Use the 'expect' program. It works like a charm. You can find it on sunfreeware.com.

It can use the following statements:

Code:
expect assword
send "the actual passwd"

using "assword" makes it portable because some UNIXs use Password instead of password.

Here is a script segment I wrote to change root password via ssh:

Code:
#!/bin/expect -f "$0" ${1+"$@"}
#
# /home/halstead/bin/autopasswd
#
# wrapper to make passwd(1) be non-interactive
# username is passed as 1st argv, passwd as 2nd argv

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