Approximate GREP or AGREP is a utility that searches text input files such as source code for records containing strings which either exactly or approximately match a pattern. Approximate matching allows finding records that contain the pattern with several errors including substitutions, insertions, and deletions.

AGREP supports many kinds of queries including arbitrary wild cards, sets of patterns, and in general, regular expressions (RE). It also supports most of the options supported by the GREP family plus several more.
