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..."

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