>>154 20100722: BSD grep has been imported to the base system and it is built by default. It is completely BSD licensed, highly GNU-compatible, uses less memory than its GNU counterpart and has a small codebase. However, it is slower than its GNU counterpart, which is mostly noticeable for larger searches, for smaller ones it is measurable but not significant. The reason is complex, the most important factor is that we lack a modern and efficient regex library and GNU overcomes this by optimizing the searches internally. Future work on improving the regex performance is planned, for the meantime, users that need better performance, can build GNU grep instead by setting the WITH_GNU_GREP knob. 20120628: The sort utility has been replaced with BSD sort. For now, GNU sort is also available as "gnusort" or the default can be set back to GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be installed as "bsdsort".
