How to check if a file exists in Go?

Question

Go\'s standard library does not have a function solely intended to check if a file exists or not (like Python\'s os.path.exists). What is the idiomatic way

Answer 1

You should use the os.Stat() and os.IsNotExist() functions as in the following example:

// Exists reports whether the named file or directory exists.
func Exists(name string) bool {
    if _, err := os.Stat(name); err != nil {
        if os.IsNotExist(err) {
            return false
        }
    }
    return true
}
