"""Basic Python Cheat Sheet by Filip Kral on 2015/02/16"""
 
"""
Python is a cross-platform, interpreted, object-oriented programming language.
That means you can run it on Linux, Windows, Mac, and other platforms,
you don't need to compile your code to execute it because it is compiled on
the fly, and you can use classes and objects.

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**
