To install, configure, and use Nano on CentOS 10, follow the steps below:
Step 1: Check If Nano Is Already Installed
It’s worth checking first to see if your CentOS installation includes Nano.
|
nano –version |
|---|
This command will show the Nano version installed, if it is. You’ll get a message saying “command not located” if you don’t have Nano installed.
Step 2: Update the CentOS 10 Package Index
By updating your system, you will get the most recent version of Nano that is available from the repositories.
|
sudo dnf update |
|---|
This will update package metadata and install any pending updates. It prevents compatibility or dependency issues.
Step 3: Install Nano on CentOS 10 Using DNF
Installing Nano using the DNF Package Manager is possible.
|
sudo dnf install nano -y |
|---|
This command installs Nano along with all required dependencies.
Step 4: Verify Nano Installation
Verify that Nano has been installed correctly.
|
nano –version |
|---|
The installation is verified, and Nano is now ready for use.
Step 5: Open a File Using Nano
Nano allows you to open or create files directly.
|
sudo nano filename.txt |
|---|
Nano will open the file for editing if it already exists. Nano creates the file if it does not exist.
Step 6: Understanding Nano Keyboard Shortcuts
Nano has Ctrl shortcuts at the bottom.
Common shortcuts:
- Ctrl + O – Save file
- Ctrl + X – Exit editor
- Ctrl + W – Search text
- Ctrl + K – Cut line
- Ctrl + U – Paste line
These shortcuts make Nano beginner-friendly and eliminate the need to memorize complex commands.
Step 7: Edit Configuration Files Safely

|
sudo nano /etc/ssh/sshd_config |
|---|
You can modify system files in a safe manner by using sudo.
Step 8: Enable Syntax Highlighting (Optional)
Nano provides syntax highlighting in programming and configuration files. Let’s open the Nano configuration file:
|
nano ~/.nanorc |
|---|
Add:
|
include /usr/share/nano/*.nanorc |
|---|
The syntax highlighter makes it easier to read scripts and configuration files.
Step 9: Set Nano as the Default Editor
Nano can be configured as the default text editor on CentOS 10.
|
export EDITOR=nano |
|---|
To make it permanent:
|
echo ‘export EDITOR=nano’ >> ~/.bashrc |
|---|
It ensures that Nano is opened by default when a system task requires a text editor.
Step 10: Using Nano Over SSH on CentOS 10
Nano is compatible with SSH connections.
|
ssh user@server-ip sudo nano file.txt |
|---|
Nano’s lightweight design is ideal for remote server management.
