I was at Bell during the options “debate.” I think something that this otherwise wonderful article misses is that some believed that commands were never intended to be the only way to use the system as the shell was intended to be just one of the many user interfaces that Research Unix would provide. From that perspective, it was entirely reasonable to believe that if a command was so complex that it needed options than it was likely more appropriate for one of the other user interfaces. I believe this is unfortunately now understood by some as it shouldn’t exist. However, because of the seemingly instantaneous popularity of the shell and pipelining text it became synonymous with Unix. It’s a shame because McIlroy had a lot of interesting ideas around pipelining audio and graphics that, as far as I know, never materialized.
