how to redirect STDIN to hp-ux's passwd

I have this script that will auto fill in the password for a new account created in the system:

Code:

echo $PASW1 | passwd --stdin userid

This works in linux, but in hp-ux 11x it wont work. I've already checked the man pages and there is no entry or option on how to replicate the same for the

is it -n? didn't work.

HP-UX passwd command does not allow for stdin because it is an interactive command.

There are some ways to automate this - there is a good discussion here:

Expect is your friend. You can use this code.

Code:

#!/usr/bin/expect
# USAGE : ./script username new_password

spawn passwd [lindex $argv 0]
set password [lindex $argv 1]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof

I see; I will research more into 'expect'. This command/phrase is totally new to me.

thanks!
