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.

Accepted Answer

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.
