The Silver Searcher is a free and open source, cross platform source code searching tool similar to ack (a grep-like tool for programmers) but faster. It runs on Mac, Linux and Windows operating systems.
The major difference between the silver searcher and ack is that the former is designed for speed, and benchmark tests prove that it is indeed faster.
If you spend a lot of time reading and searching through your code, then you need this tool. It aims at being fast and ignoring files that you don’t want to be searched.
