Bash that has the same base as my old theme, but it's not overwriting the base properly, these are the codes



New theme

if [ -z "${NEKONIGHT_BASE_LOADED}" ]; then
  source ~/.oh-my-bash/themes/nekonight/nekonight-base.sh
  export NEKONIGHT_BASE_LOADED=true

Sed replacement with a variable needs single and double quotes

Hi all, this may be a stupid question, so sorry in advance. I have just started to get into the world of bash noscripting, and I decided to create an install noscript for my NixOS build. Within that, I want to create a new host, so I have decided to use sed to add a block of Nix code from a text file in place of a comment that I have there by default. The problem arises then that I need to evaluate bash noscript within it using double quotes "" as well as using the s option at the start, which from what I can see only works with single quotes ''.
From what I could find when googling this, I need to exit the single quotes with double quotes when writing the expression, then go back to singles to finish it.
https://askubuntu.com/questions/1390037/using-sed-with-a-variable-inside-double-quote

So this is what i have so far sudo sed -i 's|#Install new host hook|'"$(< /etc/nixos/noscripts/helperFiles/newHostFlakeBlock.txt)"'|' /etc/nixos/flake.nix

Creating a simple latex launcher

Hello!

I'm not sure I'm posting in the good subreddit, don't hesitate to redirect me!

I've a little problem I'm not able to solve, because I don't understand well enough the problem to know where to search.

I would like to create a noscript that manages a .tex file such as :
- it opens a terminal and launches latex -pdf -pvc $FILE, $FILE being the argument file
- it opens the file with kwrite

Ideally, I declare this noscript as an application that I can set as the default application for .tex files. This way, when I double click on the file every of these actions execute themselves.

I first tried to create a latex.sh noscript (yes it's executable) :

#!/bin/bash
latexmk -pdf -pvc $1 &
kwrite $1 &

Then I added a .desktop file in ~/.local/share/applications and tried to open a .tex file with this application. Without surprise it does not work, but I don't really know what exactly is the process I want to see in the system so it's difficult to improve the noscript...

Thanks in advance for your help!

Importance of checking IFS

I just wanted to spread a word about importance of explicitly defining and assigning values to IFS.

After years of noscripting in bash in Ubuntu i never thought of non standard IFS values in other linux based operating systems.

Few minutes ago figured out why some of my noscripts weren’t working properly in openwrt. IFS in openwrt contains only /n newline character vs tab space and newline.

Can be checked by looking into environment via set (printenv is not installed by default) or simply by echoing IFS and piping into cat: echo “$IFS” | cat -A

Hope this will save someone down the road from wasting hours on debugging.

My noscripts weren’t working simply copied to openwrt as they were working on Ubuntu and didnt show any issues at first glance. I want to pinpoint here that i didnt write in openwrt environment or else i would have checked IFS. From now on i will make a habit to assign it right after the shebang.

Thanks.

HELP!

I'm trying to make a simple OS that uses BASH and coreutils as a base.
I searched and asked to chatgpt how to compile it to a unknown os and basically everything went wrong.

btw, i'm on windows 11 with nasm,gcc, mingw, msys2 and Arch WSL.
Can someone help me?

Chatgpt in bash

Hi, first post here so please go easy..... !

I love modifying bash, and have recently thought about having Chatgpt work directly from bash by just typing a simple command whenever needed/wanted. As a result i have created the following, it seems to work fine and have added a menu to it for added functionality.

Feedback would be most welcome please - https://github.com/Fenlanddavid/AI-command/blob/main/gpt.sh

Simple noscript to integrate chat-gpt into bash

Will try this post again now...

I love messing around and modifying bash, my latest project has been to integrate chat-gpt into the command line. wanted to just type a normal command and have it reply whenever i needed/wanted it too. It became a little more complicated as i went on and had to add various functions such as save session memory for it to be effective-also added a simple menu. Works ok on my system but just after a little feedback please **you will need your own openai API key**

Shunpo: A Bash Tool for Quick Directory Navigation

Hi fellow redditors. I recently wrote a minimalistic navigation tool for bash. A few of my colleagues liked it, so I thought I'd make the repository public and share it. Here's a video demo-ing it . I hope it helps speed up your navigation!

YAML manipulating with basic tools, without yq

The problem. I have a YAML file with this:

network:
version: 2
renderer: networkd
ethernets:
wifis:
wlx44334c47dec3:
dhcp4: true
dhcp6: true

As you can see, there is an empty section ethernets, but we could also have wifis section empty. This is invalid structure and I need to remove those empty sections:

This result:

network:
version: 2
renderer: networkd
wifis:
wlx44334c47dec3:
dhcp4: true
dhcp6: true

can be achieved easily with:

yq -y 'del(.network.ethernets | select(length == 0)) | del(.network.wifis | select(length == 0))'

But I want to achieve the same with sed / awk / regex. Any idea how?

convert nested css to standard syntax css

Hi im new in this sub and i don't have much experience with bash in general, i was trying to create a noscript that allows me to convert nested css that has multi-selector in to standard css, currently i got my noscript working for nested css, but it seem i can't find a way to eleaborate multi selector (es. #foo, .bar).
Also tryed to ask gpt but it just added some comments and made me feel more miserable.
Can someone give me a hand?

Get stderr and stdout separated?

How would I populate e with the stderr stream?

r="0"; e=""; m="$(eval "$logic")" || r="1" && returnCode="1"

I need to "return" it with the function, hence I cannot use a function substitution forward of 2> >()

I just want to avoid writing to a temp file for this.

Why is "set -e" not the default or not left in noscripts after creation?

"set -e" as most of you know will exit a noscript on error. It (and other set commands) is often used in a noscript during development when errors are expected and you want immediate halt.

But why is this behavior not the default anyway? Surely in vast majority of cases when a noscript is in production and there is an error, you would want the noscript to halt rather than attempt to execute the rest of it (much of which will have dependency and less likely to just be an independent process)?

find $backup_dir -depth -type d -mtime +$backup_retention_time -exec rm -r {} \;

'''

My main goal is to implement a rolling backup/retention strategy, i.e. I want to keep

* 24 hourly backups
* 7 daily backups
* 12 monthly backups

Any help is greatly appreciated!

EDIT: changed the timestamp from %Y-%m-%dT%H:%M to %Y-%m-%dT%H-%M for better compatibility.

How to configure terminal to show the entire previous command, without truncating it with an ellipsis?

Using iterm2 on MacOS with ZSH and powerlevel10k and Oh-My-Zsh. Nothing unusual.

When I paste a long `curl` command (with a request body that has a few dozen lines or more) into the terminal and execute it, I want to see the entire command when I press the Up arrow key to reload the last command from my history.

But what actually happens is only the last 30 or so lines of the command are shown when I press the Up arrow key, truncating all the lines above with an ellipsis (...).

I want to configure my terminal to actually display the *whole* entire command when I press Up.

I assume this is a config issue somewhere either in my `\~/.zshrc` file or the `\~/.p10k.zsh` file, but have no clue if that's correct.
