Automated xxd workflow

Configuration

TARGETS_FILE=“targets.txt” RESULTS_DIR=“results/$(date +%Y-%m-%d)” CONFIG_FILE=“automation.yaml”

Create results directory

mkdir -p “$RESULTS_DIR”

Process each target

while IFS= read -r target; do echo “Processing $target…”

xxd \
    --config "$CONFIG_FILE" \
    --output json \
    --output-file "$RESULTS_DIR/$\\\\{target\\\\}.json" \
    run "$target"

done < “$TARGETS_FILE”

Generate summary report

xxd report summary
—input “$RESULTS_DIR/*.json”
—output “$RESULTS_DIR/summary.html”
