News: Evil Twin(Part 3) - the Full Bash Script

Hello All,

So to recap in part 1 I went through setting up the dchp server. Part 2 detailed the bash script. Now in part 3 I will post the entire bash script. I am doing this in its own post because Part 2 is just way to much info on one post IMO.

Here is the script. Please keep in mind this is my first bash script so it might not be perfect but i think it is pretty good and makes life a little easier. I hope you all enjoy!!!!!!

Update!!!!! Github link at the bottom of the post!
