This recipe illustrates how file permissions can be changed programmatically.

How to do it...

1. Open the console and create the folder chapter06/recipe06.
2. Navigate to the directory.
3. Create the filechmod.go file with the following content:

        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...
