agrep (approximate grep) is an open-source approximate string matching 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 algorithms, including Manber and Wu's bitap algorithm based on Levenshtein distances.
agrep is also the search engine in the indexer program GLIMPSE. agrep is under a free ISC License.
Alternative implementations
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 a 2-clause BSD-like license.
FREJ (Fuzzy Regular Expressions for Java) open-source library provides command-line interface which could be used in the way similar to agrep. Unlike agrep or TRE it could be used for constructing complex substitutions for matched text. However its syntax and matching abilities differs significantly from ones of ordinary regular expressions.

agrep function - RDocumentation
agrep returns a vector giving the indices of the elements that yielded a match, or, if value is TRUE, the matched elements (after coercion, preserving names but no other attributes). agrepl returns a logical vector.
GitHub - Wikinaut/agrep: AGREP - approximate GREP for fast …
AGREP - approximate GREP for fast fuzzy string searching. Files are searched for a string or regular expression, with approximate matching capabilities and user-definable records. Developed 1989-1991 by Udi Manber, Sun Wu et al. at the University of Arizona.
Linux agrep command - Computer Hope
Sep 10, 2024 · agrep searches the input file names (standard input is the default) for records containing strings which either exactly or approximately match a pattern. A record is by default a single line, but it can be defined differently using the -d option (see below).
How to use the agrep () function in base R - R-bloggers
The agrep() function in base R is used for approximate string matching, also known as fuzzy matching. Here’s how to use it effectively: Basic syntax. The basic syntax of agrep() is as follows: agrep( pattern, x, max.distance = 0.1, ignore.case = FALSE, value = FALSE, fixed = TRUE ) Where: pattern: The string pattern you want to match
agrep: Approximate String Matching (Fuzzy Matching)
agrep returns a vector giving the indices of the elements that yielded a match, or, if value is TRUE, the matched elements (after coercion, preserving names but no other attributes). agrepl returns a logical vector.
