Bash Scripting vs. Python
For those of you who also write scripts in Python or another language besides Bash, How do you decide when to write a script in Python vs. a script in Bash? I'm trying to be economical with my study time, because if I spend a lot of time learning some limited use functionality in one language, I could have used that time to learn a more general use functionality in another language. Here's an example: I've spent a fair amount of time learning awk, but I've never been great at using it, and sometimes I think that I should have just used Path and regex objects in Python, instead.

Is it OK if I use an appimage-browser like default browser?
Hi, I am using a browser from an appimage. Could I use it like browser by default from bash?
I did the commands before for change one browser by another... maybe I can use these steeps again and change to new browser-appimage like default...
PS: what is the meaning of "submission" flag here in this sub?
Thank you and Regards!

i made a tool zed
zed
what is zed?
zed is a tool where you can do these stuff listed:
1. overwrite, overwrite is basically you enter a whole new text and the program writes the text to the file
2. linewrite, linewrite is basically you select the line in the file, and you enter the text you want to change, and the program changes the file line with the chosen text!
3. read, reads any file you throw at it
4. delete, self explanatory
5. delline, delete a specific line in a specific file
I WANT THE SOURCE CODE NOW:
ok chill, heres the source code link don't worry you can do whatever to it **https://gitlab.com/giorgich11/zed/-/blob/main/source.sh?ref\_type=heads**
oh... i am to lazy i want the compiled version:
sure go to **https://gitlab.com/giorgich11/zed/-/raw/main/zed?ref\_type=heads**
i want to install this:
okay, when you get the binary or just the .sh just do:
chmod +x zed
if you have the binary you can do 'mv zed /usr/bin/zed' requires sudo! if you don't want to just do whatever to it

Probably unnecessarily scared of wget's spider function
Trying to find a way to have wget check (maybe in the background?) the size of a website before I attempt to archive it. So if I wanted to run ````wget -m -k https://example-web.site````, I want a script that'll guesstimate how much space it'll take. I found [this](https://stackoverflow.com/a/6986163), with [this](https://github.com/izkreny/website-size/blob/master/website-size.sh) as the main script; dunno why you'd install the script when you can just copy-paste it into an executable file, but maybe I'm missing something.
So I was about to do that, when I came across [this](https://unix.stackexchange.com/a/743176):
> ...````--spider```` option i think unexpectedly deletes all files on disk and so my download of many Gigabytes and thousands of files was being accidentally deleted by this feature. so i run the command in a temporary directory to stop this behavior from accidently deleting files.
And now I'm petrified. Please advise!

Is there a way to capture keystrokes even though you're not at a prompt?
I'm spending a lot of time on the terminal, (/dev/ttyX, framebuffer, no X/wayland).
I have made some key binds to control screen brightness, set the font size, volume up/down, limit CPU clock frequency, ...
Problem is, it only works if I'm at a Bash prompt and not if a program is open (mc, vim, chawan, ...)
If eg, I've got vim open, I need to either find a terminal that has a Bash prompt open or exit vim before I can change the screen brightness.
My problem would be fixed if there would be some kind of a way for bash to capture certain key sequences even though a program is running.
Is that possible at all?
thanks!

I’m thinking seriously about switching to Linux. My idea is to first learn Bash scripting, try making some simple scripts, and at the same time start learning more about Linux distros and how the system works.
I feel like learning Bash first could help me understand Linux better instead of just using it casually.

A simple Bash wrapper for marking AI-assisted Git commits
I wrote a tiny Bash helper called with_ai that wraps tools like codex or claude, preserves the human author, and appends a marker like [AI:Codex] to commits created by that tool.
It’s basically a low-friction way to make AI-assisted lines stand out later in git blame without obscuring the human who is accountable for them. It also puts tool info into a $AI_TOOL environment variable so it's available to other programs.
There's also a blog post with a bit more context here: Blaming the Agent.
I'd love any feedback on the Bash approach, including cleaner wrapping patterns or obvious portability issues I might be missing.

OC I made a minimal fuzzel-based wallpaper picker that works on any WM fuzz-wall
Hey everyone,
I wrote a small POSIX shell script called fuzz-wall that lets you pick wallpapers interactively using fuzzel's dmenu mode. I wanted something dead simple that worked regardless of which WM or wallpaper setter I was using, so I built it.
What it does
You run fuzz-wall, fuzzel opens with a list of your wallpapers, you pick one, it gets applied. ESC to exit. No config file, no GUI, no bloat.
Supported wallpaper setters
\- swaybg (Sway)
\- swww (Hyprland, with fade transitions)
\- hyprpaper (Hyprland)
\- feh (i3, bspwm, dwm)
\- nitrogen (openbox, bspwm)
\- xwallpaper (general purpose)
The script auto-detects which one you have installed. On Wayland it prefers Wayland-native setters, on X11 it falls back to X11 setters.
Configuration
There is only one option, the wallpaper directory. It defaults to \~/Pictures/wallpapers and can be overridden:
FUZZ_WALL_DIR=\~/Pictures/walls fuzz-wall
You can bind it to a key in your WM config:
\# Hyprland
bind = $mod, W, exec, fuzz-wall
\# Sway
bindsym $mod+w exec fuzz-wall
\# i3
bindsym $mod+w exec fuzz-wall
Install
It is on the AUR:
```paru -S fuzz-wall
yay -S fuzz-wall```
Or clone manually and copy to \~/.local/bin.
Source: https://github.com/youngcoder45/fuzz-wall
AUR: https://aur.archlinux.org/packages/fuzz-wall
This is an AUR package. Happy to hear feedback, bug reports, or suggestions for new wallpaper setters to support. If your WM or setter is not listed, open an issue and I will add it.

Run vim in command substitution?
I have a script that launches terminal on some temp file so I can edit it with vim bindings then on quit, prints the content and removes the temp file. I want to assign the output to a variable--is this possible? When I attempt this it vim doesn't run because it's inside the command substitution(?).
Do I need to workaround this by providing an option for the script to not delete the temp file and handle it manually after by the other script running it after getting its contents?
P.S. Unrelated, but I have a lua plugin for mpv which runs this shell script to launch a new terminal instance with vim running. If I close mpv, this new terminal instance with vim still persists. I expect this to close since it's a child(?) process and the contents of the script as well as running the script itself are all done in the foreground. I came across a stackoverflow about something to do with a grandparent process that might contribute to this behavior where the child process doesn't terminate (not sure if it's related) and was wondering if anyone has a guess how to deal with this.
