It’s also possible to run the command only once, appending all files as arguments in one go. Use the parallel … Read more
This answers works in Go1: f, err := os.OpenFile(filename, os.O_APPEND|os.O_WRONLY|os.O_CREATE, 0600) if err != nil { panic(err) } defer f.Close() if _, err = f.WriteString(text); err != nil { panic(err) }

Go read The Rust Programming Language‘s chapter on error handling to understand how to appropriately handle failure in your own program. Rust 1.26 and … Read more
