Shell Scripts Best Practices (Community)
Comprehensive best practices guide for shell scripting, designed for AI agents and LLMs. Contains 49 rules across 9 categories, prioritized by impact from critical (safety, portability) to incremental (style). Each rule includes detailed explanations, real-world examples comparing incorrect vs. correct implementations, and specific impact metrics.
When to Apply
Reference these guidelines when:
- Writing new bash or POSIX shell scripts
- Reviewing shell scripts for security vulnerabilities
- Debugging scripts that fail silently or behave unexpectedly
- Porting scripts between Linux, macOS, and containers
- Optimizing shell script performance
- Setting up CI/CD pipelines with shell scripts
Rule Categories by Priority
