word count command line app (coding-challenge)

My solution to this challenge https://codingchallenges.fyi/challenges/challenge-wc

Installation

1. clone this repository onto your machine
2. run npm i -g to install the script globally
3. to use my-wc:
   • cd <THE FOLDER CONTAINING THE FILE YOU WOULD LIKE INFO ON>
   • (optional) run pwd to check that you are in the desired location
   • run my-wc <FILE NAME> to print the number of line, words, and bytes followed by the file name.
   • run my-wc <FILE NAME> -l to print the number of lines only
   • run my-wc <FILE NAME> -w to print the number of words only
   • run my-wc <FILE NAME> -c to print the number of bytes only

functional requirements

TODO

• multpile files can be processed at ones
