Program/Source Code:

The source code to rename a specified file with a new name is given below. The given program is compiled and executed successfully.

// Golang program to rename a specified file

package main

import "os"
import "fmt"

func main() {
	err := os.Rename("Sample.txt", "NewName.txt")
	if err != nil {
		fmt.Println("File does not exist")
	}
	fmt.Println("File renamed successfully")
}

Output:

File renamed successfully

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 changed the name of a file with a new name using os.Rename() function and printed the "File renamed successfully" message on the console screen.
