Can I install Godot Engine using Command Line?

Answer adapted from here: https://cialu.net/install-godot-game-engine-on-fedora-or-ubuntu/

First, download the appropriate version for your system (32 bit or 64 bit) from the Godot Download Page.

Open a Terminal window and enter:

unzip Godot_v2.1-stable_x11.64.zip

After, move the executable to /opt folder:

sudo mkdir /opt/Godot/

sudo mv Godot_v2.1-stable_x11.64 /opt/Godot/Godot

And make it executable:

sudo chmod +x /opt/Godot/Godot

Then, create and edit a launcher for Godot executable:

cd ~/.local/share/applications/

nano godot.desktop

Populate the .desktop file, writing this in nano, saving with CTRL-O and exiting with CTRL-X:

[Desktop Entry]
Name=Godot Engine

GenericName=Libre game engine
Comment=Multi-platform 2D and 3D game engine with a feature rich editor
Exec=/opt/Godot/Godot -pm
Icon=godot
Terminal=false
Type=Application
Categories=Development;IDE;

And now you can launch Godot from your desktop system. If you want to customize the icon, just put the Godot icon in your theme and name it godot.

My preferred way of installing software(If it's available):

sudo snap install godot
