Here is the same project brief rewritten in a professional format without emojis: --- Project Brief: Linux (RHEL) Shell Scripting – Execution and Automation Project Summary We require an experienced Linux professional with strong shell scripting expertise (Bash or Korn Shell) to develop, execute, maintain, and optimize automation scripts in a production environment. The scripts support high-volume batch processing workflows, including file ingestion, validation, execution monitoring, and cleanup. This is a live production system requiring reliability, performance, and structured implementation. Scope of Work 1. Shell Scripting Development * Create, modify, and optimize Bash/KSH scripts * Automate batch processing workflows * Implement structured logging * Implement proper exit codes * Add robust error handling and retry mechanisms * Ensure scripts follow enterprise coding standards 2. Script Execution and Monitoring * Configure and manage execution via cron or enterprise scheduler * Monitor daily batch jobs * Troubleshoot failures and analyze logs * Identify root causes and implement permanent fixes * Improve execution reliability 3. File and System Management * Automate file movement between directories * Manage file permissions and ownership * Implement disk space monitoring scripts * Create safe file cleanup processes * Ensure proper directory structure and environment management 4. Performance Optimization * Reduce script execution time * Optimize CPU, memory, and disk usage * Improve scalability for large batch loads * Provide recommendations for system improvements Technical Environment * Operating System: Red Hat Enterprise Linux (RHEL 8/9) * Scripting: Bash or Korn Shell * Scheduler: Cron or enterprise job scheduler * File Types: Large batch files (PDF, AFP, logs) * Logging: System and application logs * Platform Exposure (Preferred): IBM Content Manager OnDemand (CMOD) Required Skills Mandatory * Strong experience with RHEL administration * Advanced shell scripting expertise * Production support and troubleshooting experience * Log analysis and debugging capability * Experience with cron scheduling Preferred * IBM CMOD ingestion knowledge * Banking or financial services experience * Basic SQL knowledge Deliverables * Well-structured and optimized shell scripts * Reliable and automated batch workflows * Improved logging and error handling framework * Performance improvement recommendations * Clear documentation of scripts and processes Success Criteria * Scripts execute without manual intervention * Batch failure rate significantly reduced * Improved execution performance * Clean and meaningful log output * Proper documentation delivered Engagement Details * Freelance or contract-based * Remote work * Initial duration: 4 to 8 weeks (extendable based on performance) * Availability overlap with EST time zone preferred Proposal Requirements Please include the following in your proposal: * Years of Linux experience * Sample shell scripting work (if available) * Experience in production environments * Hourly rate and availability If needed, I can also create a shorter version suitable for quick job posting platforms or a more technical version for senior-level candidates.
