Ensure inodes of files in a folder are in the same order as the filename order. Because my Aygo x-Play's USB reader sorts by inode. Wtf.

reset-inode-order.sh

#!/usr/bin/env bash

deepset() {
    find . -type d -exec bash "$0" {} \;
}


hasmp3() {
    ls *.mp3 >/dev/null 2>&1
}

check_exit() {
    if [[ -f "$MAINDIR/exit_now" ]] || [[ -f "$MAINDIR/exit_${1:-}" ]]; then
        echo "<< Abort // $(ls "$MAINDIR"/exit_*) >>"
        exit 99
    fi
}

set_order() {
    check_exit album
    (
    cd "$1"
    if hasmp3; then
        echo "---- $1 ----"
        todelete=()
        for audiofile in *.mp3; do
            check_exit track
            echo -n "$audiofile ;; "
            todelete+=("$audiofile")
            cp "$audiofile" "${audiofile}-new" || exit 1 # Support non-hardlinking filesystems. Change to `ln` for better performance
            check_exit track
        done

        echo " -- Cleaning up ..."

        for target in "${todelete[@]}"; do
            rm "$target"
            mv "${target}-new" "$target"
        done
    fi
    )
}

MAINDIR="${MAINDIR:-$PWD}"
export MAINDIR

if [[ -z "$*" ]] || [[ "$*" =~ --help ]]; then
    echo "$0 [--] FOLDER ..."
    echo "Use the '--' token to indicate a deep recursion"
    echo "During the run you can \`touch ./exit_now\` in the same working directory to interrupt the execution safely as soon as possible."
    echo "Other exits are: ./exit_track (after current track), ./exit_album (after current album/leaf folder), ./exit_folder (after current named/upper folder)"
    echo ""

elif [[ "$1" = -- ]]; then
    shift
    for folder in "$@"; do
        check_exit folder
        (
        cd "$folder"
        deepset
        )
    done

else # Does not recurse ; note that `deepset` depends on this behaviour
    for folder in "$@"; do
        check_exit folder
        set_order "$1"
    done
fi

The snippet also allows safely interrupting the operations - interrupt after conversion of track, album or named folder with one of

touch ./exit_track
touch ./exit_album
touch ./exit_folder
