getting error while running this powershell script.

Question

when i run this powershell script i have to manually feed a parameters!! is there is any way toh automate that step.

this is the script

>

param (
[Parameter(Mandatory=$true)]
[string] $wlidsvc,
[string] $Action,
[string] $ServiceStatus,
)

Checks if wlidsvc exists and provides stop

function CheckMyService ($wlidsvc)
{
if (Get-Service $ wlidsvc -ErrorAction SilentlyContinue)
{

$ServiceStatus =(Get-Service -Name $S wlidsvc).Status

    Write-Host $ wlidsvc "-" $stop
}
else
{
    Write-Host "$ wlidsvc not found"
}

}

Condition if user wants to start a service

elseif ($Action -eq 'Start')
{
    if ((Get-Service -Name $ wlidsvc).Status -eq 'Running')
    {
        Write-Host $ wlidsvc "already running!"
    }
    elseif ((Get-Service -Name $ wlidsvc).Status -eq 'Stopped')
    {
        Write-Host $ wlidsvc "is stopped, preparing to start..."
        Get-Service -Name $ wlidsvc | Start-Service -ErrorAction SilentlyContinue
        CheckMyService $ wlidsvc
    }
    else
    {
        Write-Host $ wlidsvc "-" $start
    }
}

Hi @ANKIT SINGH ,

I played around with the script. Please check if this is working for you. Be aware to start services you need to have administrator privileges on the computer.

CSV file (test2.csv):

 wlidsvc,action  
 AxInstSV,start  
 AppReadiness,start  

Script:

function FuncCheckService {  
    param($wlidsvc,  
        $action  
    )  
    $service = Get-Service -Name $wlidsvc -ErrorAction SilentlyContinue  
    if ($service) {  
        if ((($service).Status -ne "Running" -and ($service).StartType -ne "Disabled") -and ($action -eq "start")) {  
            Start-Service $wlidsvc  
            Write-Host "Starting $wlidsvc service `r`n ---------------------- "   
            Write-Host -ForegroundColor Green " $wlidsvc service is now started"  
        }  
        if ($service.Status -eq "running") {   
            Write-Host "$wlidsvc service is already started" -ForegroundColor Yellow  
        }  
        if ($action -ne "start" -and (($service).Status -ne "running")) {   
            Write-Host "$wlidsvc service does not have action start set" -ForegroundColor Magenta  
        }  
    }  
    else {  
        Write-Host "$wlidsvc service not found" -ForegroundColor Red  
    }  
}  
$lines = Import-Csv -Path C:\Junk\test2.csv -Delimiter ","  
foreach ($line in $lines) {  
    FuncCheckService -wlidsvc $line.wlidsvc -action $line.action  
}

Hi @ANKIT SINGH ,

I am not sure what you exactly mean with "automate the step with providing the parameters".

But one option is maybe to provide the parameters in a CSV file. Maybe this example helps.

Create a CSV file with parameters (test1.csv):

wlidsvc,Action,ServiceStatus  
svc1,restart,running  
svc2,stop,running  
svc3,start,stopped  

Simple script as example:

# Define Function   
function JustForTest {  
    param (  
        [string]$wlidsvc,  
        [string]$Action,  
        [string]$ServiceStatus  
    )  
    # Put your code here  
    Write-Output "wlidsvc = $wlidsvc - Action = $Action - Status  = $ServiceStatus"  
}  
# Read CSV file with parameters  
$lines = Import-Csv -Path C:\Junk\test1.csv -Delimiter ","  
# Execute function for each line in CSV using the parameter values  
foreach ($line in $lines) {  
    JustForTest $line.wlidsvc $line.Action $line.ServiceStatus  
}  

Result will look like this:
