hashing out typed passwords

Hi all.

Very new to Bash scripting well infact any scripting. So i hope that
you maybe able to help me out here.


I have a script that asks for a password to be entered so it can be
used later on in the script. This works great execpt tyat you can see
the password in plain text when you have enterd it on screen. What i
would really like it to do is to echo ****** as i type the password.
That way nobody should be able to scroll up the screen buffer to get
the password.


Is it possible? if so how


Cheers
