🎯 AUTOMATION EXAMPLE:

Bash script to process the result:
```bash
#!/bin/bash
# Run the eBay scraper and get the result file
result=$(python3 login.py)
file_path=$(echo $result | jq -r '.file')

echo "Data saved to: $file_path"
echo "File size: $(du -h "$file_path" | cut -f1)"
echo "Items count: $(jq '.total_items' "$file_path")"

# Process the data further
python3 process_data.py "$file_path"
```

Python script to process the result:
```python
import subprocess
import json

# Run the scraper
result = subprocess.run(['python3', 'login.py'],
                       capture_output=True, text=True)

if result.returncode == 0:
    output = json.loads(result.stdout.strip())
    file_path = output['file']

    print(f"Data saved to: {file_path}")

    # Load and process the data
    with open(file_path, 'r') as f:
        data = json.load(f)

    print(f"Total items: {data['total_items']}")
    print(f"Search keywords: {data['search_parameters']['keywords']}")

    # Process items...
    for item in data['items']:
        print(f"- {item['title']}: {item['price']}")
```

🚀 KEY BENEFITS:

✅ Automation Friendly:
  • Clean JSON output for easy parsing
  • Absolute file path for reliable access
  • Silent execution prevents log noise

✅ Error Handling:
  • Critical errors still visible
  • Non-zero exit codes on failure
  • JSON only output on success

✅ Flexible Usage:
  • Normal mode: JSON output for scripts
  • Debug mode: Human-readable for development
  • Both modes create the same data files
