Linux Text Editors - Nano vs Vim

In Linux, configuration files play a critical role in system operation, especially on servers that often lack a graphical user interface (GUI). To modify these files, you need a terminal-based text editor. Among the many options, Nano and Vim stand out as the most commonly used editors.

While Nano is beginner-friendly, Vim offers advanced functionality and a steeper learning curve. Here’s a breakdown of their key features and usage tips.
