☄️ Structured Personality AI Experiment (llama.cpp)

previous tests with “Alex” and R12D12, here’s a collection of entities with predefined behavior. These are not general-purpose chatbots, but functional narrative profiles — each with its own internal framework.

Robots:

HAL\_10
Da1ta1
Vender
CC-33PPOO

Each one:

🤖 responds from within its role, not from the user’s intent
🫡 maintains tone, structure, and narrative constraints
🎭 doesn’t improvise, it interprets
🔄 doesn’t hallucinate, it follows internal logic

Designed to run fully offline — no RAG, no embeddings, no external dependencies.
Just prompt engineering, modular structure (prompt.txt, config, README, and per-profile examples).
Repository:
(http://github.com/BiblioGalactic/Robotsdelamanecer)
Can serve as a base for operational simulation, narrative training, or controlled interaction with role-based AIs under local execution.

Newbie - Need help understanding an error in my noscript

Hey guys, I have a basic bash noscript I made for the purpose of checking for any disconnected file shares (missing mount points) on my proxmox VE host and automatically attempting to re-map the missing shares. This is so that if my NAS turns on after my proxmox VE host for any reason, I won't have to log into the host manually and run "mount -a" myself.

This is literally my first bash noscript beyond the usual "Hello World!" (and first noscript of any kind outside of basic AutoHotkey noscripts and some light PowerShell). At this stage, my noscript is working and serving its intended purpose along with an appropriate cron job schedule to run this noscript every 5 minutes, however I am noting an error "./Auto-Mount.sh: line 59: : command not found" every time the noscript runs and finds that a file share is missing and needs to be reconnected. If the noscript exits after finding that all file shares are already connected, this error is not logged. Regardless of this error, the noscript functions as expected.

I have identified which line (line 59: if "$any_still_false"; then) is throwing the error but I can't for the life of me understand why? Any help you guys could offer would be awesome... Feel free to constructively critique my code or documentation as well since it's my first go!

Side note: I'm hoping entering the code into this post with a code block is sufficient to make this as readable as possible. If there's a better way of formatting this in a reddit post, please tell me so I can edit the post.

Personality system

🧠 I'm working on an AI personality system using llama.cpp completely locally. All orchestration is done in Bash with modularity by profiles (prompt.txt, config, launcher.sh, etc.).



Has anyone else worked with Bash to structure prompts or handle contextual memory? I'm using Levenshtein distance + token control, and I would love technical feedback on the architecture of the noscripts.

Read command resulting in a lack of logs.

In my bash noscript, I have a function that logs some stuff and then requests a user input based on the content logged before it. The issue is that those logs don't get logged until I do the user input first, which is obviously not intended. Am I doing something wrong?

I'm using:
read -p "Input: " choice

Also, if it helps, I'm using Git Bash for Windows.

Thanks for the help in advance!

How to make bash noscript to archive each folder to separate rar/zip and retain the name?

The folder structure is

\- Main Folder

\-- Subfolder

\---Subsubfolder

\---Subsubfolder

\-- Subfolder

\---Subsubfolder

\---Subsubfolder

I want to archieve each subsubfolder that have different name and retain the rar name same as the original folder name. I tried by using this video noscript, this comment noscript, this noscript, and using chat gpt but still no clue.

Process Priority Manager

# nicemgr

## The Story

I am ashamed to admit, despite years doing sysadmin work/software development, it wasn't until today that I learned about nice values for running processes. For those of you that also are unaware, a nice value tells your OS which programs to prioritize, and by what weights, when resources are constrained.

My relevant example, a long running ffmpeg process, making it impossible to use my computer for days, but me desperately desiring to play BG3 in the evening after work. Solution: nice values. Nice indicates how willing a process is to share CPU cycles with other programs. They range from -20 through 20. Negative nice values are greedy and unwilling to share. Positive values are happy to get whatever CPU cycles are available. The higher the nice value, the happier they are to let other processes use all of your CPU resources.

The solution worked great, but I was finding it a bit of a chore going through all the steps to find the PID, check the current nice value, or adjust them as the syntax isn't the most memorable. I'm attaching a wrapper below for those interested. This can be used across macOS and most linux distros. Hope you find this helpful!!

## TLDR;
- **What “nice” is:** process priority from –20 (greedy) to +20 (polite)
- **Why it matters:** lets CPU-hog jobs yield to interactive apps
- **My use-case:** reniced ffmpeg so I could finally play Baldur’s Gate 3
- Wrapper noscript below to simplify use of this nifty tool

using parenthesis for execution

Is there any advantage or disadvantage to using parenthesis for the following execution of the "find" command:


sudo find / \( -mtime +30 -iname '*.zip' \) -exec cp {} /home/donnie \;

as opposed to using the same command without the parenthesis like so:

sudo find / -mtime +30 -iname '*.zip' -exec cp {} /home/donnie \;

Both seem to produce the same result, so don't fully understand the parenthesis in the first "find". I am trying to make sure that I understand when and when not to use the parenthesis considering that it can affect the flow of evaluation. Just thought in this example it would not have mattered.

thanks for the help

timep: a next-gen time-profiler and flamegraph-generator for bash code

`timep` is a **time p**rofiler for bash code that will give you a per-command execution time breakdown of any bash noscript or function.

