How to do it...

1. Open the console and create the folder chapter01/recipe02.
2. Navigate to the directory.
3. Create the main.go file with the following content:

        package main
        import (
          "fmt"
          "os"
        )

        func main() {

          args := os.Args

          // This call will print
          // all command line arguments.
          fmt.Println(args)

          // The first argument, zero item from slice,
          // is the name of the called binary.
          programName := args[0]
          fmt.Printf("The binary name is: %s \n", programName)

          // The rest of the arguments could be obtained
          // by omitting the first argument.
          otherArgs := args[1:]
          fmt.Println(otherArgs)

          for idx, arg := range otherArgs {
            fmt.Printf("Arg %d = %s \n", idx, arg)

          }
        }

1. Build the binary by executing go build -o test.
2. Execute the command ./test arg1 arg2. (Windows users can run test.exe arg1 arg2).
3. See the output in the Terminal:
