Powershell apply verbosity at a global level

Question

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.

Answer 1

You could also do:

$global:VerbosePreference = 'continue'

Works better then PSDefaultParameters as it tolerates function not having Verbose param.

Answer 2

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.
