Detail guidelines for batch processing
NOTE: batch processing steps use the method of “piping” multiple commands directly in terminal screen. Alternative method is to use a shell script (*.sh). However, Mac Terminal allows copy/paste functionality. This makes things relatively easy to transfer multiple commands directly to the terminal window. Also shell scripts require special permissions.
