One of the most powerful tools a programmer can use is the Terminal or command line. Whether you’re using macOS, Linux, or Windows, knowing and using Terminal effectively can help you increase your productivity. Here are 7 Terminal tips to help programmers work faster and more efficiently.

1. Using Alias
- For example, instead of having to type git status every time you want to check the status of a repository, you can create an alias like gs.
- Every time you type gs on Terminal, it will automatically replace it with git status.
2. Using Command History
- Press Arrow Up to see the command you used previously.
- Use the history command to view a list of recent commands.
- Search for the previous command with Ctrl + r and enter part of the command.
3. Use ‘Tab’ for auto-completion
- Just type part of a file or folder name and press Tab, Terminal will autocomplete it for you.
4. Use tmux or screen
- These are tools that help you create and manage multiple Terminal sessions in a single window. You can switch between sessions, share sessions with others, and more.
5. Using cat, less and grep
- cat: Displays the contents of a file.
- less: Conveniently browse file contents.
- grep: Searches within a file or command line. For example: grep “programming” filename.txt will find all lines containing “programming” in filename.txt.
6. Customize your Terminal
- Install themes, adjust transparency, or use tools like oh-my-zsh (for Zsh) for increased productivity and a better experience.
7. Learn and use basic commands
- Some basic commands like cd, mkdir, mv, rm, cp help you move and manage files easily on Terminal.
Comparing Terminal and GUI
For many people, graphical user interfaces (GUIs) are often easier and more intuitive to use. However, when we compare Terminal and GUI from a programmer’s perspective, Terminal often offers many advantages:
Speed:
- Terminal: Commands can be executed quickly without having to navigate through multiple menus or windows.
- GUI: Users often have to navigate through multiple dropdown menus, windows, or tabs.
- For example, for Git, using the git clone [URL] command in Terminal is often faster and more efficient than opening a GUI tool, navigating to the clone function, then pasting the URL and selecting the destination folder.
Customize:
- Terminal: Allows you to create aliases, scripts, or combinations of commands to optimize your workflow.
- GUI: Usually limited in customization, and users have to adapt to the available interface.
- For example, you can create a script in Terminal to automatically backup your project, push to Git, and send email notifications whenever there are changes.
Extended functions:
- Terminal: Virtually unlimited. With Terminal, you can combine multiple tools, libraries and create complex data processing chains.
- GUI: Functions are usually predefined and the user can only do what the GUI allows.
- For example, for data processing, you can use Terminal to combine grep, awk, sed commands to filter and transform data flexibly.
But it’s also worth noting that GUIs have their benefits, especially for beginners or those unfamiliar with the command line. Certain tasks like graphic design, video editing, or data visualization are often better served using a GUI.
Security in Terminal
When using Terminal, security is not only important, it’s essential. Here are a few things to keep in mind:
- Limitations on using sudo: Although sudo allows you to perform many administrative tasks, using it carelessly can cause harm to your system.
- Avoid the rm -rf command: This command deletes files and folders without confirmation. If used incorrectly, you may lose important data.
- Be careful with scripts: Do not run scripts from untrusted sources without reviewing their contents first.
- Enhance SSH security: If you use SSH, consider using a tutorial, disabling password logins, and using certificates for enhanced security.
Optimize Terminal Display
To enhance user experience and help you work more efficiently:
- Use readable fonts: Fonts like Fira Code, JetBrains Mono, or Source Code Pro are designed specifically for programming, making your code easier to read.
- Color customization: Using a dark color palette helps reduce eye strain, especially when working at night.
- Using Plugins and Themes: Oh-my-zsh and Powerline are great tools for customizing your interface, adding features, and creating a beautiful Terminal experience.
- Screen Sharing: Use tmux or screen to split the Terminal into multiple windows or panes, allowing you to monitor and work on multiple sessions at once.
- Command line optimization: Display information like current git branch, status, and many other useful information right on the command line.
When you combine security knowledge and display optimization, you will have a safe and efficient Terminal environment that will help improve your productivity.
Install and manage packages from Terminal
For programmers and system administrators, installing and managing software via Terminal is an indispensable skill. This helps optimize time and effort compared to manual downloading and installation.
Homebrew (for macOS):
- Introduction: Homebrew is a package manager for macOS that allows you to install applications and tools that Apple doesn’t include in the operating system.
- Installation: To install Homebrew, open Terminal and enter the following command:
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”
- Use:
- Install a package: brew install [package-name]
- Update package: brew upgrade [package-name]
- Remove package: brew uninstall [package-name]
- Update Homebrew and package list: brew update
apt-get (for Linux, especially Debian-based distributions like Ubuntu):
- Introduction: apt-get is a package management tool for Linux, which helps users install, update, and remove software easily from repositories.
- Use:
- Update package list: sudo apt-get update
- Upgrade all installed packages: sudo apt-get upgrade
- Install a package: sudo apt-get install [package-name]
- Remove package: sudo apt-get remove [package-name]
- Remove package and related configuration: sudo apt-get purge [package-name]
- Search for packages: apt-cache search [keywords]
Notes when using:
When installing and managing packages from the Terminal, you should regularly update your package list and software versions to ensure you are always using the latest and most secure versions. Also, be cautious when adding new repositories to avoid installing untrusted software.
Conclude
Terminal, with its flexibility and power, has become an indispensable tool for programmers and system administrators. Understanding and using Terminal can help you increase productivity, reduce working time and achieve the desired results quickly.
- Increase productivity with tips: Like using keyboard shortcuts, creating aliases for frequently used commands, using command history, and combining commands to optimize workflow.
- Security: Be aware of and practice security measures, such as limiting the use of sudo, avoiding powerful delete commands like rm -rf, and being careful with scripts from unknown sources.
- Optimize display: By customizing fonts, colors, and using plugins and themes, you can create a comfortable and productive working environment.
- Install and manage packages: Using tools like Homebrew for macOS and apt-get for Linux makes installing and updating software quick and easy.
- Comparing Terminal and GUI: While graphical interfaces may be better suited for some tasks, the flexibility and high performance of Terminal often provide superior benefits for those looking to optimize their work.
When you combine all these skills and knowledge, Terminal becomes a valuable tool, helping you reach a professional and optimal level in your work.
