Powershell停止服务，清理磁盘，然后启动服务

Question

Im trying to write a powershell script to stop services. WAIT for these services to stop and then run disk defrag for 4 disks and then run services again. I tested the below but powershell keep performing step after step while i need powershell to wait until each step is finished to perform the next step.

Stop-Service -Name 'Service1' -Force
Stop-Serivce -Name 'Service2' -Force
Optmize-Volume -DriveLetter C -Defrag
Optmize-Volume -DriveLetter D -Defrag
Optmize-Volume -DriveLetter E -Defrag
Start-Service -Name 'Service1'
Start-Service -Name 'Serivce2'

Thanks in advance.

You can check the status of the service before executing the next command

Stop-Service -Name 'ServiceName' -Force
$serv = Get-service -Name 'ServiceName'
Write-Host $serv.Status
while ($serv.Status -ne "Stopped"){
    Start-Sleep -Seconds 5

}
