2. How to Use Nano Text Editor
In this part, we’ll dive into the usage of Nano text editor. We will cover:
- How to open and close files.
- Text editing tips and tricks.
- Searching and replacing text.
- Basic commands.
Opening and Closing the Nano Editor
The main command to open the editor is:
Instead of the filename value, you can enter any desired value. Keep in mind that if you want to edit an existing file, you must be in the directory where the file is located. Alternatively, you can specify the full path to the file.
For example, to open a file in the current working directory:
It will open a new text editor window and if you make any changes, they will be saved under the same file name. To open a file in another directory use:
Nano will create a new file with the given name if it is not present in the specified directory. If no name has been specified, it will create an empty untitled file and will ask for a name when exiting the editor.
After running the command, you will be taken to the editor window where you can now freely edit the file with the Nano text editor. Use arrow keys on your keyboard to move the cursor around the text.
At the bottom of this window, you can find some shortcuts to use with the Nano editor. Symbol ^ means that you must press CTRL + [Key] (CMD + [Key] for Mac users) to use the chosen command.
To save the changes made in the file and continue editing press CTRL + O.
To exit from the editor press CTRL + X. If any changes have been made to the currently open file, it will ask whether to save them or not otherwise it will exit right away. Input y for yes, or n for no, and then press ENTER.
BONUS TIP: whenever you are opening an important configuration file, use the -w option. By default, nano wraps the file text to fit the display. This may break some configuration files and may cause problems. For example when opening a config file use:
sudo nano -w /etc/apache2/apache2.conf
In order to select text go to the beginning of the text and press ALT + A. This will set a mark for selecting, then move over the text to be selected with the arrow keys.
To copy the selected text press ALT + 6. This will copy text to the clipboard. To cut text press CTRL + K.
If you want to paste text press CTRL + U. If no text is selected before copying or pasting, it will copy/cut the entire line.
Searching / Replacing Text
To search in the text press CTRL + W. It will ask you for the text to be searched. Insert your value and press ENTER. To continue searching for the same text string, ALT + W.
If your goal is to find and replace text, press CTRL+W and then CTRL+R. It will ask for the search text and the text to be replaced by. Afterward, the editor will take you to the first instance of the text and ask you whether to replace it or all of the occurrences.
