You can use this script to duplicate the SharePoint list with content or just list structure. You can set the $SaveData flag to $True to include the contents of the list.
This only works for lists with content that weighs less than 50 MB, please add a variant to actually copy all list items to the new list
That’s because of the default template size limit! You can increase it: Increase Maximum Size of Site Template, List Templates in SharePoint.
