Install Zsh

First, ensure that Zsh is installed on your system. You can install it using the following commands:

sudo apt update
sudo apt install zsh

Set Zsh as Default Shell

chsh -s (curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh

Install Zsh Autosuggestions

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

nano ~/.zshrc

Find the line that starts with plugins=(...) and add zsh-autosuggestions inside the parentheses. It should look something like this:

plugins=(git zsh-autosuggestions)

Then set ZSH_THEME="powerlevel10k/powerlevel10k" in your .zshrc:

nano ~/.zshrc

ZSH_THEME="powerlevel10k/powerlevel10k"
