ripgrep

It searches text files recursively, matching lines against regular‑expression patterns while automatically respecting .gitignore entries, skipping hidden paths, and ignoring binary files unless explicitly requested. The tool runs on Windows, macOS and Linux, and is distributed as prebuilt binaries for each release. Users can adjust its filtering behavior with flags such as `-uuu` to disable all automatic exclusions.

The command‑line interface is designed for developers and system administrators who need fast, reliable searching within source trees or large collections of files. It supports Unicode matching, word‑boundary constraints, and can be configured via files and shell completions. Benchmarks in the documentation show it outperforms several alternative search utilities on typical codebases and large single‑file workloads.

Ripgrep is released under a dual MIT/UNLICENSE license, with source code hosted on GitHub and available through the Rust crate ecosystem. Continuous integration ensures stable builds, and documentation includes installation guides, a user guide, FAQs, and references to regex syntax.
