Question:
Is there an easy way to make the -Verbose switch “passthrough” to other function calls in Powershell?
I know I can probably search $PSBoundParameters for the flag and do an if statement:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
[CmdletBinding()] Function Invoke-CustomCommandA { Write-Verbose "Invoking Custom Command A..." if ($PSBoundParameters.ContainsKey("Verbose")) { Invoke-CustomCommandB -Verbose } else { Invoke-CustomCommandB } } Invoke-CustomCommandA -Verbose |
It seems rather messy and redundant to do it this way however… Thoughts?
Answer:
One way is to use $PSDefaultParameters at the top of your advanced function:
|
1 2 |
$PSDefaultParameterValues = @{"*:Verbose"=($VerbosePreference -eq 'Continue')} |
Then every command you invoke with a -Verbose parameter will have it set depending on whether or not you used -Verbose when you invoked your advanced function.
If you have just a few commands the do this:
|
1 2 3 |
$verbose = [bool]$PSBoundParameters["Verbose"] Invoke-CustomCommandB -Verbose:$verbose |
