How to run Mathematica as a .m file

Question

I've created this Dummy.nb file with the code

x=2
x+3

and exported it as Dummy.m. Whenever I try to run it on the command line with math -run Dummy.m or math -script Dummy.m, a local interactive Mathematica kernel starts up, which is not what I want. It generates this output

Ideally, I would want to run a notebook on the command line, and have the output evaluated for each cell, but my reading of this stack exchange makes me think that this is unlikely. I know this is a basic question, but how do I run my Mathematica code on the kernel properly.

Thank you for answering!

This looks like the common mistake of not making sure cells have been set as initialization cells before exporting to a package. Check your Dummy.m and see if code lines have been commented out (* like this *). — J. M.'s missing motivation, Mar 11 '19 at 06:10
The code was commented out, but then I uncommented it, and it's still not running. — Pineapple, Mar 13 '19 at 09:04

Try saving your commands in a text file, then piping it to math.exe:

more dummy.txt | math.exe
