How to check whether a file or directory exists?

I want to check the existence of file ./conf/app.ini in my Go code, but I can't find a good way to do that.

I know there is a method of File in Java: public boolean exists(), which returns true if the file or directory exists.

But how can this be done in Go?

Solution 
  • func exists(path string) (bool, error) {
    _, err := os.Stat(path)
    if err == nil {
        return true, nil
    }
    if errors.Is(err, fs.ErrNotExist) {
        return false, nil
    }
    return false, err
}
