How to keep checking the process after every 30 minutes? - windows

Question

I need to kill the process if start time is less than 2 hours.
I need to add sleep for 30 mins if start time is more than 2 hours.
I need to keep repeating it until the process is no more running.
I have written the below script so far to perform the above action.
$procName = 'myprocess'
$process = Get-Process | Where-Object Name -EQ $procName
if(-not $process) {
Write-Warning "$procName not found!"
}
else {
$process | ForEach-Object {
if($_.StartTime -lt [datetime]::Now.AddHours(-2)) {
Stop-Process $_ -Force
}
else {
sleep(1800)
}
}
}
}
How to add the above program in a do-while or another loop so as to keep checking until the process is no more running?
Also, how to implement a maximum timer of 4 hours?

Answer 1

If I understood correctly, your else condition could look like this using a do-while loop:
else {
do {
"$procName is still running, sleeping for 1800 sec"
Start-Sleep -Seconds 1800
} while(Get-Process | Where-Object Name -EQ $procName)
}
However note that this could cause an infinite loop if the process never stops or you implement a maximum timer, etc.
Following your comment regarding implementing a maximum timer, there are many ways you could do it, my personal preference would be to use a StopWatch:
else {
$timer = [System.Diagnostics.Stopwatch]::StartNew()
do {
# Do this while the process is still running AND
# the timer hasn't yet reached 4 hours
"$procName is still running, sleeping for 1800 sec"
Start-Sleep -Seconds 1800
$stillRunning = Get-Process | Where-Object Name -EQ $procName
} while($stillRunning -and $timer.Elapsed.Hours -lt 4)
$timer.Stop()
}

I suggest you use a windows schedule task that launch your powershell script every 30 minutes or so instead of blocking resource with your powershell that is waiting.
You can launch powershell and pass a script.
PowerShell.exe -File "C:\script.ps1"
