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

  1. Confirm the target shell, OS, and execution environment.
  2. Enable strict mode and safe defaults from the start.
  3. Validate inputs, quote variables, and handle files safely.
  4. 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.

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • It is part of a pack with 30 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
