Is it possible to have a script delete a row if it doesn't have something in column B or F

I am looking for a script that will look at row B and F, and if there is nothing in one or the other it will delete the row... Is this possible?

So in English, if There is something in B but not in F it will be left alone, and visa versa...

Also, is there a way to make it so that if there is something in B, to copy something from one cell down up in N, then delete the row under it?

Attached is a workbook I am working with so you have an idea of what I'm trying to do.

Thanks.
