====== Nemo File Manager ======
===== Change "Open in Terminal" =====
If you aren't running Cinnamon, you can't change this in a GUI
- Install Nemo File Manager
* For Ubuntu sudo apt install nemo
- Install dconf-cli
* In Ubuntu sudo apt install dconf-cli
- Run dconf write /org/cinnamon/desktop/applications/terminal/exec "'$terminalname'"
* Substitute $terminalname with command for your Terminal of choice
* For example, for KDE Konsole the command looks like dconf write /org/cinnamon/desktop/applications/terminal/exec "'konsole'"
* For xfce4-terminal it looks like dconf write /org/cinnamon/desktop/applications/terminal/exec "'xfce4-terminal'"
