Enabling Command Autocompletion in ZSH

This guide will help you enable command autocomplete in Zsh using the zsh-autosuggestions plugin. Follow the steps below to get started, and if any issues arise, refer to the troubleshooting tips to help resolve common problems.

Prerequisites

  • Ensure you have Oh My Zsh installed. This helps manage plugins and customize your Zsh experience.
  • If you’re on macOS, Zsh is likely installed by default, but you may need to install Oh My Zsh separately.

To install Oh My Zsh:

1sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Step 1: Update Your .zshrc file

Add zsh-autosuggestions to the plugins array in your .zshrc file to enable it:

Some Text

Once done, run source ~/.zshrc If autocomplete suggestions work, you’re all set! If you see an error like this:

1[oh-my-zsh] plugin 'zsh-autosuggestions' not found

then zsh-autosuggestions might not be installed in the correct location. Continue to the troubleshooting steps below.

Step 2: Troubleshooting: Plugin Not Found

If you encounter the “plugin not found” error, you likely need to install zsh-autosuggestions. Follow these steps to manually install it. For Both Linux and macOS Users:

  • Clone zsh-autosuggestions into the Oh My Zsh custom plugins directory:
1git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Verify the plugins array in .zshrc: Ensure zsh-autosuggestions is still listed in your plugins:

1plugins=(
2  git
3  zsh-autosuggestions
4)

Reload the configuration:

1source ~/.zshrc

This should resolve the vast majority of any errors you might see.

Conclusion

By following these steps, you should now have zsh-autosuggestions enabled, and command autocomplete suggestions will appear as you type. If you have any other questions or run into issues not covered here, feel free to reach out in the comments!
