The growth of command line options, 1979-Present
This table has the number of command line options for various commands for v7 Unix (1979), slackware 3.1 (1996), ubuntu 12 (2015), and ubuntu 17 (2017). Cells are darker and blue-er when they have more options (log scale) and are greyed out if no command was found. We can see that the number of command line options has dramatically increased over time; entries tend to get darker going to the right
