How to start another mode using Emacs on the command line?

Question

Is there a way to start another emacs mode using the command line? For example, is it possible to run emacs as follows?

emacs --org-mode # to start orgmode emacs --python-mode # to start python mode 

I can just run emacs to enter “Mx org-mode” after that, but I wonder if I can start different modes.

Answer 1

You can call functions with the -f argument, therefore, to start use in org-mode:

 emacs -f org-mode
