Ripgrep vs grep: Why Switch

Ripgrep is dramatically faster.

Speed

ripgrep (rg) is a faster, smarter grep. The discipline is using rg interactively where its features pay off and falling back to grep where portability matters.

• Ten to a hundred times faster on large codebases. Performance dominates grep on large directory trees. Interactive search becomes interactive rather than wait-and-context-switch.
• Multi-threaded by default. ripgrep saturates available cores on modern multi-core machines. Search scales with hardware rather than serialising on one core.
• Optimised for code plus SIMD. Designed for code search; uses SIMD instructions where available. Common patterns are fast on modern CPUs without flag tuning.
• Memory efficient. Large file searches stay memory-efficient. The local machine does not strain on monorepo-scale searches.

Smart defaults

ripgrep's defaults are aligned with modern codebase patterns. .gitignore is respected, binary files are skipped, and language-specific filters are first-class. The defaults match what the engineer actually wants without flag archaeology.

• Skips .gitignore'd files. Build artifacts, dependency directories, and generated files are excluded by default. The search targets source rather than node_modules.
• Skips binary files. Binary files are not searched by default. Output is not garbled with embedded null bytes; results stay readable.
• Most of what you want, faster. Defaults match typical interactive use. Useful output arrives without remembering --exclude-dir flags.
• Override plus type filters. -uu includes hidden files and binaries when needed; --type python searches only Python files. Edge cases and language-specific searches are concise rather than verbose.

When grep wins

Despite ripgrep's advantages, grep has its place. Portability and universal availability are grep's strengths; the discipline picks each where it fits rather than defaulting to one tool everywhere.

• Portable scripts. Scripts that run on many machines benefit from grep. Every Linux machine has grep; ripgrep is per-machine; portable scripts cannot assume rg.
• grep is everywhere. SSH into any server and grep is there. ripgrep installation is opt-in; production hosts and incident-response shells often do not have it.
• Check before assuming rg. The team's discipline checks. If rg is reliably available across the script's targets, use it; otherwise grep is the safe choice.
• Default rg interactively, grep in scripts. Engineer-facing interactive search uses rg for speed and smart defaults; automation-facing scripts use grep for portability.
