The easiest way to install is using homebrew:

brew install MisterTea/et/et


For Ubuntu, use our PPA:

sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:jgmath2000/et
sudo apt-get update
sudo apt-get install et


For debian, use our deb repo. For stretch:

echo "
deb https://mistertea.github.io/debian-et/debian-source/ stretch main
" | sudo tee -a /etc/apt/sources.list
curl -sS https://mistertea.github.io/debian-et/et.gpg | sudo apt-key add -
sudo apt update
sudo apt install et

Other Linux

Download and install from source (you may need some dependencies):

wget https://github.com/MisterTea/EternalTerminal/archive/master.zip
unzip master.zip
cd master
mkdir build
cd build
cmake ../
sudo make install


ET works under WSL (Windows Subsystem for Linux), but you must be running xenial or higher. See this issue for details: https://github.com/Microsoft/BashOnWindows/issues/482

As long as you are running Xenial, you can follow the ubuntu instructions for installation.
