Writing the file

Writing a file is an essential task for every programmer; Go supports multiple ways on how you can do this. This recipe will show a few of them.

How to do it...

1. Open the console and create the folder chapter06/recipe03.
2. Navigate to the directory.
3. Create the writefile.go file with the following content:

        package main

        import (
          "io"
          "os"
          "strings"
        )

        func main() {

          f, err := os.Create("sample.file")
          if err != nil {
            panic(err)
          }
          defer f.Close()

          _, err = f.WriteString("Go is awesome!\n")
          if err != nil {
            panic(err)
          }

          _, err = io.Copy(f, strings.NewReader("Yeah! Go 
                           is great.\n"))
          if err != nil {
            panic(err)
          }
        }

4. Execute the code by running go run writefile.go in the main Terminal.
5. Check the content of the created sample.file:
