You can use Windows PowerShell to add Text fields to a List in SharePoint 2010. Simply use the Add() method available on a fieldcollection. The example below demonstrates how to add a Text field to the Tasks list, set a Description and set the field as required. Note that the Add() method allows us to specify the Fields Name, the Type of Field and a Boolean value that determines if the field should be required.
