Ripgrep Recursive Search Tool

Ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, it respects gitignore rules and skips hidden files and directories. Written in Rust, it combines the performance benefits of memory-mapped file reading with SIMD-accelerated searching on x86_64 and ARM architectures. Benchmarks consistently show it outperforming grep, ag, and other popular search tools by significant margins, often achieving speeds several times faster when scanning large codebases. The tool uses Rust's regex engine which supports Unicode character classes, look-around assertions, and backreferences where supported. It provides automatic detection of file encodings including UTF-8 and UTF-16 with BOM, enabling accurate searching across diverse file types without manual configuration. Beyond simple pattern matching, it supports searching within compressed archives, replacement operations with capture groups, and JSON output mode for programmatic consumption. The tool has accumulated over 65,000 GitHub stars and is included by default in many Linux distributions and package managers. Major technology companies rely on it for daily development workflows, CI pipeline text processing, and large-scale codebase analysis. It ships with sensible defaults that require no configuration for most use cases, yet offers extensive command-line flags for advanced scenarios including custom file type definitions, configurable ignore files, and multi-threaded searching with adjustable thread counts. The project maintains active development with regular releases improving performance and adding features like hyperlink support for search results.
