ZSH & Oh my ZSH

ZSH is a powerful command interpreter, better than bash. If you use it, you can improve it with Oh my ZSH which is configuration for ZSH.

Install zsh

sudo apt install -y zsh

Install oh-my-zsh

sh -c "$(curl -fsSL"
If you accept to use ZSH, you need to logout to enable it.
If your shell don't persist you can add this line to ~/.bashrc to enable it.
echo 'exec zsh' >> ~/.bashrc

Customize with theme

With Oh my ZSH, you can use themes to have beautiful terminal, check available themes here:, I use pmcgee

To install a new theme, just edit .zshrc

vim ~/.zshrc

Search ZSH_THEME at the top of file and update value


Update new configuration

source ~/.zshrc


eza a replacement for ‘ls’

sudo apt update
sudo apt install -y gpg

Install eza

sudo mkdir -p /etc/apt/keyrings
wget -qO- | sudo gpg --dearmor -o /etc/apt/keyrings/gierens.gpg
echo "deb [signed-by=/etc/apt/keyrings/gierens.gpg] stable main" | sudo tee /etc/apt/sources.list.d/gierens.list
sudo chmod 644 /etc/apt/keyrings/gierens.gpg /etc/apt/sources.list.d/gierens.list
sudo apt update
sudo apt install -y eza

Make alias in your PATH

vim ~/.zshrc
alias ls="eza"
alias ll="eza -al"
alias la="eza --long --all"
source ~/.zshrc

Now you can use eza with ls.
