Top Forums Shell Programming and Scripting Get Rid ^C when pressed Ctrl-C Post 302736109 by jim mcnamara on Monday 26th of November 2012 08:35:49 PM

Rather than me blindly giving you code, try using ansi escape sequences inside the
trap statement. Use them to:

Save the cursor position,
then move it to a safe spot,
read foo,
restore the cursor.

The CSI sequences and some of the SGR sequences in this page are worth playing around with a bit. There is a CSI code to turn off the cursor. Some terminal settings are affected by locale, too. If you are using an Asian locale, you are probably using unicode or another wide charset.
