Starting a Workflow using Powershell

Starting a workflow using PowerShell.

To start a workflow on a single list item , we can use the following PowerShell commands.

$web = Get-SPWeb -Identity https://mysite/workflow 

$manager = $web.Site.WorkFlowManager  

 $mylist = $web.Lists["Shared Documents"] 

 $association = $mylist .WorkflowAssociations.GetAssociationByName("On Item Created","en-US") 

 $data = $association .AssociationData

$items = $mylist .Items foreach($item in $items) 

 {  $wf = $manager.StartWorkFlow($item,$association ,$data,$true)

  }   

$manager.Dispose()

$web.Dispose()
