This simple thing to do is take what you do manually and put it in a script.

If you will show us the commands you use to do it, we can help you write the script. If not; you're on your own.

We would expect you to change actual passwords in your code to something like "password" and that you could then figure out how to change that to your real password if we provide a solution for you. (We would also expect you to modify IP addresses, host names, user names, and other personal or private data.)
