Getting additional error messages

In this recipe, we will learn to display additional error messages.

How to do it...

Let's take a look at how to display more error messages.

1. Open the PowerShell ISE. Go to Start | Accessories | Windows PowerShell | Windows PowerShell ISE.

2. Add the following script and run it:

   Clear-Host
   $error[0] | Format-List -Force

How it works...

PowerShell supports some special variables and constants. Some of these display arguments, user directories, and other settings. The $error is an array variable that holds all the error objects that are encountered in your PowerShell session. To display the last error message, you can use the following:

$error[0] | Format-List -Force

To check the number of errors contained in your variable, you can use the following:

$error.Count

$error works like a circular buffer. By default, $error stores the last 256 errors in your session. If you want to increase the number of error objects the array can store, you can set the $MaximumErrorCount variable...
