ripgrep (rg)
Modern grep replacement written in Rust. Respects .gitignore, searches hidden files optionally, supports PCRE2, and is significantly faster on large codebases.
PCRE
PCRE2 syntax reference — character classes, quantifiers, anchors, groups, lookarounds, backreferences, flags, and advanced features used in grep, sed, nginx, PHP, and dozens of other tools.
grep
Search files and streams using fixed strings, extended regex, or PCRE. Covers all major flags, context, recursive search, and pipeline patterns.
