Run a command in a list of servers. (Note there are better tools to do this like pssh pdsh, ...)

ForEachServer.sh

#!/bin/bash
#Server list:
declare -a arr=("server1" "server2" "server3")
#Command to execute:
cmd="./cpuuse.sh"

for i in "${arr[@]}"
do
   echo "***Connecting to $i***"
   ssh "$i" "$cmd"
done
