Getting started with Nano

Nano is a popular open-source command-line text editor that has been in development since 1999. It is designed to be simple and user-friendly, making it an ideal choice for users who are new to the world of Linux or command-line interfaces. Nano is available on a wide range of operating systems, including Linux, macOS, BSD, and even Windows.

Nano’s user interface is designed to be intuitive and easy to use. It provides a simple command-line interface with a menu bar at the bottom of the screen, displaying a list of commands that can be accessed using keyboard shortcuts. The text editor also supports syntax highlighting for various programming languages, making it an ideal choice for developers.

One of the main advantages of Nano over other text editors is its small size and minimal system requirements. This makes it an ideal choice for users who want a simple and lightweight text editor that doesn’t consume too many system resources.

Installing Nano

The first step to getting started with Nano is to install it on your system. Nano is usually pre-installed on most Unix-based systems, but if it is not, you can install it using your system’s package manager.

On CentOS or Red Hat-based systems, you can use the following command:

sudo dnf install nano 

Opening a file

Once you have installed Nano, you can open a file by running the following command:

nano filename 

This will open the file named “filename” in Nano. If the file does not exist, Nano will create a new file with that name.

Use “sudo” to edit files in privileged mode.

After opening a file in Nano, you can start editing text. To navigate use up, down, left, and right arrow keys. Nano provides basic editing capabilities such as cutting, copying, pasting, and undoing changes. You can use the following keyboard shortcuts to perform these actions:
