r/PowerShell on Reddit: Better Way to Create If/Elseif/Else Statement
August 14, 2021 -
Hey Everyone!
I am fairly new to PowerShell and wanted to get some guidance on a potentially better way to utilize an If/Elseif/Else statement I have been using in an Active Directory script I made.
The following code snippet works great, but I have a feeling there is a much cleaner or efficient way of doing this. As you can see the more OU's present in the AD environment the more this elseif list grows. In the script that I used in a production environment, this list grew quite large as there was approximately 15 OUs present.
Is there a more efficient way to do this?
if ( $userdepartment -eq "IT" )
{
Get-ADUser "$($uservaluefirstletter)$($uservaluelast)".ToLower() | Move-ADObject -TargetPath 'OU=IT,OU=testlab.local Users,DC=testlab,DC=Local'
}
elseif ( $userdepartment -eq "Engineering" )
{
Get-ADUser "$($uservaluefirstletter)$($uservaluelast)".ToLower() | Move-ADObject -TargetPath 'OU=Engineering,OU=testlab.local Users,DC=testlab,DC=Local'
}
elseif ( $userdepartment -eq "Finance" )
{
Get-ADUser "$($uservaluefirstletter)$($uservaluelast)".ToLower() | Move-ADObject -TargetPath 'OU=Finance,OU=testlab.local Users,DC=testlab,DC=Local'
}
elseif ( $userdepartment -eq "Human Resources" )
{
Get-ADUser "$($uservaluefirstletter)$($uservaluelast)".ToLower() | Move-ADObject -TargetPath 'OU=Human Resources,OU=testlab.local Users,DC=testlab,DC=Local'
}
elseif ( $userdepartment -eq "Sales" )
{
Get-ADUser "$($uservaluefirstletter)$($uservaluelast)".ToLower() | Move-ADObject -TargetPath 'OU=Sales,OU=testlab.local Users,DC=testlab,DC=Local'
}
else
{
Write-Warning "Department $userdepartment could not be found."
}Thank you to anyone who takes the time to read this and gives guidance on this!

You are doing the same thing in all cases, so really you could simplify the whole thing to if($userdepartment -in 'IT', 'Engineering', 'Finance', 'Human Resources', 'Sales') { Get-ADUser "$($uservaluefirstletter)$($uservaluelast)".ToLower() | Move-ADObject -TargetPath "OU=$userdepartment,OU=testlab.local Users,DC=testlab,DC=Local" } else { Write-Warning "Department $userdepartment could not be found." }

One option is to use a switch statement. You define user department as the variable to evaluate and it executes any code associated with any values that match in a predefined list.

July 10, 2019Does PowerShell support a ternary operator like other languages do?
Yes, with PowerShell 7 and later, you can use a ternary operator. The syntax is:
$result = $condition ? 'TrueValue': 'FalseValue'
This is an efficient way for simple conditional assigning.
$result = $condition ? 'TrueValue': 'FalseValue'
This is an efficient way for simple conditional assigning.

What is short-circuiting in PowerShell conditions?
In this context, short-circuiting is related to how PowerShell evaluates conditions and is used by operators such as -and and -or. For example, '-and' would only evaluate the second condition if the first condition was $true, whereas '-or' would not evaluate the second condition if the first condition was $false. In both situations, the short-circuiting behaviour saves time and avoids unnecessary evaluations.

Can I have multiple elseif statements in one script?
Yes, you can. PowerShell supports multiple elseif statements in the same script. They are evaluated in a top-to-bottom manner, and the first condition set to $true will run; everything else will be skipped out of the elseif statement.

You have to spell that out for powershell
a switch statement could do that for you though 
it’s not case sensitive, unless you tell it to.

So, I think we’re gonna see a few posts from me today as I continue to debug this script… If I just need to update one singular post as we go, let me know. But I’m sure each issue is going to be a little different and spread out.
I’m building upon an AD User creation script I’ve written and am in need of a little more flexibility. The company sometimes creates multiple AD user objects for a singular person depending on if they are also needed at the “sister company” (literally the building next door…) Nothing is really separated in terms of AD forests, but I do sort them into a separate container and label them so that it’s easier to find/sort. So I want the script to prompt if this is a “OtherCompany” user, and change the variables automatically.
Now, onto the script… I’m attempting to set variables inside this If / ElseIf statement, and it doesn’t appear to be working. If I run this code inside ISE and then check ($DISPLAYNAME) in the console… it displays
Test User (OtherCompany)
This happens whether or not I say “Y” or “N”.
# Set additional required variables with input given for user
$DISPLAYNAME = "$FirstName $LastName"
$SAM = $FirstName + $LastName.SubString(0,1)
$DNSROOT = '@' + (Get-ADDomain).dnsroot
$UPN = $SAM + “$DNSROOT”
Write-Host "Is this an OtherCompany user?" -ForegroundColor Yellow
$ISResponse = Read-Host "[Y] Yes, [N] No"
if ($ISResponse -eq "y" -or "Y") {
$COMPANY = "OtherCompany"
$DISPLAYNAME = "$DISPLAYNAME (OtherCompany)"
$EmployeeEmail "$FirstName.$LastName@othercompany.com"
$SAM = "$SAM-IS"
$UPN = $SAM + "$DNSROOT"
} elseif ($ISResponse -eq "n" -or "N"){
$COMPANY = "Contoso"
$EmployeeEmail = "$FirstName.$LastName@contoso.com"
}
Now, I’m seeing some conflicting information online. A few different posts say that Powershell does not support conditional assignment (interesting for a scripting language…) but that answer doesn’t hold up when I use another script I wrote. This one converts IP addresses for a Barracuda web/email filter. The only difference I can ascertain is that I’m using -like rather than -eq in this script… but this works as expected
