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. ISC open source license since Sept. 2014.
AGREP - an approximate GREP.
Fast searching files 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.
For Glimpse and WebGlimpse - AGREP is an essential part of them - see

Approximate Pattern Matching GREP -- Get Regular Expression
Usage:
AGREP [-#cdehi[a|#]klnprstvwxyABDGIRS] [-f patternfile] [-H dir] pattern [files]
-# find matches with at most # errors -A always output filenames
-b print byte offset of match
-c output the number of matched records -B find best match to the pattern
-d define record delimiter -Dk deletion cost is k
-e for use when pattern begins with - -G output the files with a match
-f name of file containing patterns -Ik insertion cost is k
-h do not display file names -Sk substitution cost is k
-i case-insensitive search; ISO <> ASCII -ia ISO chars mapped to lower ASCII
-i# digits-match-digits, letters-letters -i0 case-sensitive search
-k treat pattern literally - no meta-characters
-l output the names of files that contain a match
-n print line numbers of matches -q print buffer byte offsets
-p supersequence search -CP 850|437 set codepage
-r recurse subdirectories (UNIX style) -s silent
-t for use when delimiter is at the end of records
-v output those records without matches -V[012345V] version / verbose more
-w pattern has to match as a word: "win" will not match "wind"
-u unterdruecke record output -x pattern must match a whole line
-y suppresses the prompt when used with -B best match option
@listfile use the filenames in listfile <1>23456Q
