Powershell Arrays - checking to see if services have stopped

Question

I know there is a quicker way of doing this but I just don't know how to approach it. I also need it to work in PowerShell V2 as I still have Windows 2003 servers I need to handle with this.

Basically this would stop services and then check to see if those services were stopped. I have a location to define them earlier in the script. I am using this to deploy code to servers so depending on the code from Development I may need to stop 1 to 4 services and looking to see if there is a way that I can define the services and not have to comment out code below if I only use 2 services as opposed to four.

#Turn off Services
    stop-service $Service1 -force
#   stop-service $Service2 -force
#   stop-service $Service3 -force
#   stop-service $Service4 -force

$VerifyServiceStopped1 = Get-Service $Service1 | Where-Object {$_.status -eq "Stopped"} | select -last 1
#   $VerifyServiceStopped2 = Get-Service $Service2 | Where-Object {$_.status -eq "Stopped"} | select -last 1
#   $VerifyServiceStopped3 = Get-Service $Service3 | Where-Object {$_.status -eq "Stopped"} | select -last 1
#   $VerifyServiceStopped4 = Get-Service $Service4 | Where-Object {$_.status -eq "Stopped"} | select -last 1

    if ($VerifyServiceStopped1) {Write-Host $Service1' Stop = Pass (0)'} else {Write-Host $Service1' Stop = Fail (1000)'; Exit '1000'}
#   if ($VerifyServiceStopped2) {Write-Host $Service2' Stop = Pass (0)'} else {Write-Host $Service2' Stop = Fail (1001)'; Exit '1001'}
#   if ($VerifyServiceStopped3) {Write-Host $Service3' Stop = Pass (0)'} else {Write-Host $Service3' Stop = Fail (1002)'; Exit '1002'}
#   if ($VerifyServiceStopped4) {Write-Host $Service4' Stop = Pass (0)'} else {Write-Host $Service4' Stop = Fail (1003)'; Exit '1003'}

Any suggestions?

Thanks

Answer 1

Something like this, perhaps?

$services = @(
 'Service1',
 'Service2',
 'Service3',
 'Service4')

 Get-service | 
 Where { $Services -Contains $_.Name} |
 Foreach {
  #Stop Service
  #Verify Service
  #Restart Service
  }

I'm not sure how you want to handle this, but since arrays is tagged:

$services = @("ServiceName1","ServiceName2")

#Turn off Services
foreach($service in $services) {
    stop-service $Service1 -force
    $VerifyServiceStopped1 = Get-Service $Service1 | Where-Object {$_.status -eq "Stopped"} | select -last 1
    if ($VerifyServiceStopped1) {
        Write-Host $Service1' Stop = Pass (0)'
    } else {
        Write-Host $Service1' Stop = Fail (1000)'
        Exit '1000'
    }    
}

"so depending on the code from Development I may need to stop 1 to 4 services"

If you cannot define the logic involved in that decision, how do you plan to automate it?

Just wanted to provide the entire code used in case someone else is looking for something similar - thanks to everyone for throwing ideas into the mix it was very helpful.

#Define Services 
     $Service1 = 'servicename'
     $Service2 = 
     $Service3 = 
     $Service4 = 
     $Service5 = 
     $Service6 = 
     $Service7 = 
     $Service8 =
     $Service9 = 

     $services = @(
     $Service1,
     $service2,
     $service3,
     $service4,
     $Service5,
     $Service6,
     $Service7,
     $Service8,
     $Service9)

#Stop Services

     Get-service | 
     Where { $Services -Contains $_.Name} |
     Foreach {

     $_ | stop-service

     } 

     Set-Service |
     Where { $Services -Contains $_.Name} |
     Foreach {

     $_ | -startuptype "Disabled"

     }

#Verify Services

     Get-service | 
     Where { $Services -Contains $_.Name} |
     Foreach {

     if ((Get-Service $_.Name).Status -eq "stopped") {Write-Host 'Service Start Pass (0)'} else {Write-Host 'Start Fail (1000)';Exit '1000'}

     }


#Start Services

     Set-Service |
     Where { $Services -Contains $_.Name} |
     Foreach {

     $_ | -startuptype "Automatic"

     }

     Get-service | 
     Where { $Services -Contains $_.Name} |
     Foreach {

     $_ | start-service

     }


#Verify Services

     Get-service | 
     Where { $Services -Contains $_.Name} |
     Foreach {

     if ((Get-Service $_.Name).Status -eq "running") {Write-Host 'Service Start Pass (0)'} else {Write-Host 'Start Fail (2000)';Exit '2000'}

     }

This allows me to have someone list any services they need to stop / start to deploy custom code out there - also then I will be moving this to stop executables in order to replace them and other files for verification. Sadly we are handed a collection of exe's and dll's to just hot swap for some deployments of software so this is why this was needed. I wanted a way of defining what I need to move in and out per deployment but didn't want to comment out lines throughout the script that I didn't need (i.e. only had two services so needed to comment out the others throughout the script).

Just access the status directly:

> (Get-Service -Name "Windows Time").Status -eq "Stopped"
$true

or

if ((Get-Service -Name "Windows Time").Status -eq "Stopped")
{
    Write-Host "Yep..."
}

or if you want to be really terse, you can use the alias gsv:

> (gsv "Windows Time").Status -eq "Stopped"
$true

You could also make a function:

Function IsStopped ($name)
{
    ((Get-Service $name).Status -eq "Stopped")
}

if (IsStopped "Windows Time")
{
    Write-Host "foo"
}
