Oh my zsh plugin must install

In your terminal window install zsh:

sudo apt install zsh

Next we install ohmyzsh:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Then we pull down plugins from GitHub in to zsh plugin directory:

autosuggesions plugin

git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions

zsh-syntax-highlighting plugin

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting

zsh-fast-syntax-highlighting plugin

git clone https://github.com/zdharma-continuum/fast-syntax-highlighting.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/plugins/fast-syntax-highlighting

zsh-autocomplete plugin

git clone --depth 1 -- https://github.com/marlonrichert/zsh-autocomplete.git $ZSH_CUSTOM/plugins/zsh-autocomplete

Finally we need to enable these plugin in .zshrc file

nano ~/.zshrc

Find plugins=(git) and replace with:

plugins=(git zsh-autosuggestions zsh-syntax-highlighting fast-syntax-highlighting zsh-autocomplete)

Finally, close your terminal window and open new terminal. Voila!
