My name is Mar Christian Contreras. I am a student currently attending CSUF. This is my website that holds all of my coding projects.
Link to this github project can be located here.
This project is the compression of the GREP program into less than 400 lines of code. It first involved having to read and understand the code in order to be able to strip and condense the code.
Usage: grep 'text' file.txt
