[FSOD] Help with a command?

Hello, i've been trying to figure it out, and I can't figure out how to code it properly to work with FSOD...

I'm looking for a code that will allow the user to type like, "/set wizard", and then the tops gear for a wizard will be put in his inventory...

I don't mind making the code for all classes or adding more items myself, I was just wondering if someone could help me get the very basics of this code to work?

Much appreciated, thank you.
