Advanced Bash automation patterns for production-grade scripts and automation workflows. Covers retry logic, lock files, signal handling, advanced error handling, performance optimization, testing with BATS, and cross-platform compatibility. Use when building automation scripts, deployment tools, CI/CD helpers, or when asking about advanced Bash patterns, script reliability, or automation best practices.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Scripting & Automation
Use the Bash skill (`${HANDBOOK_ROOT}/skills/bash-shell-scripting/SKILL.md`) for baseline shell authoring. This skill owns automation-specific retries, locks, signals, idempotency, deployment workflows, and BATS patterns.
## Guiding Principles
- **"Fail fast, fail clearly"** - Use strict mode, validate early, provide clear error messages
- **"Quotes are your friend"** - Always quote variables unless you explicitly want word splitting
- **"Explicit over implicit"** - Use `local`, `readonly`, clear function names, document assumptions
- **"Security by default"** - Sanitize inputs, use `mktemp`, avoid `eval`, validate file paths
- **"Composition over complexity"** - Small functions, clear separation of concerns, reusable patterns
- **"Observability is essential"** - Structured logging, proper exit codes, error context
- **"Test what you write"** - Use shellcheck, test on multiple platforms, write BATS tests
- **"Format consistently"** - Must pass `shfmt -i 2 -ci -sr -bn` (2-space indentation; prefer ~100-character lines)
## Quick Reference
```bash
# Safety modes
set -euo pipefail # Strict mode (fail-fast)

How to install
mdr add d-padmanabhan/agent-engineering-handbook/scripting-automation@sha256:5f375c28b66e5e8bThe line at the top of this page pins the label git:20260819.d23bb73, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
