By definition, echo appends a <newline> character to its input arguments in the output it produces. Try using printf instead of echo:
Some non-standard implementations of echo provide an option to avoid printing the terminating <newline>, but printf as shown above should work portably no matter what operating system or shell you're using.
Note that showing us your actual code instead of pseudo-code and telling us what operating system and shell you're using is always much clearer than trying to guess at how pseudo-code might relate to actual code.
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 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.

But I don't get a value or anything. Please help. (3 Replies)

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)
