shell script expert

I have below script which will basically run various commands that i enter inside the quotes.

This needs to execute now as "root" user , currently it run as "bob" user which has "root" privilages by becoming root user with sudo su

Please let me know if you can make it without changing below code much.

#!/bin/bash

tmpdir=${TMPDIR:-/home/cloud-user}/output.$$

mkdir -p $tmpdir

count=0

while IFS= read -r host; do

ssh -n -o BatchMode=yes -q -o "StrictHostKeyChecking no" -i /home/cloud-user/keys/[login to view URL] ${host} 'hostname -f & command1 & command2' > ${tmpdir}/${host} 2>&1 &

count=`expr $count + 1`

done < '/home/cloud-user/servers/[login to view URL]'

while [ $count -gt 0 ]; do

wait $pids

count=`expr $count - 1`

done

echo "Output for hosts are in $tmpdir"

exit 0

NOTE:

on all hosts "bob" user exist and he can become root on all hosts without password

Script need to execute on 500 nodes all at once

All commands which are in quotes needs to be executed as "root" user. ('hostname -f & command1 & command2' )

on local host, it currently runs as my id "bob"
