cmdlets - User input in automated powershell scripts -

i writing powershell script executes several powershell cmdlets sequentially. 1 of cmdlets among them asks user input [y/n]. want pass value y always. there way this?

sounds need change $confirmpreference variable.

from output of get-help about_preference_variables:

$confirmpreference ------------------ determines whether windows powershell automatically prompts confirmation before running cmdlet or function.   when value of $confirmpreference variable (high, medium, low) less or equal risk assigned cmdlet or function (high, medium, low), windows powershell automatically prompts confirmation           before running cmdlet or function.  if value of $confirmpreference variable none, windows powershell never automatically prompts before running cmdlet or function. 

so, in order suppress confirmation message, do:

$confirmpreference = "none" <# script here #> 

you can on per-cmdlet basis, -confirm:$false parameter:

set-aduser -description $desc -confirm:$false 

note works if cmdlet supports common parameter confirmation. won't have impact on homegrown cmdlets funky self-made confirmation logic
