Change root password using a Bash script

When I order a VPS, I get a random password from them which I need to change.

I basically use CentOS 6 x64.

I was thinking to make a Bash script which when I run will change the password of the VPS to a default common password which I would like to use with all my VPSes.

Is it possible?

I am thinking to use this inside the Bash .sh script. Is my code correct?

#!/bin/bash
passwd
echo jadaruine

If not, what should the code be?

You can do the following to change the password on CentOS

#!/bin/bash
echo "jadaruine" | passwd --stdin user

You want the chpasswd command:

sudo sh -c 'echo username:password | chpasswd'

You might also want to look at chage for password expiry settings.
