Script to change password on linux servers over ssh

Question

We have a number of Red Hat linux servers in our IT environment. I am being asked by my team members to write a script (preferably shell script) to change a user\'s password

Answer 1

cat /tmp/passwords | ssh $server sudo chpasswd -e

if the password is encrypted, or

cat /tmp/passwords | ssh $server sudo chpasswd

if the password is not encrypted.

/tmp/passwords should have format of "user:password"
