The Go tool set has several different commands. You can pull up a list of those commands by typing:

package main /*from  www.  ja  v  a 2 s . c o m*/

import "fmt" 

// this is a comment 

func main() { 
    fmt.Println("Hello, World") 
}

Save it as main.go.

Open up a new terminal and type in the following: 

go run main.go
