Echo at specific screen position ?

Ian McClement_1 — Mon, 29 Jul 2002 07:28:24 GMT

Can someone answer me a fairly simple question.
Is it possible to echo (or other command) to a certain screen position (specify row and column) . So as within loop can keep refreshing the character so as to know how many time the loop has executed.
Could clear the screen then echo, but have other info on screen that cannot be cleared.

Cheers
Ian

Hi Ian

You need to use "tput cup y x" where y is the row position and x is the column position.

ie

integer n=0
while true
do
tput cup 3 20
clear
echo $n
let n=n+1
sleep 3
done

Hi,

You should be looking at something like ncurses:

Hi Ian

Sorry mistake above you need to put the clear statement before the tput statement otherwise it resets the position of the cursor.

Hi,

I agree with Nick that tput is a better choice that ncurses.

Hope this helps. Regards.
