Ubuntu Association Files with Apps Using CLI

#ubuntu #defaultapp #fileextension #cli #changedefaultapp #openwith

Get mimetype from file:

  • xdg-mime query filetype /home/user/test.jpg

Check the default program for a mimetype:

  • xdg-mime query default image/jpeg

Set an association:

  • xdg-mime default gpicview.desktop image/jpeg

Example:

  • xdg-mime query filetype /home/bob/Downloads/vid1.avi
  • xdg-mime query default video/x-msvideo
  • xdg-mime default vlc.desktop video/x-msvideo

Check all user mimetypes:

  • scite ~/.local/share/applications/mimeapps.list

Open a file with default app:

  • xdg-open /home/user/test.jpg

 

ask and choose default app (another way... but didn't work well with me):

  • mimeopen -d /home/user/test.png
