Linux: script for creating aMule-optimized Links (Artist and Album in Filename)

[secretmango]

aMule does not seem to support directories, unlike Soulseek. So if you simply share your music library, the result will be hard to search (no aritst or album info) or include a bunch of cover.jpg etc. that you dont want.

You can use this script to recursively link all files from your library to a single folder, including the directory names in the filename.

the script uses fd-find, a faster find alternative using a more standard syntax.

Script

#!/bin/sh

SHARE="$HOME/REPLACEME"

mkdir -p "$SHARE"

# Find all matching files and process them with null-delimited output to allow whitespaces
fd -e mp3 -e ogg -e m4a -e opus -e flac -e wav -e oga -e mp4 -e mkv -e avi \
    --type f --print0 --strip-cwd-prefix | while IFS= read -r -d '' file; do
    # Replace '/' with ' -- ' to use as new filename
    transformed_name=$(printf '%s\n' "$file" | sed 's/\// -- /g')

    # Symlink to share directory with new filename
    ln -s "$(realpath -- "$file")" "$SHARE/$transformed_name" 2> /dev/null
done

Example

Library:

Music-Library/
├── Artist 1
│   ├── Album A
│   │   └── Song 1.ogg
│   └── Album B
│       └── Song 2.ogg
└── Artist 2
    ├── Album x
    │   └── Song 3.ogg
    └── Album y
        └── Song 4.ogg

Resulting links:

'Artist 1 -- Album A -- Song 1.ogg'
'Artist 1 -- Album B -- Song 2.ogg'
'Artist 2 -- Album x -- Song 3.ogg'
'Artist 2 -- Album y -- Song 4.ogg'

Future ideas

The script could be extended to use mediainfo or ffprobe or maybe an even simpler and faster tool to add channels, codec (for m4a, m4b, mka, mkv, ogg, oga etc.), bitrate and VBR/CBR. This would make it significantly slower but add way more useful info to help people decide.

And of course a script to reverse this and convert the output back into a folder structure, once this system should be used by more people.

I made a more complex script based on that idea, using ffmpeg to add some basic audio information to the links, improving searchability on aMule even more.
