Vim vs. Vi vs. Nano: Choosing the Right Text Editor for You

Thursday, 12th September 2024

When working in the Linux environment, one of the essential tasks for any cloud or DevOps engineer is editing configuration files, writing scripts, or even developing code directly from the command line. For this, choosing the right text editor is key to efficiency. Among the popular editors available in Linux are Vi, Vim, and Nano. Each has its strengths and caters to different users based on their needs and skill levels. In this blog, we’ll explore the differences between Vim, Vi, and Nano, helping you choose the one that best suits your workflow.

Vi: The Classic Unix Editor

Vi (short for "visual") is the original Unix text editor, and it’s still a go-to tool in many Linux distributions today. It comes pre-installed on almost all Unix-based systems, making it a default choice when other editors aren't available.

Key Features of Vi:

1. Modal Editing: Vi operates in multiple modes:

   • Command mode for navigating and manipulating text.

   • Insert mode for editing and writing.

   • Ex mode for executing commands.

2. Lightweight: Being a small, fast, and efficient editor, it doesn’t consume much system resources.

3. Steep Learning Curve: The lack of modern user-friendly features can make it hard to learn for beginners. Vi’s key commands aren’t always intuitive, so new users often face a steep learning curve.

Why Use Vi:

• Availability: Since it’s available on virtually every Unix system, you can always count on Vi when working in different environments.

• Powerful for Experts: For those who have mastered it, Vi can be a fast and powerful tool.

Vi Commands:

To open a file in Vi:

vi filename

Basic commands in Vi:

• Insert mode: Press i to start editing the file.

• Command mode: Press Esc to return to command mode.

• Save and exit: Type :wq and press Enter.

• Exit without saving: Type :q! and press Enter.

• Delete a line: Press dd in command mode.

Vim: Vi Improved

Vim stands for "Vi Improved" and, as the name suggests, it’s an enhanced version of Vi. While retaining all of the core functionality of Vi, Vim introduces many additional features to make it more user-friendly and powerful for modern-day usage.

Key Features of Vim:

1. Extended Functionality: Vim adds syntax highlighting, multi-level undo, auto-completion, and a robust plugin system, making it suitable for development and configuration editing.

2. Highly Configurable: Vim allows for customization, from simple settings like enabling line numbers to advanced configurations with plugins and custom key bindings.

3. Powerful Search and Replace: Vim’s search and replace functions are extremely powerful, allowing for complex text manipulation.

4. Still Modal: Like Vi, Vim also uses command and insert modes, but it has added functionality in each.

Why Use Vim:

• Rich Feature Set: Vim is a more powerful editor, suitable for both simple and complex tasks, from basic text editing to writing large code files.

• Speed: Once mastered, Vim allows for very fast editing due to its keyboard-centric nature.

• Scripting Support: Vim supports custom scripting with VimScript, enabling advanced automation for repetitive tasks.

Vim Commands:

To open a file in Vim:
