When you type your password, Unix turns off echoing so what you type won't show on the screen. You can do the same thing in shell scripts with stty -echo.
stty Section 5.7, read Section 35.18
+#!/bin/sh ... trap 'stty echo; exit' 0 1 2 3 15 # use the right echo for your Unix: echo "Enter code name: \c" #echo -n "Enter code name: " stty -echo read ans stty echo ...
The response is stored in $ans. The trap (Section 35.17) helps to make sure that, if the user presses CTRL-c to abort the script, characters will be echoed again.
