So I also sometimes need a "commands repeater", but that one isn't very good as it clears the screen and then runs the command to redraw... the result is that the screen will have a really obvious/slow flicker and often just be blank if the command takes any real time to run. I thereby might use that in a pinch as it is a bit faster to type (I would never imagine bothering to make a "script" for this as if you remove all of that argument boilerplate all you did was a while/clear/sleep); but, if I am going to stare at the result for more than a minute or two, I find myself pretty quickly getting frustrated with the result and adding the extra few characters to first store the result of the command into a string and then doing the clear followed by an echo of the string to the screen (after which you go back into the sleep).
