How to run Mathematica using Mac Terminal

Question

My question is so trivial and I'm sure most people in here know exactly how to do this, however I still don't know how to run Mathematica in Mac terminal!

I need to use all the cores of my computer in order to get faster results. I open Mathematica in terminal using this command:

/Applications/Mathematica.app/Contents/MacOS/MathKernel

Then when I type math -run "<<test.m" (test is my file's name), nothing happens! Can anybody guide me what to do or refer me to a good refrence with some examples at this?

Answer 1

With a test.m file content of :

Print["Hello World"];

At the kernel:

In[1]:=<<"test.m"                
Hello World

In[2]:=    

Or, as an alternative run the file as a script

./MathKernel -script test.m
