How to get pid from identical running processes and pipe the output into if statement-CodePudding

I want the script to find two identical processes that are currently running and pipe the PID of the process that matches a defined path in the variable $procName by using the If($_.Path -eq $procName){ command.

After the correct process has been identified based on it's full file path found earlier, I want to use it's unique PID to check whether it is currently suspended or not suspended.

If all goes well in the current pipe then use it's output value to run one of two commands below:

If($_.Path -eq $procName) {
    Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner $myPID"
} Else {
    Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner -r $myPID"
}

My issue is the output is the same result no matter if the processes is currently suspended or not Start-Process cmd.exe -WindowStyle Maximized -ArgumentList /D /K pssuspend.exe -nobanner -r 18960

This is what I have so far:

$procName = 'C:\Program Files (x86)\Steam\steamapps\common\rocketleague\Binaries\Win64\RocketLeague.exe'
$procID = Get-Process -Name 'RocketLeague' | Select-Object -Property Id,Path | ForEach-Object {
    If($_.Path -eq $procName){
        $myPID = $_.Id
        If(Get-ChildItem | Where-Object -FilterScript {$_.Responding -eq $false}) {
            Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner $myPID"
            } Else {
            Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner -r $myPID"
        }
    }
}

CodePudding user response：

Based on the code and respecting what Santiago has already pointed out, it looks like you are trying to take certain actions based on whether a particular process is responding. If I have that right, I don't see the need for Get-ChildItem. You could append the Select-Object command to include the Responding property then do the logic like:

$procName = 'C:\Program Files (x86)\Steam\steamapps\common\rocketleague\Binaries\Win64\RocketLeague.exe'

$procID = 
Get-Process -Name 'RocketLeague' | 
Select-Object -Property Id, Path, Responding |
ForEach-Object {
    If($_.Path -eq $procName){
        $myPID = $_.Id
        If( !$_.Responding ) {        
            Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner $myPID"
            } 
        Else {
            Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner -r $myPID"
        }
    }
}

However, and unless there's more to the script, I don't think you need the Select-Object command at all:

$procName = 'C:\Program Files (x86)\Steam\steamapps\common\rocketleague\Binaries\Win64\RocketLeague.exe'

$procID = 
Get-Process -Name 'RocketLeague' | 
ForEach-Object {
    If($_.Path -eq $procName){
        $myPID = $_.Id
        If( !$_.Responding ) {        
            Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner $myPID"
            } 
        Else {
            Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner -r $myPID"
        }
    }
}

Also, nothing will be in the $procID variable as the subsequent code doesn't write anything to the pipeline. I left it in only because I don't know the full intent.

You could also shorten the code Somewhat by moving some of the If Logic into a Where-Object clause, See below with $ProcID removed.

$procName = 'C:\Program Files (x86)\Steam\steamapps\common\rocketleague\Binaries\Win64\RocketLeague.exe'

Get-Process -Name 'RocketLeague' | 
Where-Object{ $_.Path -eq $procName }|
ForEach-Object {    
    If( !$_.Responding ) {        
        Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner $($_.Id)"
        } 
    Else {
        Write-Host Start-Process cmd.exe -WindowStyle Maximized -ArgumentList "/D /K pssuspend.exe -nobanner -r $($_.Id)"
    }
}

Note: I also used string expansion with a subexpression instead of assigning the $myPID variable.
