write a shell script to ssh to a remote machine and execute commands

Question

I have two questions:

1. There are multiple remote linux machines, and I need to write a shell script which will execute the same set of commands in each machine.

Answer 1

You can follow this approach :

• Connect to remote machine using Expect Script. If your machine doesn't support expect you can download the same. Writing Expect script is very easy (google to get help on this)
• Put all the action which needs to be performed on remote server in a shell script.
• Invoke remote shell script from expect script once login is successful.
