Customize ZSH Profile Prompt

# Open ZSHRC profile file
nano ~/.zshrc

# Function to adjust prompt to display current git branch with current directory
function branch_name() {
    git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/\1 /p'
}
setopt PROMPT_SUBST
export PROMPT='%b%F{blue}$(branch_name)%b%f%B%F{white}%1d%f%b %B%F{red}#%b%f '

# Reload ZSH
source ~/.zshrc

docker exec -it <my-container-name> /bin/sh

# Install ZSH and Nano
apt-get update && apt-get install -y zsh
touch ~/.zshrc
echo "export PROMPT='%b%F{white}@docker%f%b %B%F{white}%1d%f%b %B%F{cyan}#%b%f '" >> ~/.zshrc

# Start zsh
zsh
