I needed a quick and easy way to extract the GUID number from an event log description for a System Center Orchestrator RunBook I was creating for a customer.
$EventID = 'The following "GUID:1234-567-890" is causing problems. Please fix'
$Text = $EventID -split ' '
$GUID = $Text -like '"GUID:*"' -replace '"',''
It's a quick and easy way to extract the text I needed from a string and pass it along.
*note: Those are single quotes around double quotes.
