In this lesson, we’ll compare two popular shell-based editors—GNU Nano and Emacs—and explore their features, keyboard shortcuts, and use cases. While Vi is powerful, Nano and Emacs can be more approachable for newcomers on Linux systems.

​
Why Choose GNU Nano?

GNU Nano is designed for simplicity: all input goes directly into the document, and commands use the Control (Ctrl) or Meta (Alt or Command on macOS) keys. Key features of Nano include:
  • Undo and redo
  • Syntax coloring
  • Interactive search and replace
  • Auto-indentation
  • Line numbers
  • Word completion
  • File locking and backup files
  • Internationalization support

Nano Keyboard Shortcuts

Most Nano commands appear at the bottom of the interface, but here are some essentials:

Emacs: A Programmable Editor and IDE

Emacs is a highly extensible editor that can function as a full IDE, email client, news reader, or RSS client. Like Nano, typing inserts text directly, but uses more keyboard-driven navigation. Core capabilities of Emacs include:
  • Syntax highlighting and indentation
  • Integrated compiling, running, and testing
  • Powerful undo/redo and version control integration
  • Extensible architecture via Emacs Lisp
  • Configuration as email, news, or RSS client
The image is a text description of Emacs, highlighting its features as a text editor, IDE, and its ability to be configured as an email, news, or RSS client.
Emacs starts with emacs filename and provides built-in tutorials under Ctrl+h t. Explore packages via M-x package-list-packages.
