An argument for _not_ splitting.
Huh? You can make md5sum handle each file in parallel and still present the output in the order given on the command line. To achieve this, each thread will process one file and submit the result to the main thread before exiting. The main thread will collect the results and output the result for argument k only after the results for 1...k-1 have been collected and output. Bruno
