Introduction to the text editor “nano”

The Nano text editor is a popular command-line text editor that is designed to be easy to use and highly customizable. It is widely used by programmers, system administrators, and other users who need a lightweight and efficient text editor for their work.

In this blog post, we will explore some of the key features of Nano and provide examples of some of the most commonly used commands.

Getting started with Nano

To start using Nano, simply open a terminal window and type “nano” followed by the name of the file you want to edit. For example, to edit a file called “example.txt”, you would type:

nano example.txt

Once you have opened a file in Nano, you can start editing it. The cursor will be placed at the beginning of the file, and you can use the arrow keys to move around the text.

GNU nano was designed to be a free replacement for the Pico text editor, part of the Pine email suite from The University of Washington. It aimed to “emulate Pico as closely as is reasonable and then include extra functionality”.

Basic editing commands

Here are some of the most commonly used editing commands in Nano:

  1. Ctrl+O – Write out the current file to disk.
  2. Ctrl+X – Exit the editor.
  3. Ctrl+G – Display the help screen.
  4. Ctrl+K – Cut the current line.
  5. Ctrl+U – Uncut (i.e., paste) the cut line.

Customizing Nano

One of the great things about Nano is that it is highly customizable. You can create your own key bindings, change the color scheme, and even write your own macros to automate common tasks.

To customize Nano, you will need to create a configuration file called “.nanorc” in your home directory. This file can contain various settings and options that will be applied to all instances of Nano.

For example, to set the tab size to 4 spaces, you can add the following line to your .nanorc file:

codeset tabsize 4

Similarly, to change the color scheme, you can add lines like the following:

codesyntax "python" "\.py$"
color green "\<(and|or|not)\>"

This will change the color of the “and”, “or”, and “not” keywords in Python code to green.


Nano is a powerful and highly customizable text editor that can help you work more efficiently on the command line. By learning some of the most commonly used commands, you can quickly become proficient in Nano and take advantage of its many features and options. Whether you are a programmer, system administrator, or just a power user, Nano is definitely worth checking out.
