Changing the hostname of your Raspberry Pi can help you easily identify your device on a network, especially when managing multiple Pis. Whether you are setting up a new project or organizing an existing network, this simple guide will show you how to change the hostname of your Raspberry Pi using the command line and the graphical user interface (GUI).
Using the Command Line
The command line is a quick method to change the hostname. Here's how you do it:
-
Open the Terminal: You can access the terminal via the desktop or by pressing
Ctrl+Alt+T

- Restart the Device: For the change to take effect, restart your Raspberry Pi:
sudo reboot
Using the Graphical Interface (Raspberry Pi OS)
If you prefer using the graphical interface, follow these steps:
-
Open the Raspberry Pi Configuration Tool: Go to the main menu, find Preferences, and click on Raspberry Pi Configuration.
-
Change the Hostname: In the System tab, you'll find the Hostname field. Enter your new hostname here.

Changing the hostname of your Raspberry Pi is a straightforward process that can be done within minutes. Whether you choose the command line for its speed and simplicity or the GUI for its user-friendliness, both methods will effectively update your device’s identity on your network.
