Using PowerShell to check if an ADUser is disabled to enable or enabled to disabled

Good morning experts,

This morning I received two lists for checking - both of Adjunct instructors in our college.
One list has the current instructors, who should be enabled in active directory and the second contains Adjuncts who left us and need to be disabled.

I  need to learn to use an if statement to check if a certain person is enabled to disable him/her: Something like the following in correct PowerShell syntax:

if (InstructorName enabled == true)
{
InstructorName enabled = false;
}

Thank you for your help
Adam

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Usually it is much more simple to just force-disable / enable accounts, without performing checking.
Get-Content C:\InstructorsToEnable.txt | % { Set-ADUser $_ -enabled $true }
Get-Content C:\InstructorsToDisable.txt | % { Set-ADUser $_  -enabled $false }

Open in new window

You could perform a check, of course. The first case might look like this:
Get-Content C:\InstructorsToEnable.txt | % {
  if (!(Get-ADUser $_).Enabled)
  {
    Set-ADUser $_ -enabled $true }
  }
}

Open in new window

Or
Get-Content C:\InstructorsToEnable.txt |
  % { Get-ADUser $_ } |
  ? { !$_.Enabled } | % {
    Set-ADUser $_ -enabled $true
  }

Open in new window

Sadly no. But you only need to know a few basics about PowerShell, and a few about ActiveDirectory, to be able to run simple tasks. Most of it is trying out anyway, and PS is a great tool for doing that.
