Execute Process Task in Foreach Loop Container

How do I call cmd.exe in script task.

I am trying to change the file as read only. The file paths are derived from a table

1. Execute SQL Task - Returns the list of files that needs to be set read-only.

2. Foreach Loop Container-I am using Foreach ADO Enumerator in collections. I am using script task to make sure the file is available in that folder. If I use Execute Process Task, only the last record in the dataset is getting changed.
