Is this AD group still used?

That’s a pretty hard question to answer, and it depends on how the group is used.

But one way of verifying this is to check when any of it’s members logged on last time. There is an obvious risk that the group is not used for anything in particular but it still might have users/computers in it, but it might give you a hint.

I therefor wrote an advanced function that can help you with this.

It’s pretty straight forward to use, just write:

Get-ADGroupLastUsed -Identity "Domain Admins" -Recursive

The “Recursive”-switch makes it resolve the members in all child groups. It works for both user and computer objects.

This can be pretty useful in certain scenarios, and I hope it might be of use for you too!

The code is available at PoshCode.Org using this link.

Save thumbnailPhoto to file with PowerShell (Get-ADThumbnail)

A while back I wrote an advanced function for uploading a picture to Active Directory (ConvertTo-ADThumbnail), but I never wrote a function for downloading the picture and save it on disk, so here it is!

It has two parameters, Identity and Path. Identity is the SamAccountName, DistinguishedName, ObjectGUID or SID of the user(s) which photo you want to save on file, and Path is the folder path were it should be save. It saves the file with the name “SamAccountName.jpg”.

This can be useful if you want to verify which picture is actually uploaded to a certain user.

You could also download the pictures of all the people called ‘John’ in your Active Directory with the oneliner:

Get-ADUser -Filter "GivenName -eq 'John'" | Get-ADThumbnail -Path C:\Temp\

I hope someone might have use for this function which is available at through this link.

Checking TV Show schedules with PowerShell

Remember the post about buying groceries with PowerShell? One of the usage examples suggested that you could order some snacks when a tv show you like is having a season finale (or premiere for that matter!).

But how to check for this in an automated way? With PowerShell of course 🙂

I’ve written two advanced functions for doing this:

  • Get-TVShowNextAirDate retrieves a list of most tv shows that are currently airing and is listing their next airdate.
  • Get-TVShowAirDate retrieves all known airdates of the tv show specified (supports pipelining! 😉 )

Screenshot of these in action:

That’s all the tools you need to automate your popcorn order! 😉

As always, the code has been uploaded to PoshCode.Org and can be viewed through this link (Updated 2016-10-06).

Happy automating anything!
