WMII have heard some discussions recently regarding whether Win32_LogicalDisk or Win32_Volume should be used in the answer to event 3 in the Scripting Games.
The problem requires you pull the drive letter, drive size and freespace for local disks on the server. Notice the emphasis – that will be...

PowerShell,
Scripting GamesOne of the principles of writing scripts (or any code) is the KISS principle – Keep It Simple Scripter.
That principle is being abused al lot in event 3
I am seeing numerous entries that define an advanced function as the solution and then inside the PROCESS block define one or more...

WMIIn event 3 you have to get information on hard disk capacity. I’ve only looked at the first couple of dozen scripts but seen this too many times
Get-WmiObject -Class Win32_LogicalDisk | where DriveType -eq 3
or if you prefer the version 2 way
Get-WmiObject -Class Win32_LogicalDisk |...

PowerShell,

$ErrorPref = $ErrorActionPreference
$ErrorActionPreference = "Stop"

$Properties = @{}
$Properties['Computer'] = $SystemInfo.__SERVER
$Properties['OperatingSystem'] = "$($OSInfo.Caption) - $($OSInfo.CSDVersion)"
$Properties['PhysicalMemory'] = $SystemInfo.TotalPhysicalMemory
My immediate thought was the entrant...

WMIThere are some good features to this script but what really hurts is the two trips to the server for the Win32_Computersystem class
Foreach ($IP in (Get-Content "C:\IPList.txt"))
{
$Name = (Get-WMIObject Win32_ComputerSystem -ComputerName $ip).Name
$Mem = [math]::truncate((Get-WMIObject...

WMII haven’t finished blogging about event 1 yet but this caught my eye.
Things aren’t too bad until we hit the bunch of write-host calls
$wrks = (Get-Content -path C:\IPList.txt)
foreach ($wrk in $wrks)
{
$osver = Get-WMIObject -class win32_operatingsystem -ComputerName $wrk

PowerShell,
Scripting GamesThe object of the exercise in both the beginners and advanced sections of event 1 was to move a set of log files older than a give data to an archive folder.
A number of solutions were presented that used robocopy.
This is a workable solution that meets the lettter of the objective but it...

PowerShell,
Scripting GamesI’ve already blogged about incorrect use of backticks. Here is another example of un-necessary use of backticks
$Files= Get-ChildItem `
