If you are referring to a batch or PowerShell script, this can be accomplished via ExecuteProcess [1] or ExecuteStreamCommand [2]. Both will allow you to execute processes on your host environment and collect its output to stdout from the execution in a resultant FlowFile for further processing. ExecuteStreamCommand additionally allows you to take an incoming FlowFile and pipe its content across stdin to the associated process.
