Powershell apply verbosity at a global level

Imagine if you have a script containing a single line of code like 

ni -type file foobar.txt

where the -verbose flag is not supplied to the ni command. Is there a way to set the Verbosity at a global PSSession level if I were to run this script to force verbosity? The reason I ask is that I have a group of about 60 scripts which are interdependent and none of these supply -verbose to any commands they issue and I'd like to see the entire output when I call the main entry point powershell script.

Solution

  • Use $PSDefaultParameterValues:

    $PSDefaultParameterValues['New-Item:Verbose'] = $true

    Set that in the Global scope, and then the default value of -Verbose for the New-Item cmdlet will be $True.

    You can use wildcards for the cmdletsyou want to affect:

    $PSDefaultParameterValues['New-*:Verbose'] = $true

    Will set it for all New-* cmdlets.

    $PSDefaultParameterValues['*:Verbose'] = $true

    will set it for all cmdlets.
