Risk Management Compliance Log Analysis Pipeline

Create a comprehensive Bash pipeline that scans financial transaction logs for potential compliance violations. The script must: 1) Parse JSON and CSV transaction logs, 2) Implement regex-based pattern matching for suspicious transaction characteristics, 3) Generate real-time alerts for transactions exceeding risk thresholds, 4) Output structured reports compatible with SEC and FINRA reporting standards. Include mechanisms for handling large log files (10GB+) with memory efficiency.
