How to output the required line from the file?

Question

go

There is a txt file, and the line number in the file is also known. How to output a string by its number?

Answer 1

Are you lazy to google?

configFile, err := ioutil.ReadFile("./config")

  if err != nil {
      log.Fatal(err)
  }

  configLines := strings.Split(string(configFile), "\n")

Then from configLines display the required line by its number.
