Bash Defensive Patterns

Comprehensive guidance for writing production-ready Bash scripts using defensive programming techniques, error handling, and safety best practices to prevent common pitfalls and ensure reliability.

Use this skill when

Writing production automation scripts

Building CI/CD pipeline scripts

Creating system administration utilities

Developing error-resilient deployment automation

Writing scripts that must handle edge cases safely

Building maintainable shell script libraries

Implementing comprehensive logging and monitoring

Creating scripts that must work across different platforms

Do not use this skill when

You need a single ad-hoc shell command, not a script

The target environment requires strict POSIX sh only

The task is unrelated to shell scripting or automation

Instructions

Confirm the target shell, OS, and execution environment.

Enable strict mode and safe defaults from the start.

Validate inputs, quote variables, and handle files safely.

Add logging, error traps, and basic tests.

Safety

Avoid destructive commands without confirmation or dry-run flags.

Do not run scripts as root unless strictly required.

Refer to resources/implementation-playbook.md for detailed patterns, checklists, and templates.

Limitations

Use this skill only when the task clearly matches the scope described above.

Do not treat the output as a substitute for environment-specific validation, testing, or expert review.

Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
