The Silver Searcher (often referred to as ag) is a fast, open-source command-line code-searching tool, designed as a faster alternative to ack, with a focus on programming-related searches and integration with ignore files. Ag is quite stable now. Most changes are new features, minor bug fixes, or performance improvements. It's much faster than Ack in my benchmarks. Ack and Ag found the same results, but Ag was 34x faster (3.2 seconds vs 110 seconds). My ~/code directory is about 8GB. Thanks...
