Text Editing with Nano

Introduction to Nano Text Editor

Introduction

Nano is a versatile and easy-to-use text editor that is widely used in command-line environments, particularly on Unix-based systems. It is well-known for its simplicity, making it an excellent alternative for both beginners and professionals who need to edit text files in a terminal quickly. This editor operates on a WYSIWYG(What You See Is What You Get) principle. It builds upon the features of UW Pico, enhancing its ease of use. In contrast to editors like Vim, Nano doesn't have different modes. It offers a simple Graphical User Interface (GUI) that enables users to directly interact with the text, eliminating the need to switch between modes like in Vim.

Additionally, at the bottom of the Nano window, you'll find a list of shortcut keys for your reference. All commands in Nano are indicated with either the caret symbol (^) for the Ctrl key or the letter M for the Alt key. For example, when you see ^J, it means you should simultaneously press the Ctrl and J keys. To access a complete list of commands, simply type Ctrl+G.

To Save a File

After pressing the Ctrl+o, it will ask you to enter a filename. If you want to save your changes in a new file or create a new one, you should provide a different name. However, if you wish to retain the existing file, you can keep the filename as it is.

Once you hit the Enter key, if you've changed the filename, it will save the file with the new name. If you haven't made any changes to the filename, it will save the modifications to the existing file.
