What is Batch: Definition and 37 Discussions

I am working on a project on vacuum drying vegetables using IR heaters. Before winter batch time was around 3 to 4 hours now it has increased to 6 hours. Any logic behind this as though the temperature drops and RH also drop so why has the time increased?

I don't know much about batch, but what I want is to execute a command such as ping google.com -n 200 and store all 200 ping latency results to a variable. The default results (avg max min %lost) isn't enough for me to tell if I can do what I need to do. I would like to calculate the average...
