In this program, we will pass arguments at the command line during the execution of the program. Here we will print program-name and arguments on the console screen.
The source code to demonstrate the command-line arguments is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.
// Golang program to demonstrate
// the command-line argument
package main
import "fmt"
import "os"
func main() {
programName := os.Args[0]
arg1 := os.Args[1]
arg2 := os.Args[2]
fmt.Println("Program Name: ", programName)
fmt.Println("Argument1: ", arg1)
fmt.Println("Argument2: ", arg2)
}
Output:
$ go run sample.go "Hello World" 108
Program Name: /tmp/go-build3253235759/b001/exe/sample
Argument1: Hello World
Argument2: 108
Explanation:
In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt, os packages then we can use a function related to the fmt and os package.
In the main() function, we passed arguments at the command line and we printed the program name and other arguments on the console screen.
