Fish: For the Terminal Hipsters
Fish ("Friendly Interactive Shell") appeared in 2005 aiming squarely at new users. It boasts smart autosuggestions, colorful syntax highlighting, and dead-simple scripting.

Terminal windows, printouts, coding style guidelines, even modern IDE defaults—all influenced by that arbitrary 80-column legacy. Why 80 columns? Because ancient punch card machinery was built that way. Modern coding standards owe more to cardboard rectangles than...
