I’m using PM2 to run my Next.js app on a custom port and I want to keep the command generic.

sudo pm2 start npm --name <your-app-name> -- start -- -p <your-port>

• <your-app-name>: the name you want PM2 to use for the process
• <your-port>: the port number your app should listen on

Just replace those two placeholders with your own values.
