How to Use Nano Editor in Linux: Simple Guide

Use the nano command followed by a filename to open or create a file in the nano text editor. Inside nano, type your text, then press Ctrl + O to save and Ctrl + X to exit.

Syntax

The basic syntax to open or create a file with nano is:

• nano filename: Opens the file named filename or creates it if it doesn't exist.
• Ctrl + O: Saves the current file.
• Ctrl + X: Exits nano.
• Ctrl + K: Cuts the current line.
• Ctrl + U: Pastes the cut line.

bash

nano filename

Example

This example shows how to create a file named example.txt, write text, save it, and exit nano.

bash

nano example.txt

Output

The nano editor opens with a blank screen or the contents of example.txt if it exists.

Common Pitfalls

Beginners often forget to save changes before exiting, losing their work. Remember to press Ctrl + O to save, then Enter to confirm the filename, before pressing Ctrl + X to exit.

Another mistake is typing nano without a filename, which opens a blank buffer that won't save unless you specify a filename when saving.

bash

Wrong way:
nano
# Type text and press Ctrl + X without saving

Right way:
nano myfile.txt
# Type text, press Ctrl + O, Enter to save, then Ctrl + X to exit
