In this section, we're going to see how to read the entire contents of a file. We will create a new file called names and I have a bunch of names, for instance, Tarik, Guney, Michael, John, and Montana. We are going to read this file. We're going to use the io utility package that provides a read file function and it accepts the path of the file, that is, names.txt. It returns two things: the actual content of the file and errors. If no error occurs, we're going to convert the contentBytes to a string representation first. Now let's write the content to the console using the following code:
package main
import (
"io/ioutil"
"fmt"
)
func main(){
contentBytes, err := ioutil.ReadFile("names.txt")
if err == nil{ var contentStr string = string(contentBytes)
fmt.Println(contentStr)
}
}On running the code in the terminal by using go run main.go command, you'll obtain the following output:
Thus, you can see that we have read all the names...
