How can I parse the text from these results into parameters for a separate script?

Question

I need to extract client_TargetText and AnotherTargetText_110953_140521 from the results I get when running the whoami /groups command:

How would I go about grabbing client_TargetText and removing the client_ so it becomes just TargetText and then make this $Param1 in the script below? (client_ is always present in the text I need to grab for $Param1)

Then how would I go about grabbing AnotherTargetText_110953_140521 so it can be made into $Param2 in the script below? (The desired text for $Param2 is always suffixed by 6digits_6digits in these AD groups)

My goal is to somehow send this text over into a script I use for creating server shortcuts on user desktops.

The results will be different for each user when whoami runs so I think the only wildcards that can be used are client_ and 6digits_6digits. Any helping me towards finding this answer very much appreciated as I am trying to learn how this would work but can't figure it out.

The script below is the desired outcome after successfully parsing those two pieces of text over and turning them into $Param1 and $Param2:

function set-shortcut {
param ( [string]$SourceLnk, [string]$DestinationPath )
    $WshShell = New-Object -comObject WScript.Shell
    $Shortcut = $WshShell.CreateShortcut($SourceLnk)
    $Shortcut.TargetPath = $DestinationPath
    $Shortcut.Save()
    }

    try{

$Param1 = TargetText
$Param2 = AnotherTargetText_110953_140521
$SourcePath = \\server\data\designs\$Param1\$Param2\data_store"

set-shortcut "%USERPROFILE%\Desktop\data_store.lnk" "$SourcePath"

     "This worked"
     
pause
}

catch
   {
    
    "This didn't work"
}
pause

If this is being ran with PowerShell:

1. Let's use the proper opening, and closing quotes ("").
2. Let's also use the proper environment variables: $env:USERPROFILE.

I really couldn't make too much sense in what you were trying to accomplish, so I did what I think you meant. As far as your parameters for your function, that i'm still lost on.

function Set-ShortCut {
    Param ( 
        [string]$SourceLnk, 
        [string]$DestinationPath 
    )
        
        $WshShell = New-Object -comObject WScript.Shell
        $Shortcut = $WshShell.CreateShortcut($SourceLnk)
        $Shortcut.TargetPath = $DestinationPath
        $Shortcut.Save()

}


$Groups = Whoami /Groups /FO CSV | ConvertFrom-Csv

$Param1, $Param2 = $Groups.'Group Name'.Where{
    
        $_ -match 'client_' -or `
        $_ -match '(_\d{6}){2}'

    } -replace 'client_|MYDOMAIN\\'



$SourcePath = "\\server\data\designs\$Param1\$Param2\data_store"

Set-ShortCut -SourceLnk "$env:USERPROFILE\Desktop\data_store.lnk" -DestinationPath $SourcePath

Luckily, whoami has a /FO CSV option which we can use to convert it to a proper PowerShell object using ConvertFrom-Csv. After the object conversion, we can use some Regex matching to get what you're after assuming that's exactly how the names are displayed. Please note the double assignment of $Param1, and $Param2 as it splits the results into those two variables. Also, in trying to avoid the pipeline, I used the .Where()\{} operator (yes, it's considered an operator) for faster parsing.

I would suggest in looking into the the cmdlet mentioned by @Lee_Daily, to include the method he provide in getting the results you're after.

EDIT: You can try separating the filtering into two variables for explicit filtering. Although not the best solution, it should work:

function Set-ShortCut {
    Param ( 
        [string]$SourceLnk, 
        [string]$DestinationPath 
    )
        
        $WshShell = New-Object -comObject WScript.Shell
        $Shortcut = $WshShell.CreateShortcut($SourceLnk)
        $Shortcut.TargetPath = $DestinationPath
        $Shortcut.Save()

}

$Groups = WhoAmI /Groups /FO CSV | ConvertFrom-Csv

$Param1 = $Groups.'Group Name'.Where{ $_ -match 'client_' } -replace 'client_|MYDOMAIN\\'
$Param2 = $Groups.'Group Name'.Where{ $_ -match '(_\d{6}){2}' } -replace 'MYDOMAIN\\'

$SourcePath = "\\server\data\designs\$Param1\$Param2\data_store"

Set-ShortCut -SourceLnk "$env:USERPROFILE\Desktop\data_store.lnk" -DestinationPath $SourcePath
