Nano, the minimalist editor for quick and lightweight editing

1. Why Nano?

Nano is a command line text editor, known for being one of the simplest and most intuitive available in the GNU/Linux world.

It is found in most Linux distributions and is a tool that anyone can use “at first glance.”

At the bottom of the screen is a description of the most commonly used commands, where the symbol ^ represents the Ctrl key and the symbol “M” indicates the Alt key (which was once called Meta and is still called that in Emacs).

For example: ^O means: press Ctrl + O to save the current document.

Another example: M-U means: press Alt + U to undo the last command.

The Ctrl + Enter key activates the links contained within the documents opened in Nano.

Here is the “main menu” in English:

The wider the terminal window, the more commands are displayed.

The basics are therefore extremely simple to manage, and the learning curve takes just a few minutes.

All you need to do is follow the instructions.

So just launch the editor and read the menu at the bottom of the page.

That's it!

So that's “why Nano.”

2. Pasting from the clipboard

A minor issue occurred when I attempted to paste a text fragment copied to the clipboard into Nano.

The ^U command, indicated in the menu, did not function.

This minor problem stems from the fact that Nano's ^U (Uncut) command searches for text that has been cut within Nano itself using ^K.

The system clipboard, on the other hand, has not been cut within Nano but is the one used with Ctrl+C and Ctrl+V (or right mouse button + copy).

To solve this, use the Terminal shortcut: since Nano runs inside a terminal emulator, you need to use the terminal shortcuts, which usually add Shift to Ctrl + V: so type Ctrl + Shift + V.

Problem solved!

3. Moving between lines

Moving between lines is done very simply using the arrow keys ↑ ↓ ← →.

Alternatively, and this is particularly useful for those familiar with Emacs, you can use the following combinations:

  • Ctrl + P (P is for Previous) moves to the previous line
  • Ctrl + N (N is for Next) to move to the next line.

These are exactly the standard commands of the “old” Emacs, which I am using right now to write this article in Ord Mode.

4. Plugins or no plugins?

The Nano editor does not support extensions or plugins, unlike Vim (with its vast ecosystem of plugins via vim-plug or similar) or other advanced editors.

Nano is designed to be lightweight and simple, focusing on minimal configurations rather than an extensible plugin system.

Therefore, Nano only offers these basic options, which are suitable for quick edits but not for advanced workflows.

5. Setting as the default editor

To set Nano as the default editor in Linux, you need to use an environment variable called $EDITOR.

To make a temporary configuration, type the command export EDITOR=‘/usr/bin/nano’ in the terminal.

In this case, the configuration will only be active until the terminal is closed.

To make the configuration permanent, you need to edit the .bashrc file, perhaps using Nano itself with the command nano ~/.bashrc and adding the following line at the bottom: export EDITOR=‘usr/bin/nano’.

To save, press Ctrl+O, and then Ctrl+X to exit.

To apply the change immediately without restarting: source ~/.bashrc.

For Debian-based distributions, you can also use the command sudo update-alternatives --config editor.

Of course, the process also applies to other editors.

6. Why NOT Nano?

So, Nano is great for quick configurations but has some limitations compared to other more complete, but also more demanding, editors.

In particular, it does not have a built-in “Copy to System Clipboard” key like modern editors.

Furthermore, it cannot be extended with plugins or various extensions.

Vim does everything Nano does and much more.

The problem with Vim is that, unlike Nano, you need to know how to use it, and the learning curve is quite steep.

I would like to point out that, as described in one of my articles, Vim does not necessarily refer to the Vim application, but also to the various emulation modes illustrated in my article.

Thank you for your attention.

To transfer files from one folder to another folder we usually use “copy and paste.” The “universal method” is “copy and paste”: we all know how it works and it is certainly simple and straightforward. But is it also the most efficient method? If there were some documents already previously transferred and others to be transferred, it would be necessary to manually select those to be transferred before doing the “copy and paste,” and this operation could be particularly time-consuming. In cases like these, more efficient solutions should be sought. These solutions exist but are somewhat hidden...

Vim: searching for text containing a slash or a question mark

Vim: searching for text containing a slash or a question mark Vim: the search command To activate a text search in Vim, press one of the following trigger keys in your keyboard: the slash "/" key (do not confuse with the back-slash "\" key) the question mark key. By pressing the slash "/" key will activate a forward search. By pressing the question mark "/" key will activate a backward search. To move the cursor to the results in your document, press the "n" key (mnemonic for “ next ”). To invert the direction of the cursor, press the "N" key, (“upper n”) . What about if you need to search for a slash or a question mark , i.e. the same trigger characters , in your document? You can prepend the Escape character to the trigger key. The Escape character The Escape character is the back-slash key: "\" . Just an example: if you need to forward search (then with / trigger k...
