Reading the file into a string

In the previous recipes, we saw the reading from Stdin and the opening of the file. In this recipe, we will combine these two a little bit and show how to read the file into a string.

How to do it...

1. Open the console and create the folder chapter05/recipe04.
2. Navigate to the directory.
3. Create the directory temp and create the file file.txt in it.
4. Edit the file.txt file and write multiple lines into the file.

5. Create the readfile.go file with the following content:

        package main

        import "os"
        import "bufio"

        import "bytes"
        import "fmt"
        import "io/ioutil"

        func main() {

          fmt.Println("### Read as reader ###")
          f, err := os.Open("temp/file.txt")
          if err != nil {
            panic(err)
          }
          defer f.Close()

          // Read the
          // file with reader
          wr := bytes.Buffer{}
          sc := bufio.NewScanner(f)
          for sc.Scan() {
            wr.WriteString...
