Escape from boredom

Needed a script that searches a the entire disk for Java dump files (core, snap, heap, javacore). In addition the files should not be older than X days to limit the search results. Since I have decided that all scripts I create that is related to server maintenance should be written in Powershell I just had to roll up my sleeves and head on to Google to be inspired. Below you can see the result.

param (
    [string]$logFile = $(throw "******************************`n" + 
			"Custom error:`nMissing required parameter -logFile." +
			"`nSpecify name without full path`n******************************`n`n")    
)
### Uncomment line below to enable debug
#$DebugPreference = "Continue"

# The script will search the d-drive by default
# If d does not exist it will search the c drive 
$drive = "d:"
If (!(Test-Path d:))
{
	$drive = "c:"
	If (!(Test-Path c:)) {
		throw "Did not find d or c-drive, script will cannot continue"
	}
}
$fullLogFile = Join-Path "$drive\temp\" "$logFile";
Start-Transcript $fullLogFile;
