Changing an AIX password via script?

Question

I am trying to change a password of a user via script. I cannot use sudo as there is a feature that requires the user to change the password again if another user changes th

This is from : Script to change password on linux servers over ssh

The script below will need to be saved as a file (eg ./passwdWrapper) and made executable (chmod u+x ./passwdWrapper)

#!/usr/bin/expect -f
#wrapper to make passwd(1) be non-interactive
#username is passed as 1st arg, passwd as 2nd

set username [lindex $argv 0]
set password [lindex $argv 1]
set serverid [lindex $argv 2]
set newpassword [lindex $argv 3]

spawn ssh $serverid passwd
expect "assword:"
send "$password\r"
expect "UNIX password:"
send "$password\r"
expect "password:"
send "$newpassword\r"
expect "password:"
send "$newpassword\r"
expect eof

Then you can run ./passwdWrapper $user $password $server $newpassword which will actually change the password.

Note: This requires that you install expect on the machine from which you will be running the command. (sudo apt-get install expect) The script works on CentOS 5/6 and Ubuntu 14.04, but if the prompts in passwd change, you may have to tweak the expect lines.
