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
        The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
    .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 ExcludeDisabledJobs
        Switch will exclude disabled jobs from the output.
 
    .PARAMETER Database
        Return jobs with T-SQL job steps associated with specific databases
     
    .PARAMETER Category
        Return jobs associated with specific category
     
    .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.
