Get-ADUser doesn’t display all properties

Microsoft’s Active Directory cmdlets have some issues. One of the ones that catches everyone when they start using them is that Get-ADUser doesn’t display all properties.

A default call to Get-ADUser displays a subset of the available properties of the user object:

DistinguishedName : CN=FOX Fred,OU=UserAccounts,DC=Manticore,DC=org
Enabled           : True
GivenName         :
Name              : FOX Fred
ObjectClass       : user
ObjectGUID        : db5a3975-980d-4749-b9c0-48aff9217b2a
SamAccountName    : foxfred
SID               : S-1-5-21-759617655-3516038109-1479587680-1314
Surname           :
UserPrincipalName :

Even if the properties are empty – such as Givenname and Surname – the property name is displayed. So, how do you get the properties that aren’t part of the default list?

There’s the brute force approach:

PS> Get-ADUser -Identity foxfred -Properties *

Using –properties * returns ALL of the properties of a user. That’s OK if you’re looking at one, or a few users, but becomes a very expensive operation if you’re looking at thousands of user objects.

A more elegant approach is to specify the properties you want:

PS> Get-ADUser -Identity foxfred -Properties EmailAddress, LockedOut, ProtectedFromAccidentalDeletion, whenCreated

DistinguishedName               : CN=FOX Fred,OU=UserAccounts,DC=Manticore,DC=org
EmailAddress                    :
Enabled                         : True
GivenName                       :
LockedOut                       : False
Name                            : FOX Fred
ObjectClass                     : user
ObjectGUID                      : db5a3975-980d-4749-b9c0-48aff9217b2a
ProtectedFromAccidentalDeletion : False
SamAccountName                  : foxfred
SID                             : S-1-5-21-759617655-3516038109-1479587680-1314
Surname                         :
UserPrincipalName               :
whenCreated                     : 17/11/2016 14:07:13

You get the properties you specified and the default properties.

So, while Get-ADUser doesn’t display all properties you can overcome this by using the –properties parameter with a * for all properties or a list of the properties you want in addition to the defaults.

Filtering of Objects and Properties

Saw a post on the forum today that suggests people are still confused about how to perform filtering of objects and properties in PowerShell.

As with so much in PowerShell explanations are always better with examples.

Let’s start with the physical disks in a computer:

PS> Get-PhysicalDisk

FriendlyName               SerialNumber    CanPool OperationalStatus HealthStatus Usage            Size
------------               ------------    ------- ----------------- ------------ -----            ----
Toshiba USB 2.0 Ext. HDD   WD-WCAMR3209671 False   OK                Healthy      Auto-Select 298.09 GB
ST916082 1A                DEF10E8D9B36    False   OK                Healthy      Auto-Select 149.05 GB
Samsung SSD 840 PRO Series S1AXNSAF329511V False   OK                Healthy      Auto-Select 476.94 GB

If you want to objects that match a specific criteria – for instance disk is larger than 300GB:

PS> Get-PhysicalDisk | Where-Object Size -gt 300GB

FriendlyName               SerialNumber    CanPool OperationalStatus HealthStatus Usage            Size
------------               ------------    ------- ----------------- ------------ -----            ----
Samsung SSD 840 PRO Series S1AXNSAF329511V False   OK                Healthy      Auto-Select 476.94 GB

Where-Object is your friend.

What you’re actually doing – though very few people actually write it like this – is

Get-PhysicalDisk | Where-Object -Property Size -GT -Value 300GB

The help file for Where-Object lists the possible operators.

You can also show the original style syntax

Get-PhysicalDisk | Where-Object -FilterScript {$_.Size -gt 300GB}

Normal usage is to not write the –FilterScript parameter so it becomes

Get-PhysicalDisk | Where-Object {$_.Size -gt 300GB}

$_ represents the object currently on the pipeline. If you need to use multiply conditions in your filter you’ll need to use the older style syntax.

So far you’ve seen how reduce the number of objects on the pipeline. Where-Object filters out those that don’t match the given criteria.

If you want to reduce the number of properties that the objects on the pipeline possess you’ll need to use Select-Object

PS> Get-PhysicalDisk | Select-Object -Property FriendlyName, HealthStatus, Size

FriendlyName               HealthStatus         Size
------------               ------------         ----
Toshiba USB 2.0 Ext. HDD   Healthy      320072933376
ST916082 1A                Healthy      160041885696
Samsung SSD 840 PRO Series Healthy      512110190592

More commonly written as

Get-PhysicalDisk | Select FriendlyName, HealthStatus, Size

PowerShell best practice is always to use the full cmdlet and parameter names in your scripts. The *-Object cmdlets and in particular Where-Object, Sort-Object and Select-Object are often abbreviated to Where, Sort and Select and the parameters only used where necessary.  This was the way I was advised to use them by Jeffrey Snover – who invented PowerShell –  when I wrote PowerShell in Practice. Good enough for me.

PowerShell Summit 2017 – – more seats available

After selling out in record time we’ve managed to squeeze a few more seats in after discussion with the conference centre.

Those seats are live now.

They are very definitely, the absolute last set of seats we’ll be able to add this year.

First come – First served. When they’re gone – they’re gone

Append data to a file

A question on the forums – the user wanted to append data to a file. This is a common scenario when you’re creating a log file.

There’s 2 easy ways to do this.

Lets create a couple of variables with multi-line data

PS> $data = @’
>> This is
>> multiline data
>> ‘@
PS> $data
This is
multiline data

PS> $data2 = @’
>> This is
>> more multiline
>> data
>> ‘@
PS> $data2
This is
more multiline

First you could use Out-File

PS> Out-File -FilePath of.txt -InputObject $data
PS> Out-File -FilePath of.txt -InputObject $data2 -Append
PS> Get-Content -Path of.txt
This is
multiline data

This is
more multiline

First time you call Out-File you don’t have to use –Appemd but you can. On subsequent calls use -Append to add the data – if you don’t the file will be overwritten with the new data.

Second option is one you don’t see so much – Add-Content. In earlier versions of PowerShell this was your only option

PS> Add-Content -Path ac.txt -Value $data
PS> Add-Content -Path ac.txt -Value $data2
PS> Get-Content -Path ac.txt
This is
multiline data

This is
more multiline

If the file doesn’t exist Add-Content will create it.

Two ways to append data to your file
