portmaster -m syntax

[CyberCr33p]

I want only 1 core to be used during ports compile. I see that portmaster has an option -m ( arguments for make )

Any idea what is the syntax to pass argument -j1 ?

Is it:

portmaster --no-confirm -y -a -m j1

or:

portmaster --no-confirm -y -a -m -j1

I guess the first but I am not sure.

Finally none of the commands work. Any idea what is the correct syntax?
