func main() {

  f, err := os.Open("inputfile")
12
  if err != nil {
13
    log.Fatal(err)
14
  }
15
  defer f.Close()
16

17
  scanner := bufio.NewScanner(f)
18
  for scanner.Scan() {
19
    fmt.Println(scanner.Text())
20
  }
21
  if err := scanner.Err(); err != nil {
22
    log.Fatal(err)

  }

You could also:

Use ioutil.ReadFile to read the whole file into memory.
Use a buffer with bufio.NewReader to read the file line by line.
