<SOLVED> Is it possible/how could I change default software launcher for specific file extensions through the terminal?

Is there a terminal command for me to change the default software for launching specific file extensions or not recommendable/only possible through the desktop environment?

Yes, there is a 2 step process:

1) First you have to find out the MIME type for file with that extension. Open a terminal in a directory where you have such a file and run the command xdg-mime query filetype filename where you replace "filename" with the filename. You can press Tab key to auto-complete partially typed filenames. The command will reply the MIME type of the file.

2) Then find the .desktop file for the program you want to set as default. You can usually find them in /usr/share/applications and by checking the files list of the program's package and getting the name of the .desktop file from that. Then you can run xdg-mime default application mimetype where you replace "application" with the name of the .desktop file (just its filename, not the path) and "mimetype" with the MIME type you got in step 1.

You can see the current default with xdg-mime query default mimetype where your replace "mimetype" with the MIME type you got in step 1.
