How to change the ownership of the file in Golang?

Problem Solution:

In this program, we will change the ownership of the specified file using os.Chown() function. This function works only in the Linux operating system.

Program/Source Code:

The source code to change the ownership of the file in the Linux operating system is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to change the ownership of the file in the Linux operating system

// Golang program to change the ownership of
// the file in the Linux operating system

package main

import "os"
import "fmt"

func main() {
	err := os.Chown("Sample.txt", os.Getuid(), os.Getgid())
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println("File ownership changed successfully")
	}
}

Output:

File ownership changed 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 ownership of the "Sample.txt" file using os.Chown() function. The os.Chown() function will work only in the Linux operating system.
