PowerShell Version 3 if..else bug

Consider the following from PowerShell’s excellent help: Get-Help about_If 001002003004005006007008 if ($a -gt 2) {    Write-Host “The value $a is greater than 2.”}else{    Write-Host “The value $a is less than or equal to 2, is not created or is not initialized.” } If you modify that example to tighten it up a bit, and make it look better you can cause the […]


Quick modification of the Compare-Command.ps1 script

I found a few issues with my Compare-Command script, and have resolved them. If you have already downloaded it from TechNet, thanks, and you can just modify the following two lines: Line 72 becomes:$V3Detailed |select -ExpandProperty Parameters |ForEach-Object -Process {$V3Paramaters += (“$($_.Name)=$($$($V3ModuleName[0])“)} Line 82, likewise, becomes:$V2Detailed |select -ExpandProperty Parameters |ForEach-Object -Process {$V2Paramaters += (“$($_.Name)=$($_.ParameterType.Split(“.”)[-1])=$($V2ModuleName[0]))”)} While […]

Quickly compare PowerShell V2 and V3 cmdlets

Recently, I was looking for the difference between the Get-ChildItem cmdlet in Version 2 and Version 3 of Windows PowerShell. Although you can Bing “PowerShell Get-ChildItem v3” and get an accurate listing of the new parameters from TechNet, that’s not true for all cmdlets, so I wrote a quick little script to find the information.

Got-Bug? Connect it!

I have been running the various versions of PowerShell 3 since the first Windows 8 developer preview was released, and started using the PowerShell ISE at the same time, as PowerGUI was not compatible with the required .Net 4.0 bits. (That’s since been fixed, and yet I remain with PowerShell ISE). Anyhow, I noticed a […]

PowerShell V3 Console improvement

This may not seem earth shattering, but it’s major news in my world (I’m a 1 finger typist) In the V3 CTP, you now have the ability to use autocomplete in the console, in the middle of a line without losing the rest of the line. This allows you to do this: Get-Mailbox |Select-Object Name, […]


PowerShell V.Next: Simplified Where-Object and ForEach-Object

I was perusing the samples that come with the PowerShell V3  CTP (Samples\WindowsPowerShell) when I noticed a folder called “Simplified Foreach and Where” Lo and behold, you no longer need curly braces “{}” or the $_ to refer to the current object in the ForEach-Object and  Where-Object cmdlets! The sample is incredibly simple, but quickly […]


PowerShell V 3.0 CTP Export-Csv now has an Append parameter!

Great news for all those folks who rely on Export-Csv and who have been wanting an Append parameter! The latest CTP of PowerShell 3.0 now provides the parameter. It’s not perfect, but it’s close – if the data you are exporting does not match the current data, you will receive an error: If you rerun […]


Windows 8 / PowerShell 3.0 / Microsoft Exchange 2010

This is based on the developer’s preview of Windows 8. I will use the tag “Windows 8 Developer Build” for all of these posts. So, I’m playing with Windows 8 and PowerShell version 3, like nearly everyone else on the planet, and decided to install the Exchange Management Tools. The first thing to do is […]
