Reading the golang official documentation is fun, today I saw the Variables in package os
var Args []string
It allows you to hold command line arguments and a simple main program that can help you validate this.
func main() {
if len(os.Args) > 0 {
fmt.Println(" More than one argument found: " + fmt.Sprintf("%s", os.Args[1:]))
} else {
fmt.Println(" No arguments passed ")
}
}go run main 1 2 3 4#
More than one argument found: [1 2 3 4]Why I used os.Args[1:]#
The argument 0 is the location of the exe itself in my case
