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:
echo -e '\E
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. Whenever the user enters anything else it just erases the answer and waits for the next one. However, the... (23 Replies)

TPUT(1) BSD General Commands Manual TPUT(1)NAME
tput, clear -- terminal capability interface
SYNOPSIS
tput [-T term] attribute [attribute-args] ...
DESCRIPTION
tput makes terminal-dependent information available to users or shell applications. The options are as follows:
-T The terminal name as specified in the terminfo(5) database, for example, ``vt100'' or ``xterm''. If not specified, tput retrieves
the ``TERM'' variable from the environment.
tput outputs a string if the attribute is of type string; a number if it is of type integer. Otherwise, tput exits 0 if the terminal has the
capability and 1 if it does not, without further action.
If the attribute is of type string, and takes arguments (e.g. cursor movement, the terminfo ``cup'' sequence) the arguments are taken from
the command line immediately following the attribute.
The following special attributes are available:
clear Clear the screen (the terminfo(5) ``cl'' sequence).
init Initialize the terminal (the terminfo(5) ``is2'' sequence).
longname Print the descriptive name of the user's terminal type.
reset Reset the terminal (the terminfo(5) ``rs1, rs2, rs3'' and ``rf'' sequence).
EXIT STATUS
The exit status of tput is based on the last attribute specified. If the attribute is of type string or of type integer, tput exits 0 if the
attribute is defined for this terminal type and 1 if it is not. If the attribute is of type boolean, tput exits 0 if the terminal has this
attribute, and 1 if it does not. tput exits 2 if any error occurred.
EXAMPLES
tput cl cm 5 10 clear the screen and goto line 5 column 10
tput cm 6 11 DC 6 goto line 6 column 11 and delete 6 characters
SEE ALSO termcap(3), termcap(5)HISTORY
The tput command appears in 4.4BSD.
BUGS
tput can't really distinguish between different types of attributes.
Not all terminfo entries contain the reset sequence, so using the init sequence may be more useful.
