This article is the 6th day of the Advent Calendar 2021 of Wazaterm, an online Linux terminal for hackers.

Yesterday, I explained how to change the appearance of Wazaterm using its theme options. Today, let's make it even cooler by using Powerline.

What is Powerline? It is something that changes the appearance of the prompt line for a command like the one in the picture below.

It uses a special font, which can be troublesome to install in local consoles and applications, but Wazaterm includes the font by default, so you can use it just by installing the package.

$ sudo apt update
$ sudo apt install powerline

The powerline package comes with binding, so add it.

$ echo "source /usr/share/powerline/bindings/tmux/powerline.conf" >> .tmux.conf

Then reload .tmux.conf.

$ tmux source-file ~/.tmux.conf

Now you would see like this. it's very cool, isn't it?
