IMHO the distinction between command's output (to stdout and stderr) and its return code is one of the faults in UNIX shells. Nothing, but log should be written to stdout by command, and stderr should be useless if we use exceptions (I'm not quite sure).

You have failed to grasp the problem domain and the composability provided. Requiring names for output is worse than requiring names for functions. -- Aaron Denney -><-
