WriteFile writes data to a file named by filename. If the file does not exist, WriteFile creates it with permissions perm; otherwise WriteFile truncates it before writing.

Go

package main

import (
	"io/ioutil"
	"log"
)

func main() {
	message := []byte("Hello, Gophers!")
	err := ioutil.WriteFile("testdata/hello", message, 0644)
	if err != nil {
		log.Fatal(err)
	}
}
