The more Windows PC’s you have, the bigger the chance that you have a Linux machine.

### script to set all artist tags to based on its folder name
#### how it works
```auto
VAST_AUDIO_LIBRARY/ ← Run script HERE (current directory)
│
├── folder_to_artist_tag.sh ← The script file (place here)
│
├── 8th day/ ← FOLDER = Artist name "8th day"
│ ├── We All Belong.mp3 ← Check: artist tag = "8th day"?
│ ├── All You Got/ ← Subfolder (script searches recursively)
│ │ ├── 01 - Mazal Tov.mp3 ← Check: artist tag = "8th day"?
│ │ ├── 02 - Bounce.mp3 ← If tag = "8th Day" → UPDATE to "8th day"
│ │ └── 03 - Harmony.mp3 ← If tag = "8th day" → SKIP (already correct)
│ └── Brooklyn/
│ ├── 01 - Brooklyn.mp3
│ └── 02 - Don't Say Goodbye.mp3
│
├── Avraham Fried/ ← FOLDER = Artist name "Avraham Fried"
│ ├── song1.mp3 ← Check: artist tag = "Avraham Fried"?
│ ├── song2.mp3 ← If wrong → UPDATE to "Avraham Fried"
│ └── Album Name/
│ └── track.mp3 ← Also checked (recursive search)
│
├── Mordechai Ben David/ ← FOLDER = Artist name "Mordechai Ben David"
│ ├── track1.mp3 ← All files here get artist = "Mordechai Ben David"
│ └── track2.mp3
│
└── Yaakov Shwekey/ ← Each top-level folder = one artist
└── songs/
└── song.mp3
HOW IT WORKS:
═════════════
1. START in VAST_AUDIO_LIBRARY/
│
├─→ Find all folders (8th day/, Avraham Fried/, etc.)
│
└─→ For EACH folder:
│
├─→ Folder name = Expected Artist Name
│
├─→ Find ALL audio files inside (recursively)
│ (searches subfolders too)
│
└─→ For EACH audio file:
│
├─→ Read current artist tag
│
├─→ Does it match folder name?
│ │
│ ├─→ YES: Skip (already correct)
│ │
│ └─→ NO: Update tag to match folder name
│
└─→ Move to next file
EXECUTION:
══════════
Terminal view:
┌─────────────────────────────────────────────────────────┐
│ ploiny@computer:/media/VAST_AUDIO_LIBRARY$ │
│ │
│ $ bash folder_to_artist_tag.sh │
│ │
│ [CHECK] Looking for tools... │
│ [OK] eyeD3 found! │
│ [INFO] Using tool: eyeD3 │
│ │
│ [FOLDER 1/294] Processing: '8th day' │
│ [FILE 1/104] Checking: 8th day/song.mp3 │
│ Current: '8th Day' → Updating to '8th day' │
│ [SUCCESS] Updated! │
│ │
│ [FILE 2/104] Checking: 8th day/song2.mp3 │
│ Current: '8th day' → Already correct, skipping │
│ │
│ [FOLDER 2/294] Processing: 'Avraham Fried' │
│ ... │
└─────────────────────────────────────────────────────────┘
IMPORTANT RULES:
════════════════
✓ One artist = One top-level folder
✓ Folder name becomes the artist tag for ALL files inside
✓ Subfolders are OK (albums, etc.) - script searches recursively
✓ Files already matching = skipped (no unnecessary rewrites)
✓ Script must have WRITE permission to the files
✓ Works on: MP3, M4A, FLAC, OGG, WAV
EXAMPLE CORRECTION:
═══════════════════
BEFORE running script:
Folder: "8th day"
File: "8th day/song.mp3" has tag: artist="8th Day"
↑
(capital D)
AFTER running script:
Folder: "8th day"
File: "8th day/song.mp3" has tag: artist="8th day"
↑
(lowercase d - matches folder!)
```
#### basically if you want to browse your organized artists in music players the same way you do in file managers (like me) this should be helpful
#### execute doing “bash path/to/sript.sh” not “./script”
## very important: proper placement of script is crucial!!

Qin Device Identifiers script
Automatically collects phone information (IMEI, Bluetooth address, WiFi address) and saves it to a text file. usefull for saving the correct info when flashing us bands and then using sn write tool to replace these identifiers
How to use:
1. Connect your phone to the computer and make sure ADB is connected
2. Run the script
3. Enter the person’s name when asked
4. Enter the WiFi MAC address when asked (find it in Settings \> About Phone)
5. Done! The information is saved to “imei numbers.txt”

Ah, good point. I was just thinking to save it in the folder.

