Question

My case    ErrorActionPreference    Stop    1 -  ErrorActionPreference   Get-ChildItem NoSuchFile txt -ErrorAction SilentlyContinue   2 -  ErrorActionPreference   Get-ChildItem NoSuchFile txt -ErrorAction Stop   3 -  ErrorActionPreference     Output      1 - Stop    2 - Stop    and display an error      Now    ErrorActionPreference    Stop    1 -  ErrorActionPreference    Get-PSSessionConfiguration -Name  MyShellUri  -ErrorAction SilentlyContinue   2 -  ErrorActionPreference     Output      1 - Stop    and display an error       Why doesn t work -ErrorAction SilentlyContinue  for Get-PSSessionConfiguration    Update   Now    ErrorActionPreference    Continue   1 -  ErrorActionPreference    Get-PSSessionConfiguration -Name  MyShellUri  -ErrorAction SilentlyContinue   2 -  ErrorActionPreference     Output      1 - Continue    2 - Continue    Now    ErrorActionPreference    SilentlyContinue   1 -  ErrorActionPreference    Get-PSSessionConfiguration -Name  MyShellUri  -ErrorAction SilentlyContinue   2 -  ErrorActionPreference     Output      1 - SilentlyContinue    2 - SilentlyContinue    This reference   The ErrorAction ubiquitous parameter can be used to silence non-terminating errors using the parameter value SilentlyContinue and it can be used to convert non-terminating errors to terminating errors using the parameter value Stop   However it can t help you ignore terminating errors and in this case Stop-Transcript is throwing a terminating error   If you want to ignore  use a try catch e g    try   Stop-Transcript   catch

A solution for me    old ErrorActionPreference    ErrorActionPreference  ErrorActionPreference    SilentlyContinue  if  Get-PSSessionConfiguration -Name  MyShellUri  -ErrorAction SilentlyContinue  -eq  null       WriteTraceForTrans  The session configuration MyShellUri is already unregistered     else               Unregister-PSSessionConfiguration -Name  MyShellUri  -Force -ErrorAction Ignore    ErrorActionPreference    old ErrorActionPreference    Or use try-catch  try      Get-PSSessionConfiguration -Name  MyShellUri  -ErrorAction SilentlyContinue      catch

It looks like that s an  unhandled exception   meaning the cmdlet itself hasn t been coded to recognize and handle that exception   It blew up without ever getting to run it s internal error handling  so the -ErrorAction setting on the cmdlet never came into play

Tip  2  Can t you use the classical 2 gt  redirection operator    Get-PSSessionConfiguration -Name  MyShellUri  -ErrorAction SilentlyContinue  2 gt   NULL if           foo      I don t like errors so I avoid them at all costs
