-ExcludeProperty in PowerShell Core

Words: 183

A while ago I talked about an issue that I had in Windows PowerShell when I was trying to use the -ExcludeProperty parameter of Select-Object.

In case you missed it, it was one of my first posts, you can read it here.

Browsing StackOverflow

Checking out other peoples code is a great way to get exposed to different coding styles and ideas so I like to get a daily email of PowerShell questions from StackOverflow.

In the comments of one of these questions, Michael Klement ( twitter ) pointed out something, a little detail that I didn’t know but really appreciate.

There is a difference between Select-Object in Windows PowerShell and PowerShell Core

Difference

Let’s take a basic example

Windows PowerShell

# Doesn't work but doesn't work *silently*
[PSCustomObject]@{
    Version = $PSVersionTable.PSVersion
    Redundant = [Guid]::NewGuid()
} | Select-Object -ExcludeProperty Redundant

# Works
[PSCustomObject]@{
    Version = $PSVersionTable.PSVersion
    Redundant = [Guid]::NewGuid()
} | Select-Object -ExcludeProperty Redundant -Property *

PowerShell Core

[PSCustomObject]@{
    Version = $PSVersionTable.PSVersion
    Redundant = [Guid]::NewGuid()
} | Select-Object -ExcludeProperty Redundant

More Intuitive

Sometimes I’m more excited about the little things as I think they are more impactful. I’m excited about this.

The more you know!
