HIDING ECHO


If you dont want to display what you type
on the screen, then use the command below:

% stty -echo

This will not echo back the character you
type on the terminal.

To echo back the character you typed:
% stty echo

You can use stty -echo while reading
password from user using scripts,
so that the password wont be echoed
on the screen.
