ErrorActionPreference and ErrorAction SilentlyContinue for Get-PSSessionConfiguration
error-handling, powershell, silent
Solution
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 {
}
Problem
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 {} ```
