Plugins (Optional, Good to have!)

    1
    git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
  • zsh-autosuggestions - It suggests commands as you type based on history and completions.

    1
    git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Activate the plugins

  • In ~/.zshrcfile replace the line starting with plugins=to below line.
    1
    plugins=( git zsh-syntax-highlighting zsh-autosuggestions)
