When I first learned about Linux in the 90’s, I read that it was possible to even write your own commands to use at the command line. Later I learned about bash scripting, and it wasn’t long before I needed to learn how to loop in bash. Looping in bash is one of the fundamental building blocks of bash programming. It isn’t hard to do at all and is worth learning. The main reason to learn looping in bash is to handle doing the same thing over and over again. They’re easy to do even at the command line. Please follow along as we look a couple of basic examples, and how you can expand on them.

The backwards words are an Algol 68 legacy, and are close brackets that match the correcponding forward-spelled words. The variety of brackets makes it easy to detect, diagnose, and correct missing brackets. I contrast this with C's '}', Pascal's ubiquitous 'END' and Lisp's even more irritating ')'.
