I'm surprised you didn't mention math. It's astounding to me how fragile it is to add 2 and 2 in the shell. And forget about floating point numbers. Anytime I need basic math in the shell I reach for 'python -c'

It is often easier to reach for my calculator, calculator app, or the address bar, to do arithmetic, than:

      echo "2 + 2" | bc -l

ksh arithmetic includes floating point. Sadly bash made it to the extinguish step before embracing and extending that far. (Compound variables and getopts are the other big omissions.)
