clone this repository onto your machine
run npm i -g to install the script globally
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
