This post is quite old, but it is useful. It's now PS 2.0, and I do not understand the following behaviour:

$p = @{e=1;k=2}

$x = New-Object -Property $p -TypeName psobject

$x, (Get-Process powershell) | ft

k e

- -

2 1

(There is no process object displayed.)

[21] PS C:\> (Get-Process powershell),$x | Format-Table

Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName

------- ------ ----- ----- ----- ------ -- -----------

807 23 49452 50408 570 4,53 3412 powershell

k : 2

e : 1

(There are both the process object and the custom object displayed, process is in table format, custom object is in list format.)

Why?

Either you modify the default .ps1xml files (**not recommended**) or you simply drop your update-formatdata into your profile to run it everytime (notepad $profile).

This document gives an overview of the schema:

Now, what do I have to do to make the formatting permanent? If I run Update-FormatData, that only stays in effect while that instance of PowerShell is open.

PowerShell defines XML schema and a mechanism (the Update-FormatData cmdlet) where anyone can register views for an object type.

Where is the schema defined? I can reverse engineering bits of it from the ps1xml files that ship in RC1 but haven't been able to find anything beyond a few examples of user ps1xml files.
