Write-Host "checking users"$testUser="hgallo"
$checkUser = Get-WmiObject -Class Win32_UserAccount -Filter  "LocalAccount='True'"  | Select-String -Pattern $testUser

if($checkUser -ne $null) {
  Write-Host "user $testUser found"
} else {
  Write-Host "user $testUser not found"    
}

this is my homework and im not good at coding guys can you help me pleases.

Here is the error Select-String: 

Cannot bind argument to parameter 'Pattern' because it is null. 
At line:1 char:107

  • The question has some serious formatting problems. It's hard to say whether it's just bad copy-paste or it is real code. Either way, this might be just a typo in the first `write-host` statement or something way different. As of now, it's all guessning. – vonPryz Jan 29 '17 at 21:12

VonPryz is correct,

Please try the below code

Write-Host "checking users"
$testUser="hgallo"

$checkUser = Get-WmiObject -Class Win32_UserAccount -Filter  "LocalAccount='True'"  | Select-String -Pattern $testUser

if($checkUser -ne $null) {
  Write-Host "user $testUser found"
} else {
  Write-Host "user $testUser not found"    
}

The error in the code was stating that the -Pattern parameter was failing because the variable $testuser was null. This was because of the formatting on your first line of code.

Incorrectly Formatted Code:

Write-Host "checking users"$testUser="hgallo"

Correctly Formatted Code:

Write-Host "checking users"
$testUser="hgallo"

    all you are doing there is creating a variable called '$testUser' and adding a string "shu" to it. Look into this link: http://stackoverflow.com/questions/15167069/powershell-create-local-user-account – Lachie White Jan 30 '17 at 06:54
