When I need to restart moksha I do it via htop. I look up the /usr/bin/enlightenement and then kill process.

This is my way. I believe there are more methods...

EDIT: enlightenment_remote -restart
This command should be the best answer for your question
BTW, enlightenment_remote --help will show you all commnands
