Check Whether a Path Exists in Golang

Tips & Traps¶

There is no built-in function to check for the existence of a path in Golang. However, you can achieve it using os.Stat + os.IsNotExist.

import "os"

_, err := os.Stat("/some/non-exist/path")

err

stat /some/non-exist/path: no such file or directory

os.IsNotExist(err)

true

The function ExistsPath below is an implementation based the idea abvoe.

func ExistsPath(path string) bool {
	_, err := os.Stat(path)
	if os.IsNotExist(err) {
		return false
	}
	return true
}

ExistsPath("/some/non-exist/path")

false
