Fish like ghost completion for bash

Hi Guys,

I tried to implement fish like autocompletion suggestion for bash but I overrides the current prompt. I am trying to make this better. If you have any suggestions please let me know.

How to assign default value to variable and convert to uppercase in 1 line?

I typed this in the browser search box and Google AI said this is supposed to work

VAR=${VAR^^:-DEFAULT_VALUE}

I tried it inside a noscript file (.sh) and in the console and it does not work.

Any ideas on how it can be done? thanks

PS: I'm using bash 5.x

Bash tool to view Linux group info

I was reading the book "Practical Linux System Administration" and it mentioned the "groupmems" command, and I noticed it's missing on Debian 13. So I wrote a small Bash noscript to view regular group members and improved it over a few days.
It only shows regular group info. It can list groups with no members, it separates users for whom a group is primary from those for whom it’s supplementary, and a few other small features.
I'll add some account sprawl checks to it I guess.
If you think of anything practical that fits the scope, I can add it.

I challenge you to answer this question :)

Which awk command will correctly parse the /proc/1234/smaps file to sum the Pss (Proportional Set Size) memory for all private, clean memory mappings belonging to the process?

A. awk '/^Pss:/ {pss=$2} /Private_Clean/ {sum += pss} END {print sum}' /proc/1234/smaps

B. awk '/^Pss:/ {sum += $2} END {print sum}' /proc/1234/smaps

C. awk '/Private_Clean/ {getline; if ($1=="Pss:") sum+=$2} END {print sum}' /proc/1234/smaps

D. awk 'BEGIN {RS="\\n\\n"} /Private_Clean/ {for(i=1;i<=NF;i++) if($i=="Pss:") {sum+=$(i+1); break}} END {print sum}' /proc/1234/smaps

Script creating tmux session

Hi, I am finding it difficult to get the desired outcome from the following line in my server start noscript.

tmux new-session -d -s ${TMUX_SESSION} ${SERVER_COMMAND} | tee -a ${LOG}

This starts the server properly in Tmux and I'm able to connect to the session and send commands in other noscripts. My problem is specifically with tee not appending the output of the server command to the log. It seems to be appending the output of the Tmux new-session command (which is nothing).

I've tried putting the server command and tee in ` but I get command too long error.

I've also tried issuing the start command the same way I do the server action commands with tmux send-keys. My server starts and logging is correct, but the tmux session is not persistent so I can't review and I believe my action commands won't run.

Any ideas for nesting this properly?

bash: warning: command substitution: ignored null byte in input

i don't even know if it's right to post it here, but I'm having that problem whenever I try to use bash-completion with yay -S ... I don't know what to do. I thought it was Starship so I deleted it, but it kept happening. It's not something that is going to k1ll me, but I would love if anyone could help me.

Script to unrar file I right click on?

For some reason Linux Mint's archive manager crashes every time you use the right click "extract here" option for multi-part rar archives and you need to right click the file explorer, open in terminal, and then type "unrar x \*part1.rar" to extract the files.

As there is no way I can find just set unrar x as some kind of setting in archive manager my idea was to write a .sh noscript, place it in "/Applications", and add it to the list of "Open With" programs so now I have a right click option to extract rar files easier. But I can't get the code to work.

#!/bin/bash
if "*part1.rar" do unrar x
Pause -p "Check for errors then press any key to continue"
exit

h - A Bash Help Tool for Aliases, Functions, Keywords, and Commands



---

Title:
h – is a full fledged command resolution engine that unifies help into one shortcut - h

Body:
Hi Everyone!

I’ve been working on a tool called h that helps you understand exactly what a Bash command is doing, whether it’s an alias, function, builtin, keyword, or external command.

---
Repo:
https://github.com/JB63134/bashh

---

## **Features**

* Analyze **builtins, aliases, keywords, functions, and external commands**
* Shows **where a command is defined** (files, line numbers, or shell)
* Displays **alias expansions** and function contents
* Provides **help output** or points to `man` / `info` pages
* Syntax-highlighted preview for functions and noscripts (`batcat` preferred, fallback to Perl)
* Integrates with **fzf** for interactive command search
* Automatic detection of commonly used **admin paths**

---

## **Usage**

```bash
h [command] # Analyze the given command
h # Analyze your most‑recent command
h -f # Launch interactive search using fzf
h -h | --help # Show usage instructions
h -v | --version # Show version info
```

---

## **Examples**
