How can I execute scripts in a code created powershell shell that has Write-Host commands in it? -

i have script writing relies on functions in imported module. script takes while due io (web requests) , parallize hundreds of thousands of iterations of script block.

after attempting several different methods (with little success due restrictions start-job , other things) current implementation relies on pre-creating pool of powershell "shells" created via $shell = [powershell]::create().

one of module methods have phone call bootstrap shell (so it's in right state) has phone call write-host in it. when phone call $shell.invoke() next error occurs:

write-host : command prompts user failed because host programme or command type not back upwards user interaction. seek host programme supports user interaction, such windows powershell console or windows powershell ise, , remove prompt-related commands command types not back upwards user interaction, such windows powershell workflows.

now, since module custom can remove write-host calls, reduces user friendliness when run straight end users. can create switch parameter not execute write-host if parameter true, downwards line bit of work (feasible, i'd rather not).

is there way can write-host not error out in scenario? don't care input in scenario, don't want errors.

the fastest way work define dummy write-host function in script, or define in runspace independently before running script.

$ps.addscript("function write-host {}").invoke() $ps.commands.clear() # can invoke scripts utilize write-host # sense free implement write-host writes log file

simple that. reason you're getting error because programmatic invocation not expect user interaction. there ways create work employs different apis.
