ripgrep

About

ripgrep (rg) recursively searches directories for a regex pattern while respecting your gitignore rules and skipping hidden and binary files by default. Built on Rust's regex engine with SIMD and literal optimizations, it is generally the fastest search tool available — often 5–30x faster than grep on large codebases while keeping full Unicode support. Supports file-type filtering, compressed-file search, multiline patterns, configurable regex engines (including PCRE2), and replacements. A staple of the modern terminal and the search backend for many AI coding agents.
