Why ScriptBlock in PowerShell delays output until the ScriptBlock completes?
I have this code:
Function-Step "Long operation" { MyLongRunningFunction }
function Function-Step
{
param([string]$message,[ScriptBlock]$block)
Write-Host $message
Read-Host
$block.Invoke()
}
MyLongRunningFunction writes information to the standard output as it runs, but it doesn't show in the console until the function finishes, suddenly.
MyLongRunningFunction
It seems that it's eating all the output of MyLongRunningFunction ends, and after that, it throws all the output at the same time.
MyLongRunningFunction
How can I avoid this behavior?
$block.Invoke() -> & $block– PetSerAl

$block.Invoke()
& $block
Use @PetSerAl Answer. That will keep the handle with the function itself.
