Regarding more than one mentions of UUOC in this thread: - The original award started in 1995. Even though pentium was already out, I think it is safe to say that was the era of 486 PCs. In 2019, for day-to-day shell work (meaning no GBs of file-processing or anything like that), isn't invoking UUOC and pointing out inefficiencies an example of premature optimization [1]? - Isn't readability a matter of subjectivity, and that for some folks 'cat file' is more readable than '<file' or a direct use of a processing command (like grep, tail, head, etc) [2] ? (The whole stackoverflow page is fairly illuminating [3]).
