Stop and then run the process in powershell

Question

I would like to stop / kill a specific process, and then start it again after I do what I need to do.

This is what I already have.

Clear-host
$processes = Get-Process devenv 
$processes.Count
if($processes.Count -gt 1)
{
    $i = 0
    Write-host "There are multiple processes for devenv."
    foreach($process in $processes)
    {
        $i++
        $i.ToString() + '. ' + $process.MainWindowTitle
    }
    $in = Read-host "Give a number of the process to kill: "
    write-host
    write-host "killing and restarting: " + $processes[$in-1].MainWindowTitle
    $processes[$in-1].Kill()
    $processes[$in-1].WaitForExit()
    $processes[$in-1].Start()

}
else
{
    write-host "something else"
}

But first, you need some parameter, which, as I thought, I could get from the process. But I'm not quite sure that I know what to give him.

$processes[$in-1].Start()will not work. You need to capture processinfo when you kill, and run the same application again. You can get binary process information and command line information using the WMI Win32_Process class.

For instance,

Clear-host
$processes = Get-Process notepad 
$processes.Count
if($processes.Count -gt 1)
{
    $i = 0
    Write-host "There are multiple processes for notepad."
    foreach($process in $processes)
    {
        $i++
        $i.ToString() + '. ' + $process.MainWindowTitle
    }
    $in = Read-host "Give a number of the process to kill: "
    write-host
    write-host "killing and restarting: " + $processes[$in-1].MainWindowTitle

    #Get the process details
    $procID = $processes[$in-1].Id
    $cmdline = (Get-WMIObject Win32_Process -Filter "Handle=$procID").CommandLine
    $processes[$in-1].Kill()
    $processes[$in-1].WaitForExit()
}
