Accept input in hidden mode

Hi all,

Perhaps it's a trivial question.

I need to accept a variable from a script and I want this accept in hidden mode.

Is it possible?

Regards, Vicente.

Hi,

Here is a thread that shows how to do it by turning off the echo and also using a trap statement to catch input such as Ctrl-C.
