FUNCTION Get-DbaAgentJob {
    <#
  .SYNOPSIS
   Gets SQL Agent Job information for each instance(s) of SQL Server.
 
  .DESCRIPTION
   The Get-DbaAgentJob returns connected SMO object for SQL Agent Job information for each instance(s) of SQL Server.
 
  .PARAMETER SqlInstance
   SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
  .PARAMETER SqlCredential
   SqlCredential object to connect as. If not specified, current Windows login will be used.
 
  .PARAMETER Job
   The job(s) to process - this list is auto-populated from the server. If unspecified, all jobs will be processed.
 
  .PARAMETER ExcludeJob
   The job(s) to exclude - this list is auto-populated from the server.
 
  .PARAMETER NoDisabledJobs
   Switch will exclude disabled jobs from the output.
 
  .PARAMETER EnableException
   By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
   This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
   Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
