Capture an empty key press...
I am trying to test input from the user, if they press enter with out an Y or N. I have the characheter thing sorted but when it comes to a blank or empty key press I am having trouble.
if [ ${continue} = '' ]; then
clear
echo "Sorry, that is an invalid choice!"
exit
fi
I am using a KSH script in Solaris.
Thanks in advance.

exmouse
exmouse(3alleg4) Allegro manual exmouse(3alleg4) NAME
exmouse - Getting input from the mouse. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example exmouse DESCRIPTION
This program demonstrates how to get mouse input. The first part of the test retrieves the raw mouse input data and displays it on the screen without using any mouse cursor. When you press a key the standard arrow-like mouse cursor appears. You are not restricted to this shape, and a second key press modifies the cursor to be several concentric colored circles. They are not joined together, so you can still see bits of what's behind when you move the cursor over the printed text message. SEE ALSO
