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.
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 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)

Description
The routine inserts the character into the default window at the current cursor position and the window cursor is advanced. The character
is of the type which is defined in the header file, as containing both data and attributes.
The routine inserts the character into the specified window at the current cursor position. The cursor position is advanced.
The routine moves the cursor to the specified (y, x) position and inserts the character into the default window. The cursor position is
advanced after the character has been inserted.
The routine moves the cursor to the specified (y, x) position and inserts the character into the specified window. The cursor position is
advanced after the character has been inserted.
All these routines are similar to The following information applies to all the routines.
If the cursor moves on to the right margin, an automatic newline is performed. If is enabled, and a character is added to the bottom right
corner of the screen, the scrolling region will be scrolled up one line. If scrolling is not allowed, ERR will be returned.
If is a tab, newline, or backspace, the cursor will be moved appropriately within the window. If is a newline, the routine is called
before the cursor is moved to the beginning of the next line. If newline mapping is off, the cursor will be moved to the next line, but
the x coordinate will be unchanged. If is a tab the cursor is moved to the next tab position within the window. If is another control
character, it will be drawn in the ^X notation. Calling the routine after adding a control character returns the representation of the
control character, not the control character.
Video attributes can be combined with a character by or-ing them into the parameter. This will result in these attributes being set. The
intent here is that text, including attributes, can be copied from one place to another using and For further information, see
The and routines are macros.
Return Values
The and functions return OK on success and ERR on error.
