Hi.

Possibly of some help:

Code:

NAME
       agrep - search a file for a string or regular expression, with
       approximate matching capabilities

DESCRIPTION
       agrep searches the input filenames (standard input is the default, but
       see a warning under LIMITATIONS) for records containing strings which
       either exactly or approximately match a pattern.  A record is by
       default a line, but it can be defined differently using the -d option
       (see below).  Normally, each record found is copied to the standard
       output.  Approximate matching allows finding records that contain the
       pattern with several errors including substitutions, insertions, and
       deletions.  For example, Massechusets matches Massachusetts with two
       errors (one substitution and one insertion).  Running agrep -2
       Massechusets foo outputs all lines in foo containing any string with at
       most 2 errors from Massechusets.

-- man agrep, q.v.

The agrep code is in repositories for CentOS, Debian, Ubuntu, OpenSuSE, etc.

Best wishes ... cheers, drl

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
