UniversalCodeGrep is described as '(ucg) is an extremely fast grep-like tool specialized for searching large bodies of source code. It is intended to be largely command-line compatible with Ack, to some extent with ag, and where appropriate with grep' and is an app in the File Management category. There are seven alternatives to UniversalCodeGrep for Linux, Mac, Windows, BSD and Haiku. The best alternative is grep, which is both free and Open Source. Other great apps like UniversalCodeGrep are dnGREP (Free, Open Source), ripgrep (Free, Open Source), The Silver Searcher (Free, Open Source) and ack (Free, Open Source).
Ack is designed as a standalone (one perl file) replacement for 99% of the uses of grep. ack is intelligent about the files it searches. It knows about certain file types, based on both the extension on the file and, in some cases, the contents of the file.
Tiny ack-style file search utility. All arguments constitute the search text. No need to wrap most searches in double quotes. Short & written in Bash - just find & grep: you can edit it easily to suit your liking.
