Far from it. Welcome to the ambiguity of email.

Ah, I see. In the English language, "output" is all one word.

Coordinates for what, or where? All tput does is query the terminfo

That depends on your distribution.

Again, can be achieved via tput (you've been shown examples of this.)

You seem to be under the impression that your script is somehow lacking
and isn't working. That's not true. Your script does work -- for some
terminals. When you sent this script in to TAG, did think it was somehow
not open for discussion? Constructive criticism such as the advice myself
and Ben have been giving you is there to aid you; and not to pick any
holes in your script.

No, it's the terminal that interprets them. Note from console_codes(4):
It is generally not good practice to hard-wire terminal controls
into programs. Linux supports a terminfo(5) database of terminal
capabili- ties. Rather than emitting console escape sequences by hand,
you will almost always want to use a terminfo-aware screen library or
utility such as ncurses(3), tput(1), or reset(1).
