Starting multiple Windows services if stopped - windows

Question

I've tried the following few bits and i'm trying to create a function to insert into another powershell script
function start-OService{
Get-Service service1|?{$_.Status -eq 'Stopped'}|Start-Service
Get-Service service2|?{$_.Status -eq 'Stopped'}|Start-Service
}
And this one ...
function start-OService {
$services = 'service1', 'service1'
Get-Service | ? {
$services -contains $_.Name -and $_.Status -eq 'Stopped'
} | Start-Service
}
The first snippet doesn't seem to run correctly but i'm not getting an error. I can run each line individually but not the way I have it setup.
The 2nd one was my original attempt that was taken from another SO question. The Get-Service doesn't seem to like the $services variable having multiple services contained.

Answer 1

Try this:
function start-OService {
$services = 'service1', 'service1'
foreach ($service in $services)
{
if ((Get-Service $service).Status -eq "Stopped")
{
Start-Service $service
}
}
}

Answer 2

One liner:
"service1", "service2" | Get-Service | ?{ $_.Status -eq "Stopped" } | Start-Service

Answer 3

For starting all the services which was stopped at a given time, below script will be helpful
$StoppedServices=Get-Service | where {$_.Status -eq "Stopped"}
foreach ($item in $StoppedServices)
{
$Name=$item.Name
Start-Service -Name $Name
}

Answer 4

function start-OService {
$services = 'service1', 'service1'
$services | % {
$service = get-service -name $_;
if($service.Status -eq [System.ServiceProcess.ServiceControllerStatus]::Stopped)
{
Write-Output "Starting $_"
$service.Start()
}
}
}
