42. Common parameters

Note

The below information is extensively based in information taken from the PowerShell® Notes for Professionals book. I plan to extend this information based on my day to day usage of the language.

42.1: ErrorAction parameter

Possible values are Continue | Ignore | Inquire | SilentlyContinue | Stop | Suspend.

Value of this parameter will determine how the cmdlet will handle non-terminating errors (those generated from Write-Error for example; to learn more about error handling see [ topic not yet created ]).

Default value (if this parameter is omitted) is Continue.

-ErrorAction Continue

This option will produce an error message and will continue with execution.

1
Write-Error "test" -ErrorAction Continue ; Write-Host "Second command"

-ErrorAction Ignore

This option will not produce any error message and will continue with execution. Also no errors will be added to $Error automatic variable.

This option was introduced in v3.

1
Write-Error "test" -ErrorAction Ignore ; Write-Host "Second command"

-ErrorAction Inquire

This option will produce an error message and will prompt user to choose an action to take.

1
Write-Error "test" -ErrorAction Inquire ; Write-Host "Second command"

-ErrorAction SilentlyContinue

This option will not produce an error message and will continue with xecution. All errors will be added to $Error automatic variable.

1
Write-Error "test" -ErrorAction SilentlyContinue ; Write-Host "Second command"

-ErrorAction Stop

This option will produce an error message and will not continue with execution.

1
Write-Error "test" -ErrorAction Stop ; Write-Host "Second command"

-ErrorAction Suspend

Only available in Powershell Workflows. When used, if the command runs into an error, the workflow is suspended. This allows investigation of such error and gives a possibility to resume the workflow.
