How can I read a whole file into a string variable?

Question

I have lots of small files, I don't want to read them line by line. Is there a function in Go that will read a whole file into a string variable?

Chris Gregori · Accepted Answer

Use ioutil.ReadFile: func ReadFile(filename string) ([]byte, error) You will get a []byte instead of a string. It can be converted if really necessary: s := string(buf) refer below example: package main import ( "fmt" "io/ioutil" ) func main() { b, err := ioutil.ReadFile("file.txt") // just pass the file name if err != nil { fmt.Print(err) } fmt.Println(b) // print the content as 'bytes' str := string(b) // convert content to a 'string' fmt.Println(str) // print the content as a 'string' }
