Since version 3 PowerShell introduced $PSDefaultParameterValues which is a built-in preference variable which lets you specify default values for any cmdlet or advanced function. You can read much more about it inside the respective help file. In a nutshell $PSDefaultParameterValues is a hash-table where (in its most common version) the key consists of the cmdlet name and parameter name separated by a colon (:) and the value is the custom default value:
[code language=”powershell”]
:"="
[/code]
I've added the following default parameter values to my profile (You can read [here](http://www.computerperformance.co.uk/powershell/powershell_profile_ps1.htm) and [here](http://blogs.technet.com/b/heyscriptingguy/archive/2012/05/21/understanding-the-six-powershell-profiles.aspx) on how to work with profiles):
[code language="powershell"]
$PSDefaultParameterValues.Add("Get-ChildItem:Force",$true)
$PSDefaultParameterValues.Add("Receive-Job:Keep",$true)
$PSDefaultParameterValues.Add("Format-Table:AutoSize",$true)
$PSDefaultParameterValues.Add("Import-Module:Force",$true)
$PSDefaultParameterValues.Add('Export-Csv:NoTypeInformation', $true)
$PSDefaultParameterValues.Add('Get-Member:Force', $true)
$PSDefaultParameterValues.Add('Format-List:Property', '*')
$PSDefaultParameterValues.Add('Set-Location:Path', '..')
$PSDefaultParameterValues.Add('Get-Help:Detailed', $true )
[/code]
What are other default parameter values that you use?
