Bash Defensive Patterns
Built for developers who've been burned by shell scripts failing in production. Implements bash strict mode, proper error trapping, and variable quoting patterns that prevent the usual disasters. Covers atomic file operations, signal handling for background processes, and idempotent script design. The argument parsing and logging templates alone will save you from reinventing wheels. Most valuable for CI/CD pipelines and system automation where a script failure at 2 AM costs real money. Takes the guesswork out of defensive bash programming with patterns that actually work in the wild.
