display changing variable in one place on screen in ksh
Is it possible using just korn shell script to display a variable on the screen that is constantly changing in on place on the screen, to tell it in coordinates or something? In a loop, echo will print a new line each time, can I make it a static position? Thanks

In a console, yes. Use ANSI escape sequences to move the cursor. The terminal has to emaulate vt102 or a similar terminal type.

ASCII Table - ANSI Escape sequences

Edit: use the printf statement to create escape sequences.

The terminal emulation is ANSI for telnet sessions (which is what I use), and IBM3151 for real terminal sessions. I am assuming since they are called ANSI escape sequences that it should work for a telnet session? I looked at man printf and did not find any mention of ascii in it. Sorry for being such a noob, but could you give an example command?

I have managed to figure out changing colors with ansi escape sequences:

printf "\033[32m`date`\033[0m\n"

will print the date and time in green. now I know that my emulation supports this, just now need to know how to position the text. Thanks

I found this

Bash Prompt HOWTO: ANSI Escape Sequences: Colours and Cursor Movement

to be quite useful. Thanks for the tip on ANSI escape sequences Smilie

Don't suppose you can somehow do this in WYSE60 emulation? I just tried it and it just printed the escape sequences on the screen...

The WYSE60 requires a different set of escape sequences. Look in the termcap or terminfo database entries to find the correct escape sequences.
