gulp‑shell is a small Gulp plugin that lets developers run arbitrary shell commands (or templated commands) as part of their build pipelines, providing options for working directories, environment variables, output handling, and error customization. Its primary audience is front‑end or general JavaScript developers who already use Gulp for task automation and need an easy way to invoke command‑line tools without leaving the Gulp workflow. (It is intended for responsible use—executing shell commands via Gulp should be limited to simple, well‑controlled operations.)
