@mayankinnovative

Hi, As per my understanding: You require a seasoned RHEL professional to design, optimize, and maintain production-grade Bash/KSH scripts supporting high-volume batch workflows. The environment is live, so reliability, structured logging, proper exit handling, scheduler integration, and performance optimization are critical. The goal is stable automation, reduced batch failures, improved monitoring, and enterprise-standard scripting across RHEL 8/9 systems. Implementation approach: I will begin with an audit of existing scripts, cron/scheduler setup, and log structure to identify instability points. Then I’ll refactor or build modular shell frameworks with standardized logging, exit codes, retry logic, and parameter validation. I’ll implement robust error trapping, disk/permission checks, and safe file lifecycle management. For monitoring, I’ll enhance cron/scheduler integration with alert-ready logs. Performance tuning will focus on I/O efficiency, parallelization where safe, and resource optimization. Final delivery includes hardened scripts, documentation, and measurable reliability improvements. A few quick questions: Is there an existing scripting standard to align with? Are batch failures mostly I/O, permission, or application-level? Is CMOD integration already functional or part of enhancement scope?
