How to apply a magic command in all notebooks by default? The case of %matplotlib inline

[kirilllzaitsev]

Is there any way to avoid copy-pasting %matplotlib inline in every notebook and use it by default instead?
What about other magic commands? For tools that don't implement their own .rc configuration file?

Greetings @kirilllzaitsev

You could create any .py file in ~/.ipython/profile_default/startup/ containing

get_ipython().magic('matplotlib inline')
