How do I turn off echo in a terminal?

Question

I\'m writing a Bourne shell script and have a password input like this:

echo -n \'Password: \'
read password

Obviously, I don\'t want the p

Answer 1

You can use '-s' option of read command to hide user input.

echo -n "Password:"
read -s password
if [ $password != "..." ]
then
        exit 1; # exit as password mismatched #
fi

Also you can use 'stty -echo' if you want to hide from terminal to print. And restore the terminal settings using "stty echo"

But I think for getting password input from user 'read -s password' is more than enough.
