func CommandError(err error) error

CommandError turns an *exec.ExitError into a gRPC-flavored error using the command's exit code as the gRPC code (if valid) and the command's stderr (or an excerpt from it) as the error message. If the provided error is not an *exec.ExitError then the error is wrapped with a ready-to-display message.
