sed code will check 2A3M only from 6th to 9th position in the file.
Quote:
Save the pattern enclosed between \( and \) in a special holding space. Up to nine subpatterns can be saved on a single pattern. The text matched by the subpatterns can be reused later in the same pattern, by the escape sequences \1 to \9. For example, \(ab\).*\1 matches two occurrences of ab, with any number of characters in between.
\(.\{5\}\) Holds first five characters. [COLOR="rgb(255, 0, 255)"]\1[/COLOR] gives the first five characters saved in [COLOR="rgb(255, 0, 255)"]\( \)[/COLOR]
