user management

Turn brittle spreadsheet-to-shell onboarding/offboarding into a safe, auditable workflow by pairing Bash with a dash of AI: normalize messy HR exports (via OpenAI-compatible APIs or Ollama) to a strict schema, generate an idempotent plan to create/update/remove users and groups, dry-run, log, and schedule with cron; includes distro installs, a full script, guardrails, and a real-world example.

A practical guide to blending AI and Bash for user management: turn natural-language requests into safe, auditable JSON plans and deterministic commands with dry-run guardrails. Includes four drop-in automations—NL->plan executor, CSV bulk provisioning with role->group mapping, account hygiene audits with AI summaries, and change announcements—plus a rapid contractor offboarding example, prerequisites, and security best practices.
