To create the service file with the specified content, you can follow these steps:
1. Open a terminal.
2. Run the following command to open the file in a text editor:
sudo nano /etc/systemd/system/subspace.service
This will open the file `/etc/systemd/system/subspace.service` in the Nano text editor. If the file already exists, it will open the existing file for editing.
3. Copy and paste the following content into the file:
[Unit]
Description=Subspace Node
After=network-online.target
[Service]
User=<your_username>
ExecStart=$(which subspace-cli) farm
RestartSec=10
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
4. Replace `<your_username>` with your actual username. You can find your username by running the `whoami` command in the terminal.
5. Press Ctrl+O to save the file, and then press Ctrl+X to exit the text editor.
The service file `/etc/systemd/system/subspace.service` is now created with the specified content.
