Power shell Newbie

by Feb 19, 2020

I am so desperate and hoping someone can help. I am currently taking a class that requires me to learn power shell in 2 weeks!! Ugh!! 
I need a script that will allow me to pull like minded files into one file space that I can name . If I was to search all my files that contain the word fire I would like to be able to group them into one file for easy access . I am in danger of failing this class as I have no clue how to write this script. I have read numerous books and online tutorials and not one of them touches on this subject. I am begging for anyones help. Thanks so much 

I am a returning adult student full time job and three kids, my professor seems to think I have all the time in the world to work on this. If anyone could help I would be so very grateful!!
