Hi all... I-m quite a new user of UNIX and i was trying to write a simple program and my problem is the following:how can i make a typed letter disappear (as we see in the MORE command, when we type <space>, b, q etc...) i know that for typing some text that has to be read it's used the structure:
echo "Text"
read ANSWER
but then i can't delete the typed text, or at least i don't know how to do it... 
any help?
Thank u in advance...
