Fedora / Manjaro – Change Hostname – Var 2

To change the computer name in Manjaro Linux, follow these steps:

1. Edit the `/etc/hostname` File

Open a terminal and run the following command to edit the hostname file:
```
sudo nano /etc/hostname
```
Replace the existing name with the new hostname you want.
Save and exit (in nano, press CTRL+O, Enter to save, and CTRL+X to exit).

2. Edit the `/etc/hosts` File

Edit the hosts file to reflect the new hostname:
```
sudo nano /etc/hosts
```
Update the line that contains your old hostname to the new one. It typically looks something like this:
```
127.0.0.1   localhost
127.0.1.1   old-hostname
```
Change old-hostname to your new hostname:
```
127.0.1.1   new-hostname
```
Save and exit.

3. Apply the Changes

To apply the changes, you can either reboot your system:
```
sudo reboot
```
Or, you can run the following command to apply the hostname change without rebooting:
```
sudo hostnamectl set-hostname new-hostname
```

4. Verify the Change

After rebooting or applying the changes, verify the hostname by running:
```
hostname
```

This should change the computer name in your Manjaro Linux system.
