====== 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 <code> sudo apt install nemo </code>
  - Install dconf-cli
    * In Ubuntu <code> sudo apt install dconf-cli </code>
  - Run <code> dconf write /org/cinnamon/desktop/applications/terminal/exec "'$terminalname'" </code>
    * Substitute $terminalname with command for your Terminal of choice
    * For example, for KDE Konsole the command looks like <code> dconf write /org/cinnamon/desktop/applications/terminal/exec "'konsole'" </code>
    * For xfce4-terminal it looks like <code> dconf write /org/cinnamon/desktop/applications/terminal/exec "'xfce4-terminal'" </code>
