# System /usr/share/applications/ /usr/local/share/applications/ # Flatpak /var/lib/flatpak/exports/share/applications/ # Snap /var/lib/snapd/desktop/applications/ # Local ~/.local/share/applications/
Search for your application in those directories and edit the files, using
root privileges where necessary.
sudo vim /usr/share/applications/org.gnome.Terminal.desktop
Now edit what you need, like the application command to add extra flags:
TryExec=gnome-terminal Exec=gnome-terminal --full-screen Icon=org.gnome.Terminal Type=Application
You can also add environment variables using
Exec=env LANG=en_GB.UTF-8 gnome-terminal --full-screen
Copy it to
~/.local/share/applications if you don’t want to edit the original.
