rg

A command-line search tool that recursively scans directories for regex patterns with extreme speed and smart default filtering.

ripgrep (rg) is a line-oriented search utility built in Rust that combines the user-friendly defaults of The Silver Searcher with performance that outpaces GNU grep. It accelerates development workflows by automatically respecting your .gitignore rules and skipping hidden or binary files (saving you from searching through massive node_modules or build directories). Under the hood, it leverages a highly optimized regex engine, SIMD acceleration, and parallel directory traversal to scan millions of lines of code in milliseconds.
