        package main        import (          "fmt"          "os"        )        func main() {          f, err := os.Create("test.file")          if err != nil {            panic(err)          }          defer f.Close()          // Obtain current permissions          fi, err := f.Stat()          if err != nil {            panic(err)          }          fmt.Printf("File permissions %v\n", fi.Mode())          // Change permissions          err = f.Chmod(0777)          if err != nil {            panic(err)          }          fi, err = f.Stat()          if err != nil {            panic(err)          }          fmt.Printf("File permissions %v\n", fi.Mode())        }

4. Execute the code by running go run filechmod.go in the main Terminal.
