ripgrep : The Fast, Flexible Search Tool

ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

(To disable all automatic filtering by default, use rg -uuu.) ripgrep has first class support on Windows, macOS and Linux, with binary downloads available for every release. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.

Quick Examples Comparing Tools

This example searches the entire Linux kernel source tree (after running make defconfig && make -j8) for [A-Z]+_SUSPEND, where all matches must be words. Timings were collected on a system with an Intel i9-12900K 5.2 GHz

Please remember that a single benchmark is never enough! See my blog post on ripgrep for a very detailed comparison with more benchmarks and analysis.
