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?

Answer 1

This is how I did it:

package main

import (
  "fmt"
  "os"
  "bytes"
  "log"
)

func main() {
   filerc, err := os.Open("filename")
   if err != nil{
     log.Fatal(err)
   }
   defer filerc.Close()

   buf := new(bytes.Buffer)
   buf.ReadFrom(filerc)
   contents := buf.String()

   fmt.Print(contents) 

}
