What are the features of the run and start commands when managing applications or services?

The run and start commands are often used to manage applications or services, but they have different purposes:

• run typically executes an application or process directly in the current terminal or session. This means the process will run in the foreground, and you will see its output directly.

• start is more commonly used to launch an application or service in the background or as a separate process, without blocking the current terminal. In some systems, start may also mean launching a service through a service manager.

For example, in the context of Go:

# Running an application in the current terminal
go run main.go

# Running a compiled application in the background
./app &

Or in systems with systemd:

sudo systemctl start myservice

Thus, run is for immediate execution and debugging, while start is for background execution or service management.
