Automation Example

#!/bin/bash
# Automated tcpdump 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..."

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

done < "$TARGETS_FILE"

# Generate summary report
tcpdump report summary \
    --input "$RESULTS_DIR/*.json" \
    --output "$RESULTS_DIR/summary.html"
