[Tutor] Displaying Status on the Command Line

[Chip Wachob]

Hello,

I'm sure that this is simple and my searches have just not used the
correct words.

What I would like to do is display, on a single line, in the terminal
/ command line a progress percentage, or, simply a sequence of - / -
\, etc.. or even, accumulating period characters.

What would the escape codes be, or is there a better way to handle this?

Note that I need this to be platform agnostic.

Thank you in advance for your insight.
