Introducing Bun Shell: Running Shell Scripts in JavaScript and TypeScript

The text discusses the challenges of running shell scripts in JavaScript and introduces the Bun Shell, a new experimental embedded language and interpreter in Bun that allows cross-platform shell scripts to be run in JavaScript and TypeScript. It addresses the issues of different shell syntaxes, commands, and startup times, offering a solution that integrates seamlessly with JavaScript and provides features like variable usage, redirection, piping, and built-in commands. The Bun Shell is designed as a drop-in replacement for simple shell scripts and is available in Bun for Windows, macOS, and Linux, making it a powerful tool for running scripts and powering "package.json" scripts in "bun run" on Windows.
