# Common parameters

# 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.

PS C:\> Write-Error "test" -ErrorAction Continue ; Write-Host "Second command"

-ErorrAction Continue (opens new window)

# -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.

PS C:\> Write-Error "test" -ErrorAction Ignore ; Write-Host "Second command"

-ErorrAction Ignore (opens new window)

# -ErrorAction Inquire

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

PS C:\> Write-Error "test" -ErrorAction Inquire ; Write-Host "Second command"

-ErorrAction Inquire (opens new window)

# -ErrorAction SilentlyContinue

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

PS C:\> Write-Error "test" -ErrorAction SilentlyContinue ; Write-Host "Second command"

-ErorrAction SilentlyContinue (opens new window)

# -ErrorAction Stop

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

PS C:\> Write-Error "test" -ErrorAction Stop ; Write-Host "Second command"

-ErorrAction Stop (opens new window)

# -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. To learn more about Workflow system, see [topic not yet created].
