Exit-Sims.ps1

<#
.Synopsis
    Query if a specified computer has SIMS.net running.
.Description
    Force close any instance of the SIMS process running on a target computer.
    This will drop any work currently open. Intended for use when users have left
    the console open and gone home. This prevents SIMS updates. 
.NOTES
    Caveats;
    1. Can't remote onto computers you are logged onto already
    2. Warning Messages for each computer that hasn't worked. 
        Will continue through the whole list regardless
.EXAMPLE
    Exit-SIMS -ComputerName tech-03,tech-01
    @{computerName=tech-03}
    Have SIMS running. Use -Exit to close these
.EXAMPLE
    Exit-SIMS -ComputerName tech-03,localhost,tech-01 -Exit
#>
function Exit-SIMS{
    Param(
        [string[]]$ComputerName = 'localhost'
    
        , # Close the remote instance of SIMS
        [switch]$Exit
    )

    $ScriptBlock = { Get-Process -name "Pulsar" -ErrorAction SilentlyContinue | Stop-Process -Force }

    switch ($Exit)
    {
        $true
        {
            Invoke-Command $ComputerName -ScriptBlock $ScriptBlock -ErrorAction Continue
        }
        $false
        {
            [string[]]$names = Get-Process -name 'Pulsar' -ComputerName $ComputerName -ErrorAction Continue | 
                Select @{name='computerName'; expression={$_.MachineName} }

            if($names)
            {
                $names
                Write-Output "Have SIMS running. Use -Exit to close these"
            }
        }
    }
