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!
