# Nano - Text Editor
When working on the command line, quite often you will need to create or edit text files. Two of the most powerful and popular command-line editors are Vim and Emacs. Both of them have a steep learning curve that can be intimidating to new users. For those who need a simple editor, there is nano.
GNU nano is an easy to use command line text editor for Unix and Linux operating systems. It includes all the basic functionality you’d expect from a regular text editor, like syntax highlighting, multiple buffers, search and replace with regular expression support, spellchecking, UTF-8 encoding, and more.
In this guide, explain the basic usage of the nano editor, including how to create and open a file, edit a file, save a file, search and replace text, cut and paste text, and more.
### Installing Nano
Nano text editor is pre-installed on macOS and most Linux distros. To check if it is installed on your system type:
```
nano --versionCopy
```
The output will look something like this:
```
GNU nano, version 2.9.3

Copy
```
If you don’t have nano installed on your system, you can install it using the package manager of your distribution.
#### Install Nano on Ubuntu and Debian
```
sudo apt install nanoCopy
```
#### Install Nano on CentOS and Fedora
```
sudo yum install nanoCopy
```
### Opening and Creating Files
To open an existing file or to create a new file, type `nano` followed by the file name:
```
nano filenameCopy
```
Searching and replacing
To search for a text, press `Ctrl+w`, type in the search term, and press `Enter`. The cursor will move to the first match. To move to the next match, press `Alt+w`.
If you want to search and replace, press `Ctrl+\`. Enter the search term and the text to be replaced with. The editor will move to the first match and ask you whether to replace it. After hitting `Y` or `N` it will move to the next match. Pressing `A` will replace all matches.
#### Copping, cutting, and pasting
To select text, move the cursor to the beginning of the text and press `Alt+a`. This will set a selection mark. Move the cursor to the end of the text you want to select using the arrow keys. The selected text will be highlighted. If you want to cancel the selection press `Ctrl+6`
Copy the selected text to the clipboard using the `Alt+6` command. `Ctrl+k` will cut the selected text.
If you want to cut whole lines, simply move the cursor to the line and press `Ctrl+k`. You can cut multiple lines by hitting `Ctrl+k` several times.
To paste the text move the cursor to where you want to put the text and press `Ctrl+u`.
### Saving and Exiting
To save the changes you’ve made to the file, press `Ctrl+o`. If the file doesn’t already exist, it will be created once you save it.
To exit nano press `Ctrl+x`. If there are unsaved changes, you’ll be asked whether you want to save the changes.
This opens a new editor window, and you can start editing the file.
