He probably had at least five or ten in mind. I prefer other methods of extracting this information. Usually 'ps -efly' piped into tools like awk/etc to gather what I want, or on occasion, extracting directly from the /proc filesystem. He did not consider these to be proper alternatives. Since the 'ps -o' flags are only useful in that one command, I just look them up in the (rare) situation where they seem the best alternative. Having been at this for decades, I try to reserve my limited memory capacity for factoids that will pay off, and being able to process columnar data generically at an instant seems more useful than knowing a special way to do it with that one command.
