agrep (approximate Grep ) is a Fuzzy String Searching program, developed by Udi Manber and Sun Wu between 1988 and 1991, for use with the Unix operating system. It was later ported to OS/2 , DOS , and Windows . It selects the best-suited algorithm for the current query from a variety of the known fastest (built-in) String Searching Algorithm s, including Manber and Wu's Bitap Algorithm based on Levenshtein Distance s. agrep is also the Search Engine in the indexer program GLIMPSE . It is free for private and non-commercial use only, and belongs to the University of Arizona. A more recent agrep is the command-line tool provided with the TRE regular expression library. TRE agrep is more powerful than Wu-Manber agrep since it allows weights and total costs to be assigned separately to individual groups in the pattern. It can also handle Unicode. Unlike Wu-Manber agrep, TRE agrep is licensed under the GNU LGPL . EXTERNAL LINKS
