If you are familiar with Powershell scripting, you surely know that variables can really mess up your day.

I’ve written a little function you can dot source into your script and run at specific points in your script to show the current variables and their types and values. It’s not perfect, and I’ll probably make it prettier in time. But here you go.



 Function CheckMyVariables

    Function CheckVariableType

            Write-Host ""
            Write-Host -ForegroundColor DarkGray "*Started*"

            #Check what kind of type the variable is and if it is empty
            If(!($InputData)){Write-Host -ForegroundColor Yellow "The variable $Inputname is Null or Empty ";Return}
            If($InputData -is [String] -eq $true){Write-Host -ForegroundColor Green ""$"$Inputname is a: " -NoNewline;Write-Host "[String]"}
            Elseif ($InputData -is [Int] -eq $true){Write-Host -ForegroundColor Green ""$"$Inputname is an: " -NoNewline;Write-Host "[Int]"}
            Elseif ($InputData -is [Array] -eq $true){Write-Host -ForegroundColor Green ""$"$Inputname is an: " -NoNewline;Write-Host "[Array]"}
            Elseif ($InputData -is [System.Boolean] -eq $true){Write-Host -ForegroundColor Green ""$"$Inputname is an: " -NoNewline;Write-Host "[Boolean]"}
            Elseif ($InputData -is [System.Collections.Arraylist] -eq $true){Write-Host -ForegroundColor Green ""$"$Inputname is an: " -NoNewline;Write-Host "[Arraylist]"}

            #Formatting output of Arrays and Arraylists
            If($InputData -is [Array] -eq $true -or $InputData -is [System.Collections.Arraylist] -eq $true)
                Write-Host -ForegroundColor Green ""$"$Inputname value(s) is/are:"

            #Normal formatting on everything else
                Write-Host -ForegroundColor Green ""$"$Inputname value(s) is/are: " -NoNewline
                Write-Host $InputData

            #If switch is enabled then run the following
            If($Full -eq $true)
                Write-Host -ForegroundColor Green ""$"$Inputname type confirmed with .GetType() cmlet: " -NoNewline
                Write-Host $InputData.GetType()

            Write-Host -ForegroundColor DarkGray "*Finished*"

    #A function to remove multiple values from an array
    Function RemoveArrayValues ($Array,$RemoveValues)
        Foreach ($value in $RemoveValues)
            $Array = $Array | ? {$_ -ne $value}
        Return $Array

    #Here I list environment variables and other variables i want to exclude from view..
    $ExcludeVar = '$','?','^','args','ConfirmPreference','ConsoleFileName','DebugPreference','Error','ErrorActionPreference','ErrorView','ExecutionContext','false','FormatEnumerationLimit',

    #Get all variables
    $allVariables = (Get-Variable).Name

    #Remove excludevariableslist
    $allVariables = RemoveArrayValues $allVariables $ExcludeVar
    Foreach ($var in $allVariables)
        $checkvar = Get-Variable -Name $var
        CheckVariableType $checkvar.Value $var

    #Default value of the switch is false
    $Full = $false

Run as follows



I cant believe that I didn’t know about this until today, even though I have been Power-shelling for a few years now!

In the Windows PowerShell Integrated Scripting Environment (ISE) you are able to insert logical snippets by setting your curser in the script pane and pressing the keys: Ctrl + j.

This means you can use less time remembering syntax and more time solving your tasks.

Happy Powershelling!

When posting code on your wordpress blog, you will quite often find yourself editing your posts 3 seconds after publishing them. You might have noticed like me that WordPress alters certain characters in posted code, which can be really annoying when you post like 300 lines of Powershell code:-)

To get past this problem, I created a script that corrects the characters that has been changed by Wordpress.
Simply copy your edited text into a text file and save it anywhere on your computer. Then run the code under, point to your file when the “open file dialog box” appears. I hope this saves you a bit of frustration, it has for me!
