find - this command examines a directory to find a file
matching some criteria.

grep - it searches for a string or pattern in a file and
display the lines containing the pattern.

sed - it combines work of several filters and perform non
interactive operations on a data stream.

Write a command that will display files in the current directory, in a colored, long format.
