Where, Variables and Functions in Powershell

Hi
I have this function, that should reveal all user accounts with some given letter combinations in the Description og Info field in AD.
Function RevealClearTextPassword([Array]$search){


    $words = $search -split ","


    foreach($word in $words){
        
        $list = $list += "(`$_.Description -like `"*$word*`" -OR `$_.info -like `"*$word*`") -OR "
    }

    $list = $list.substring(0,$list.Length-5)
    Get-ADUser -filter * -Properties enabled, Description, Info | Where{$list} | ft samaccountname,enabled,description,info -AutoSize
    
}

Open in new window

When I run the Function like this:
RevealClearTextPassword pwd,pw,kode,pass

Open in new window

it returns ALL users in the AD no matter what is written in the two fields.
Why is that?

If I write out the Get-ADUser line it looks ok:
Get-ADUser -filter * -Properties enabled, Description, Info | Where{($_.Description -like "*pwd*" -OR $_.info -like "*pwd*") -OR ($
_.Description -like "*pw*" -OR $_.info -like "*pw*") -OR ($_.Description -like "*kode*" -OR $_.info -like "*kode*") -OR ($_.Descrip
tion -like "*pass*" -OR $_.info -like "*pass*")} | ft samaccountname,enabled,description,info -AutoSize

Open in new window

As far as I can see it should work, but it doesn't.

When you mention Where{$list}, PowerShell consider it as a variable not a expression/condition. Until $list is not equal to $null the where condition is always considered as true.  That why the result has all users.

Change Where{$list} to Where{Invoke-Expression $list} and see if it works for you

You can also construct a pattern and use -Match to achieve the same..
Try..
Function RevealClearTextPassword([Array]$search){
  $words = ($search -Split ",") -join "|"
    Get-ADUser -filter * -Properties enabled, Description, Info | 
      ? {$_.Description -Match $words -OR $_.info -match $words} | 
    FT samaccountname,enabled,description,info -AutoSize
}

As an alternative to Subsun's, if you change lines 12 and 13 as below it should work.
$list = [scriptblock]::Create( ($list.substring(0,$list.Length-5)) )
    Get-ADUser -filter * -Properties enabled, Description, Info | Where $list | ft samaccountname,enabled,description,info -AutoSize
