Golang : Check if a file exist or not

In this tutorial, we will see how to check if a file exist or not before performing further operation.

checkfileexist.go

 package main

 import (
  "fmt"
  "os"
 )

 func main() {
  file := "file.txt"

  if _, err := os.Stat(file); err == nil {
 fmt.Println(file, "exist!")
  }

 }

if the file.txt is there, you should see the output

file.txt exist!
