Shell Script Formatting (shfmt)

About

This skill provides comprehensive guidance on configuring shfmt to maintain consistent shell script styles across development teams. It covers various configuration methods including .shfmt.toml files, EditorConfig integration, and command-line flags, while offering specific patterns for Bash and POSIX compliance. It is particularly useful for setting up CI/CD pipelines, pre-commit hooks, and IDE-compatible formatting rules to ensure high-quality, readable code in shell-heavy projects.
