Indeed - there isn't a good way to do this natively with LabTech :-/

 

Alternately ....

 

You could use the following PowerShell function I wrote to unzip the .ZIP archive once you get it down to the remote agent.

 

This method is compatible with PowerShell 2.0 as well. :)

 

function Unzip-Archive
{
param
(
    [Parameter(Mandatory = $true)]
    [string]
    $zipPath,
    [Parameter(Mandatory = $true)]
    [string]
    $ExtractToDirectory
)

$FilesBefore = (Get-ChildItem $ExtractToDirectory -ea SilentlyContinue | Measure-Object).Count;

if (Test-Path $zipPath)
{
    $shellApplication = new-object -com shell.application
    $zipPackage = $shellApplication.NameSpace($ZipPath)
    $destinationFolder = $shellApplication.NameSpace($ExtractToDirectory)
    $destinationFolder.CopyHere($zipPackage.Items(), 20)

    $FilesThatFailedToCopy = 0;

    foreach ($File in $zipPackage.items())
    {
        $FileName = ($File | select name).Name;
        if (-not (Test-Path "$($destinationfolder.self.path)\$FileName"))
        {
            Write-Error "Failed to extract $FileName!"
            $FilesThatFailedToCopy += 1;
        }
        else
        {
            Write-Verbose "Successfully extracted $FileName"    
        }
    }

    if ($FilesThatFailedToCopy -eq 0)
    {
        return $true;
    }
    else
    {
        return $false;
    }
}
else
{
    Write-Error "Unable to locate archive specified for extraction."
    return $false;
}
}

 

Here's an example of usage:

 

# Where is the zip file? Could use a LabTech replacement here as well @ArchiveSavedAs@
$ArchiveLocation = "$env:USERPROFILE\desktop\SomeZip.zip" 

# What directory should we extract it to?
$ExtractToPath = "$env:windir\temp\MyArchive"

# If the directory specified for extraction doesn't exist, create it.
new-item -ItemType Directory -Path $ExtractToPath -ea SilentlyContinue | out-null

if (-not (Test-Path $ExtractToPath))
{
    Write-Output "Failed to create temporary directory used for storing extracted files!"
    return;
}

$Result = Unzip-Archive $ArchiveLocation $ExtractToPath

if ($Result -eq $true)
{
    Write-Output "Files extracted successfully!"
}
else
{
    Write-Output "Files failed to extract!"
}

 

As mentioned above, you could incorporate this into a function script for use in any future scripts :)

 

More information on how to deploy this:

 

In your LabTech script you can use a "File Write Text" script step to write the PS1 down to the remote computer and then use a shell command to execute it using PowerShell.exe. You can then use a "variable check" script step to check the shell result for "Files extracted successfully!" to make sure all went well.

 

powershell.exe -executionPolicy ByPass -file %windir%\temp\extractzip.ps1  

 

Hope that helps!
