How to change default applications with Terminal

I want to change the default applications to /dev/null (to not open things in applications that are not allowed). How can I do this programmatically?

You'll need to explain what you mean here. Are you looking at preventing opening certain files, certain applications, or a combination? Maybe give an example.

Hello Toz,
Thank you first off for all you have done.

An example is: with Teams For Linux i am trying to open a "Edit in browser" link and suddenly the terminal opens, probably because I dont have a browser installed... So I want to prevent those actions. Which I can do at least in basic form with going into default applications and setting the 4 most important categories to /dev/null. But I'd like to know if there is a better way.

Ive looks into mime info slightly but even with changed default apps I cannot see those applied changes anywhere on the filesystem.

For more specifics: https://github.com/daanselen/ntos where I store my project with xfce at its centre.

Thank you.

Unfortunately, Teams is a closed source application meaning its not known how it opens links in a browser. You could look at creating a overriding mime association to deal with something like this, but unfortunately that doesn't work. I tried.

I think its regarding the mime types yeah. But for now I will leave it for what it is.