Unlike other profilers, `timep` records both wall-clock time and cpu time (via a loadable builtin that is base64 encoded in the noscript and automatically sets itself up when you source timep.bash). Also unlike other profilers, `timep also recovers and hierarchially records metadata on subshell and function nesting, allowing it to recreate the full call-stack tree for that bash code.

***

**BASH-NATIVE FLAMEGRAPHS**

If you call `timep` with the `--flame` flag, it will automatically generate a BASH-NATIVE flamegraph .noscript image (where each top-level block represents the wall-clock time spent on a particular command, and all the lower level blocks represent the combined time spent in the parent subshells/functions...this is not a perf flamegraph showing syscalls). Furthermore, Ive added a new colorscheme to the flamegraph generation noscript that will:

1. color things that take up more time with hotter colors (normal flamegraph coloring is "random but consistent for a given function name")
2. desaturate commands with low cpu time/ wall time ratio (e.g., wait, sleep, blocking reads, etc)
3. empirically remap the colors using a runtime-weighted CDF so that the colorscale is evenly used in the flamegraph and so extremes dont dominate the coloring
4. multiple flamegraphs are stacked vertically in the same noscript image.

[HERE](https://raw.githubusercontent.com/jkool702/timep/main/TESTS/FORKRUN/flamegraphs/flamegraph.ALL.noscript) is an example of what they look like (details near the bottom of this post).

***

**USAGE**

To use `timep`, download and source the `timep.bash` file from the github repo, then just add `timep` before whatever you want to profile. `timep` handles everything else, including (when needed) redirecting stdin to whatever is being profiled. ZERO changes need to be made to the code you want to profile. Example usage:

. timep.bash
timep someFunc <input_file
timep --flame /path/to/someScript.bash
timep -c 'command1' 'command2'

`timep` will create 2 time profiles for you - one that has every single command and full metadata, and one that combines commands repeated in loops and only shows run count + total runtime for each command. By default the 2nd one is shown, but this is configurable via thge '-o' flag and both profiles are always saved to disk.

For more info refer to the README on github and the comments at the top of timep.bash.

**DEPENDENCIES**: the major dependencies are bash 5+ and a mounted procfs. Various common commandline tools (sed, grep, cat, tail, ...) are required as well. This basically means you have to be running linux for timep to work.

* bash 5+ is required because timep fundamentally works by recording `$EPOCHREALTIME` timestamps. In theory you could probably replace each `${EPOCHREALTIME}` with `$(date +"%s.%6N")` to get it to run at bash 4, but it would be considerably less accurate and less efficient.
* mounted procfs it required to read several things (PPID, PGID, TPID, CTTY, PCOMM) from `/proc/<pid>/stat`. `timep` needs these to correctly re-create the call-stack tree. It *might* be possible to get these things from external tools, which would (at the cost of efficiency) allow `timep` to be used outsude of linux. But this would be a considerable undertaking.

***

**EXAMPLES**

Heres an example of the type of output timep generates.

```
testfunc() { f() { echo "f: $*"; }
g() ( echo "g: $*"; )
h() { echo "h: $*"; ff "$@"; gg "$@"; }
echo 0
{ echo 1; }
( echo 2 )
echo 3 &
{ echo 4; } &
echo 5 | cat | tee
for (( kk=6; kk<10; kk++ )); do
echo $kk
h $kk
for jj in {1..3}; do
f $kk $jj
g $kk $jj
done
done
}
timep testfunc

gives

TOTAL RUN TIME: 0.025939s
TOTAL CPU TIME: 0.024928s

A example on a complex real code: some of you here may have heard of another one of my projects: [forkrun](https://github.com/jkool702/forkrun). It is a tool that runs code for you in parallel using bash coprocs. i used timep on forkrun computing 13 different checksums of a bunch (~620k) of small files (~14gb total) on a ramdisk...twice (in total ~16.1 million checksums on 384 gb worth of (repeated) data). I figure this is a good test, since not only is forkrun a technically challenging code to profile, but it is a highly parallel workload. On my 14c/28t i9-7940x this run (with 28 active workers), on average, used just under 23 cores worth of CPU time. the exact code to setup this test is below:

mount | grep -F '/mnt/ramdisk' | grep -q 'tmpfs' || sudo mount -t tmpfs tmpfs /mnt/ramdisk
mkdir -p /mnt/ramdisk/usr
rsync -a --max-size=$((1<<22)) /usr/* /mnt/ramdisk/usr
find /mnt/ramdisk/usr -type f >/mnt/ramdisk/flist
find /mnt/ramdisk/usr -type f -print0 >/mnt/ramdisk/flist0
ff() {
sha1sum "${@}"
sha256sum "${@}"
sha512sum "${@}"
sha224sum "${@}"
sha384sum "${@}"
md5sum "${@}"
sum -s "${@}"
sum -r "${@}"
cksum "${@}"
b2sum "${@}"
cksum -a sm3 "${@}"
xxhsum "${@}"
xxhsum -H3 "${@}"
}

export -f ff
timep --flame -c 'forkrun ff </mnt/ramdisk/flist >/dev/null' 'forkrun -z ff </mnt/ramdisk/flist0 >/dev/null;'
