Create results directory¶

mkdir -p "$RESULTS_DIR"

Process each target¶

while IFS= read -r target; do echo "Processing $target..."

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

done < "$TARGETS_FILE"

Generate summary report¶

signal report summary \ --input "$RESULTS_DIR/*.json" \ --output "$RESULTS_DIR/summary.html" ```_
