Another way might be to use tput cup row column to set the cursor position on the screen, but you have to know what shape screen you have and it's usually better to clear it before you begin so you know that there is nothing to overwrite.
Yet another an alternate could be to just output a dot or other character without the new-line each time round the loop with printf
How much output would you expect, or iterations round your loop? Are you watching a file grow, for instance?
You could:-
This will show the file growing until your script carries on and terminates the watcher.
Does any of these help? it really depends on what you eventually want to do. If you can put it in context, we might refine our suggestions.
I want to get the screen width and cursor positions.
When I used curses, all the screen content was cleared.
So Can I use curses to get the screen size without clearing anything in the window?
Or is there any other alternative???
I can use only C or C++. (0 Replies)

I need to get the cursor position, and put it inside a variable. Problem is, i don't have the tput command, or ncurses.
Apparently I was supposed to try the following:

But I don't get a value or anything. Please help. (3 Replies)
I have a slight problem controlling the cursor position in a Bash terminal window. I have a function ask a question and then wait for an answer which is either 'y' or 'n' or a carriage return.

move
MOVE(7) SQL Commands MOVE(7)NAME
MOVE - position a cursor on a specified row of a table
SYNOPSIS
MOVE [ direction ] [ count ]
{ IN | FROM } cursor
DESCRIPTION
MOVE allows a user to move cursor position a specified number of rows. MOVE works like the FETCH command, but only positions the cursor
and does not return rows.
Refer to FETCH [fetch(7)] for details on syntax and usage.
NOTES
MOVE is a PostgreSQL language extension.
Refer to FETCH [fetch(7)] for a description of valid arguments. Refer to DECLARE [declare(7)] to define a cursor. Refer to BEGIN
[begin(7)], COMMIT [commit(7)], and ROLLBACK [rollback(7)] for further information about transactions.
USAGE
Set up and use a cursor:
BEGIN WORK;
DECLARE liahona CURSOR FOR SELECT * FROM films;
-- Skip first 5 rows:
MOVE FORWARD 5 IN liahona;
MOVE
-- Fetch 6th row in the cursor liahona:
FETCH 1 IN liahona;
FETCH
code | title | did | date_prod | kind | len
-------+--------+-----+-----------+--------+-------
P_303 | 48 Hrs | 103 | 1982-10-22| Action | 01:37
(1 row)
-- close the cursor liahona and commit work:
CLOSE liahona;
COMMIT WORK;
COMPATIBILITY
SQL92
There is no SQL92 MOVE statement. Instead, SQL92 allows one to FETCH rows from an absolute cursor position, implicitly moving the cursor
to the correct position.
