This is a simple tutorial on how to improve the look and feel of your terminal with these three things:

• ZSH: a robust alternative to traditional BASH
• ohmyzsh: an amazing framework for ZSH with many plugins and themes
• zsh-autosuggestions: an advanced plugin that makes command completion suggestions based on previous commands.

The finished product

Step 1:

The first thing to do is to install ZSH. This is default on macOS now, and the shell is located at /bin/zsh. If you're using Linux, however, you'll need to install it through the package manager and run the command:

zsh

in order to go through the first time user setup. Now that ZSH is installed, we have to set it as the default. To do this, run:

chsh -s /path/to/zsh

with /path/to/zsh being either /usr/bin/zsh or /bin/zsh depending on your system.
