Ubuntu 4

The Nano text editor is a simple, user-friendly text editor that comes pre-installed on Unix-based operating systems like Linux and MacOS. It’s a great tool for beginners due to its simplicity and straightforward commands. This article will guide you through the process of using the Nano text editor in a terminal.

Quick Answer

The Nano text editor is a user-friendly tool that allows you to edit text files in a terminal. It can be opened with the nano command followed by the filename, and closed with Ctrl + X. You can navigate through the text using arrow keys, delete text with the Backspace key, and save changes with Ctrl + O. Nano also has features like searching text, cutting, copying, and pasting, displaying line numbers, and customizing its behavior with a .nanorc file.

Opening and Closing Nano

To open Nano with a specific file, use the nano command followed by the filename:

nano filename

If the file exists, Nano will open it. If it doesn’t, Nano will create a new file with the given name.

To close Nano, press Ctrl + X. If you’ve made changes, Nano will ask if you want to save them. Press Y to save or N to discard changes.

Editing Text

Once you’ve opened a file, you can start typing immediately. Use the arrow keys to navigate through the text. To delete text, use the Backspace key. To delete entire lines, move the cursor to the line and press Ctrl + K.

Saving Changes

To save changes without exiting, press Ctrl + O (that’s the letter O, not zero). Nano will display the filename at the bottom of the screen. Press Enter to save with the same name, or type a new name to save as a different file.

Searching Text

Nano includes a search function. Press Ctrl + W to open the search prompt, then type your search query and press Enter. Nano will highlight the first instance of your query. Press Ctrl + W again to find the next instance.

Cut, Copy, and Paste

To cut text, move the cursor to the beginning of the text you want to cut, press Ctrl + K to cut the whole line, or Alt + 6 to copy the line. Then, move the cursor to where you want to paste the text and press Ctrl + U.

Line Numbers

To display line numbers in Nano, use the -c option when opening a file:

nano -c filename

Or, press Alt + N while Nano is open.

Wrapping Text

By default, Nano wraps long lines of text. To disable this, use the -w option:

nano -w filename

Or, press Alt + $ while Nano is open.

Customizing Nano

Nano’s behavior can be customized by creating a .nanorc file in your home directory. This file can contain various set and unset commands to enable or disable features. For example, to permanently enable line numbers, add this line to your .nanorc file:

set linenumbers
