Grep - Finds lines that match entered patterns

Package includes the GNU 'grep,' 'egrep,' and 'fgrep,' which find lines that match entered patterns. By default, grep prints the matching lines.

GNU grep is based on a fast lazy-state deterministic matcher (about twice as fast as the standard Unix grep) hybridized with a Boyer-Moore-Gosper search for a fixed string that eliminates impossible text from being considered by the full regexp match without having to look at every character; the result is usually many times faster that UNIX 'grep' or 'egrep.'
