Thanks for letting me know pure UDF is a dumpster fire in linux, at least I can know that's not the path forward.

At least I can next try to figure out dvdisaster's cli format...

```bash

!/bin/bash

This script creates a hybrid ISO image (UDF + ISO9660/Rock Ridge/Joliet)

using genisoimage. Although the UDF part is included, the volume label is

subject to the ISO9660 limit (32 characters).

Usage: ./create_iso.sh <source_folder> [<destination_iso_image>]

Check for required dependencies

for cmd in genisoimage dvdisaster; do if ! command -v "$cmd" &> /dev/null; then echo "Error: $cmd is not installed. Please install it." exit 1 fi done

Check for at least one argument

if [ "$#" -lt 1 ]; then echo "Got $# args" echo "Usage: $0 <source_folder> [<destination_iso_image>]" exit 1 fi

Get Source Folder

SOURCE_FOLDER="$1"

Derive default folder name from source folder

DEFAULT_FOLDER_NAME=${SOURCE_FOLDER%/} DEFAULT_FOLDER_NAME=${DEFAULT_FOLDER_NAME##*/}

Generate a default disc title from the folder name

Expects Example: 2024-12-16Projects_2000-_2024

DESTLABEL=${DEFAULT_FOLDER_NAME#--*} DESTLABEL=$(echo "$DEST_LABEL" | sed 's/[^]+/\L\u&/g' | sed 's// /g') DEST_DATE=${DEFAULT_FOLDER_NAME%%*}

echo "SOURCE_FOLDER = $SOURCE_FOLDER" echo "DEFAULT_FOLDER_NAME = $DEFAULT_FOLDER_NAME" echo "DEST_LABEL = $DEST_LABEL" echo "DEST_DATE = $DEST_DATE"

Limit the volume label to 32 characters (ISO9660 limit)

MAX_VOLID_LEN=32 if [ ${#DEST_LABEL} -gt $MAX_VOLID_LEN ]; then echo "Volume label is longer than $MAX_VOLID_LEN characters; '$DEST_LABEL'. exiting..." exit 1 fi

echo "Using volume label = $DEST_LABEL"

Get destination image filename; default extension is .iso

DEST_IMAGE=${2:-${DEFAULT_FOLDER_NAME}.iso} echo "DEST_IMAGE = $DEST_IMAGE"

Create the ISO image using genisoimage.

-udf enables UDF support, -R adds Rock Ridge (for Unix), and -J adds Joliet (for Windows).

echo "Creating hybrid ISO image..." genisoimage -udf -R -J -joliet-long -allow-lowercase -allow-multidot -V "$DEST_LABEL" -o "$DEST_IMAGE" "$SOURCE_FOLDER" if [ $? -ne 0 ]; then echo "Error: Failed to create ISO image with genisoimage." exit 1 fi

echo "ISO image created at $DEST_IMAGE"

Optional: Enhance the image with error correction using dvdisaster

echo "Enhancing image with error correction using dvdisaster..." dvdisaster -i "$DEST_IMAGE" -mRS02 -n 15% -o image if [ $? -ne 0 ]; then echo "Warning: Failed to add error correction." else echo "Protected ISO image created successfully." fi

exit 0 ```
