The one thing I wish more of these comparison tables had was licensing info, so for those like me who are curious: 1. GNU grep - GPLv3+ 2. ack - Artistic License v2.0 3. ag (aka silver searcher) - Apache License 2.0 4. git-grep - GPlv2+/LGPLv2.1+ 5. rg - MIT license So with maybe the exception of rg, all are gpl compatible, that's great news.
I'm going to be making a new chart that is more about features than command flags. I'll include the licensing information. Thanks. https://github.com/beyondgrep/website/issues/80
