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.
