Massive change of password

Hi everyone,

I need to change ‘user’ passkey in all Linux Virtual Machines inside a server cluster. Any aid for creating a script that can change passkey to a user in all the servers?

I’ll be keen to hear good feedback and help.

Thanks
Abella

#!/bin/bash

for i in server1 server2 server3
do
ssh $i 'sed -i -e "s/<oldkey>/<newkey/" <path-to-keyfile>"
done

#HTH ;-)
