load output to variables directly powershell

Question

I have this script to kill VNC precesses and restart VNC service:

$ip = Read-Host 'Enter hostname or IP'

& tasklist /s $ip /FI "IMAGENAME eq winvnc*"

$procid_1 = Read-Host 'pid 1'
$procid_2 = Read-Host 'pid 2'

& taskkill /s $ip /pid $procid_1
& taskkill /s $ip /pid $procid_2

Stop-Service -InputObject $(Get-Service -Computer $ip -Name "uvnc_service")
Start-Service -InputObject $(Get-Service -Computer $ip -Name "uvnc_service")

This command

& tasklist /s $ip /FI "IMAGENAME eq winvnc*"

gives me this output:

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
winvnc.exe                    3576                            0      2,968 K
winvnc.exe                    4444                            0      5,556 K

And I have to enter PIDs (in this case 3576 and 4444) manually to variables $procid_1 and $procid_2

Is there any way how to pass tasklist output directly to variables?

Thanks in advance for any hints! Josef

Use the Get-Process cmdlet instead of tasklist - Get-Process will output real live .NET objects, so you can grab the Id property directly using dot notation:

$RemoteComputer = Read-Host 'Enter hostname or IP'

Get-Process -Name winvnc -ComputerName $RemoteComputer |ForEach-Object {
    & taskkill /s $ip /pid $_.Id
}
