hide password of other info via shell script

[eric stewart]

I have a shell script the prompts the user for some information via the read command that I do not want to be displayed. The terminal type is vt200.
Is there a string that can be written to the terminal to turn display off and another to be turn the display back on?
It would be like echo off and echo on?
TIA

echo off and echo on is going to do the job.

You want something like:

echo "Enter password:"
stty -echo
read PASSWORD
stty echo

Thanks Alan works great

Hi,

just an additional feature to Alans reply:
Within the script add the line:
trap "stty echo" 2 3 15
This ensures that if a user interrupts the script or get a termination signal at the read statement it will turn on echo back.

Cheers
