One shot with the script to achieve multiple targets My target was given to check the status of smartd services in each host and disable it, So I have put the commands on the variable $cmd and $cmd2 and executing it in all the machines,  which has been feed in the variable $machines , command get executed in all the hosts fed in the variable $machines . Script :  $user = '' $pswd = '' $cmd = 'etc/init.d/smartd status' $cmd2 = 'chkconfig smartd off' $machines = Get-Content "" foreach ( $MACHINE in $machines ) { Get-VMHost -Name $MACHINE | % {     $ssh = Get-VMHostService -VMHost $_ | where { $_ .
