5 Essential macOS Terminal Settings to Configure Right Away

The macOS Terminal is a powerful tool for developers and power users, providing access to the full range of command-line capabilities. While it comes with a range of default settings, customizing the Terminal can significantly enhance your workflow, making it more efficient and enjoyable to use. Let's dive into the 5 essential macOS Terminal settings you should configure right away to maximize your development environment.

Choosing Your Default Shell: Zsh vs. Bash

One of the first steps in configuring your macOS Terminal is selecting the right shell. As of macOS Catalina, Zsh is the default shell replacing Bash. Both shells have their merits, and choosing the right one for you can improve your efficiency in using the Terminal.

Zsh (Z shell)

Zsh is highly customizable and can enhance your productivity with features like superior tab completion, spelling correction, and the ability to expand variables. Additionally, Zsh supports plugins and themes through frameworks like Oh My Zsh, allowing for extensive customization.

To set Zsh as your default shell, you can use the following command:

1chsh -s /bin/zsh
2

Bash

Bash has been the go-to shell for many years and is known for its robustness and compatibility. If you have scripts that rely on Bash-specific syntax, you might prefer to stick with this shell. You can set Bash as your default shell with:

1chsh -s /bin/bash
2

Tip: Evaluate what features you need and experiment with both shells to see which aligns best with your development needs. Explore in-depth comparisons and tutorials on using Zsh vs. Bash.

Enable Syntax Highlighting

Syntax highlighting in Terminal can vastly improve readability, helping you to quickly spot errors and parse complex commands. To enable syntax highlighting, especially if you opt for Zsh, installing tools like Zsh syntax highlighting plugins can be beneficial.

With Oh My Zsh, enabling syntax highlighting is straightforward. First, ensure you have Oh My Zsh installed:

1sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
2

Next, install the syntax highlighting plugin:

1git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
2

Add it to your plugins in .zshrc:

1plugins=(git zsh-syntax-highlighting)
2

Restart your terminal to see the highlighting in action. There's also a robust ecosystem of Bash highlighting tools, such as bash-git-prompt and others, ensuring both shells can cater to your needs.

Setting Up a Custom Theme

A well-designed theme isn't just about aesthetics—it can improve the clarity of your Terminal output, help differentiate environments, and even reduce eye strain. The popular Oh My Zsh framework comes with a variety of themes to choose from.

You can switch themes by editing the ZSH_THEME variable in your .zshrc file. For instance, to use the popular agnoster theme:

1ZSH_THEME="agnoster"
2

Bash users can customize their prompt with theme elements and several configurations to suit their visual preferences. For detailed guides, consider checking resources like How to Customize Your Prompt and Terminal Theme.

Adjusting Font and Colors for Readability

Selecting the right font and color scheme not only helps reduce visual fatigue but also enhances the legibility of code and logs. Here’s how you can adjust these settings:

1. Open Terminal Preferences: Press Cmd + , while in the Terminal or navigate via the menu.

2. Profiles: Under the Profiles tab, access a variety of presets. Customize your profile by selecting a preferred color scheme. Dark themes like Solarized Dark are popular for reducing glare.

3. Font Customization: Within Profiles, look for the Text tab. Here, you can change the font face and size. Monospaced fonts like Menlo, Monaco, or Fira Code (with ligatures support) are recommended for code.

Note: Play around with these settings and find the perfect combination of colors and font size that feels comfortable for long coding sessions.

Configuring the Prompt to Display Useful Information

A well-set-up prompt can provide valuable information at a glance, such as the current directory, the status of version control systems, and user permissions. Oh My Zsh themes like agnoster or powerlevel10k are fantastic for offering informative, customizable prompts.

For those not using Oh My Zsh, you can manually configure PS1 in your .bashrc or .zshrc with variables to display info such as:

1PS1="\u@\h \W \$ "
2

• \u - Username
• \h - Hostname
• \W - Current working directory

If you're interested in taking terminal prompts to the next level, the GitHub repository of Powerlevel10k offers extensive customization options for Zsh users.

Additional Terminal Configurations

Though we've focused on five primary settings, there are numerous other customizations and configurations that can vastly improve your Terminal experience. These include:

• Command History: Customizing how long and how much history the terminal retains. Experiment with HISTSIZE and HISTFILESIZE to suit your needs.

• Aliasing Commands: Create shortcuts with aliases to simplify frequently-used commands. For example, alias ll='ls -alF' for a detailed list view.

• Environment Variables: Manage environment variables to utilize different software package versions with export JAVA_HOME=/path/to/java.

Conclusion

By taking the time to configure your macOS Terminal, you can optimize it for maximum efficiency and comfort, tailoring it to your specific development needs. From selecting the ideal shell, adding syntax highlighting for better code readability, to customizing the visual aspects like theming and fonts, these changes can greatly enhance your productivity.