[@moderators](https://jtechforums.org/groups/moderators) can we move the python scripts into a new topic similar to this 1 but for python scripts? I think its its own thing. Obviously also only for cli style scripts… (not just random gui apps that happened to have been written in python)

My personal wrapper for yt-dlp instead of remembering their complex options which I usually need to download.
Uses basic option for downloading with thumbnail and metadata. Allows basic arguments like output directory quiet mode video or audio etc. Just see usage at the top of the script.
```bash
#!/usr/bin/env bash
# Dependencies: yt-dlp, ffmpeg
usage() {
cat <&2; exit 1
fi
if [[! -d "$2"]]; then
echo "Error: output directory does not exist: $2" >&2; exit 1
fi
outdir="$2"; shift
elif [["$1" =~ ^--?h(elp)?$]]; then
usage; exit 0
else
args+=("$1")
fi
shift
done
set -- "${args[@]}"
declare -a cmd=(yt-dlp -x --audio-format mp3 --embed-metadata --embed-thumbnail --no-playlist)
rv='^--?v(id(eo)?)?$' ra='^--?a(ud(io)?)?$'
if [[$# -eq 0]]; then
read -rp "Format - (a)udio or (v)ideo: " fmt
[["${fmt/quit/q}" == "q"]] && exit 0
read -rp "Title, URL, or q to quit: " query
[["${query/quit/q}" == "q"]] && exit 0
set -- "$fmt" "$query"
fi
if [["$1" =~ $rv || "${@: -1}" =~ $rv]]; then
cmd=(yt-dlp -S "res:720" --merge-output-format mp4 --embed-metadata --embed-thumbnail --no-playlist)
[["$1" =~ $rv]] && shift || set -- "${@:1:$#-1}"
fi
if [["$1" =~ $ra || "${@: -1}" =~ $ra]]; then
[["$1" =~ $ra]] && shift || set -- "${@:1:$#-1}"
fi
[[$quiet -eq 1]] && cmd+=(--quiet --no-warnings)
[[-n "$outdir"]] && cmd+=(-P "$outdir")
if [[-z "$2" && "${1:0:8}" == "https://"]]; then
[[$quiet -eq 1]] && echo "Downloading..."
"${cmd[@]}" "$1"
exit 0
fi
if [["${1:0:8}" != "https://"]]; then
declare -a res
[[$quiet -eq 1]] && echo "Searching..."
mapfile -t res < <(yt-dlp "ytsearch7:$*" -O "%(id)s|%(title)s - %(uploader)s (%(duration_string)s)")
for ((i=0; i<${#res[@]}; i++)); do echo "$((i+1)). ${res[i]#*|}"; done
read -rp "Please pick a number (1-${#res[@]}) or q: " ans
[["${ans/quit/q}" == "q"]] && exit 0
[[$quiet -eq 1]] && echo "Downloading..."
"${cmd[@]}" "https://youtu.be/${res[$((ans-1))]%|*}"

ever copied a prompt and the silly `$` tripped everything up?
* * *
no \_prompt\_prompt.sh
if first character is a `$` it ditches it
```auto
#!/usr/bin/env sh
# no_dollar.sh — Strip a leading '$' from commands before execution
# Works with: zsh, bash, and most POSIX-compatible shells
#
# INSTALL (pick your shell):
# zsh: echo 'source ~/no_dollar.sh' >> ~/.zshrc && source ~/.zshrc
# bash: echo 'source ~/no_dollar.sh' >> ~/.bashrc && source ~/.bashrc
#
# HOW IT WORKS:
# Hooks into the shell's pre-execution phase. If the first non-space
# character of your command is '$', it's silently stripped and the
# rest runs normally.
#
# Example:
# $ ls -la → runs: ls -la
# $git status → runs: git status
# $ echo "hello" → runs: echo "hello"
# ── zsh ──────────────────────────────────────────────────────────────────────
if [-n "$ZSH_VERSION"]; then
# zsh exposes the typed command via $BUFFER in preexec hooks.
# We use a preexec function to rewrite the command before execution.
_no_dollar_preexec() {
: # no-op — rewriting happens at read time via zle widget below
}
# Override the accept-line widget so the line is rewritten before execution
_no_dollar_accept_line() {
local stripped="${BUFFER#"${BUFFER%%[!]*}"}" # lstrip spaces
if [["$stripped" == \$*]]; then
BUFFER="${stripped:1}" # drop the '$'
fi
zle .accept-line # call the real accept-line
}
zle -N accept-line _no_dollar_accept_line
# ── bash ─────────────────────────────────────────────────────────────────────
elif [-n "$BASH_VERSION"]; then
# bash doesn't have a pre-exec ZLE equivalent, so we wrap the DEBUG trap.
# The trick: rewrite $BASH_COMMAND isn't possible, but we CAN use a
# function that bash calls via the prompt command to sanitise readline input.
#
# Approach: override the readline binding for Return so we can preprocess.
# Since bash readline is harder to hook cleanly, we use a PROMPT_COMMAND
# trick with `history` to detect and warn, combined with a bash function
# alias fallback that covers the most common case.
# Primary method: bind Return to a bash function via readline macro
# This covers interactive input in bash 4.0+
_no_dollar_run() {
local cmd
# Read the current readline buffer via builtin
cmd="$(history 1 | sed 's/^[[:space:]]*[0-9]*[[:space:]]*//')"
local stripped="${cmd#"${cmd%%[!]*}"}"
if [["$stripped" == \$*]]; then
local clean="${stripped:1}"
# Replace the history entry and re-run
history -s "$clean"
eval "$clean"
fi
}
# Fallback: command_not_found_handle catches `$ git status` style mistakes
# where the shell tries to run a command literally named '$'
command_not_found_handle() {
# Called when the shell can't find a command named e.g. '$'
# Reconstruct the rest of the args as the real command
if [["$1" == '$']] && [[$# -gt 1]]; then
shift
"$@"
return $?
fi
# Default not-found message for everything else
echo "bash: $1: command not found" >&2
return 127
}
# Also handle: user types `$ ls` → shell tries to exec a binary named `$`
# The command_not_found_handle above catches this cleanly in bash 4+.
