Changing Linux password via a script

Problem:

You need to change your Oracle Linux password using a script.

Solution:

As OS user root:

echo -e "My_password\nMy_password" | (passwd --stdin UserName)

As Sudo:

echo -e "My_password\nMy_password" | sudo passwd UserName

Remotely via ssh and sudo:

echo -e "My_password\nMy_password" | ssh HostName -tt  "sudo passwd --stdin UserName"

I hope this helps.
