GREP Options

--max-count=number of matches before stopping search
--exclude=*.txt  with -r option

Note: Lookahead and lookbehind are Perl-style regular expression elements, so you'd have to use Perl directly, or GNU grep with the -P option, which then interprets Perl regex.

grep -o pattern file.txt **shows only the matched string** 
grep -bn pattern file.txt **shows row and col**  
grep -v pattern file.txt **inversion**
