I need a script to change server automatically after performing some operations.
The command for changing server is ssh username@servername . Then a prompt comes to enter a password. Then i need to perform some opertaions on the other server. How can i do this in a script?

#!/bin/bash

ScriptsPath=../Scriptpath/..

for Server in $ServerList
do
 {
  ssh -qt username@$Server $ScriptsPath/ScriptName.sh }
done
